Geolocalised facility-level data from the European Pollutant Release and Transfer Register (E-PRTR) are used to calculate annual chemical-specific pollution, weighted by its toxicity. We combine the latter with regional data on employment, wages, and demographics sourced from Cambridge Econometrics, covering more than 1200 NUTS-3 regions in 15 countries, over the period 2007–2018. We employ quantile regressions to detect the heterogeneity across regions and understand the specificities of the 10th and 25th percentiles. Our first contribution consists in giving a novel and comprehensive account of the geography of toxic pollution in Europe, both at facility and regional level, disaggregated by sectors. Second, we regress toxic pollution (intensity effect) and pollutant concentration (composition effect) on labour market dimensions of left-behind places. Our results point to the existence of economic dependence on noxious industrialisation in left-behind places. In addition, whenever environmental efficiency-enhancing production technologies are adopted we observe associated labour-saving effects in industrial employment, but positive regional spillovers. Through the lens of economic geography, our results call for a new political economy of left-behind places within the realm of sustainable development.

They are tangible illustrations of geographies characterised by the coevolution of toxic industrial pollution and economic deprivation. Inspired by those examples, this paper intends to address the geography of leftbehind places from an environmental perspective. The existing literature has predominantly characterised left-behind places in terms of their economic and political dimension. We propose a new characterisation of left-behind places as territories in which socio-economic deprivation, measured as negative employment, wage, and demographic prospects, coexist with toxic pollution. To achieve this objective, we empirically examine the relationship between what we ex-ante identify as left-behind places – NUTS-3 geographical units located in the lower percentiles of labour markets, as measured by employment, wages, and demographic outflows – and toxic emissions. The theoretical rationale behind the link between toxic pollution and left-behind places is that the presence of a highly polluting facility in a given area might adversely affect regional economic development, both in terms of employment segregation in such facility and sector, inducing dependence on noxious industrialisation, but also in terms of the poor economic trajectory and bad specialisation. The latter highlights an economic development path unable to divert from a lock-in, potentially resulting in a decline in employment opportunities over time and a dampening effect on local labour markets (see relatedly Ash and Boyce 2018; Boschma et al. 2017). The presence of these facilities exerts a significant influence on a given territory, giving rise to both direct and indirect links with its economic development and labour markets. This can be attributed not only to the typically large size of the establishments but also, more fundamentally, to the materialist and historical roles these workplaces play in shaping the socio-economic dynamics of the involved regions. Geographic disparities co-evolve with path-dependent processes, the latter stratifying along different dimensions: advanced production and complex industrial diversification go hand in hand with high-innovative activities and good jobs (Rodrik and Stantcheva 2021), raising employment opportunities for the “winning” regions. On the other side, deindustrialisation, deterioration of productive capacity and locked-in productive activities with low complexity characterise left-behind places, with lowpaid jobs and reduced employment opportunities. So far, only a few case studies have been conducted in such places in order to highlight the role polluting activities play (Greco and Bagnardi 2018; Feltrin et al. 2021). In addition, the literature lacks both a quantitative way to identify such places and a comprehensive mapping of their actual status and evolution. Beyond the ecoK
Toxic pollution and labour markets: uncovering Europe’s left-behind places 339 nomic characterization of social inequality, what happens in terms of environmental inequality? Far from random order, the distribution of highly toxic industrial activity across regions tends to be concentrated as well, and it does so exactly in places experiencing socio-economic deprivation. In this respect, environmental and social inequality tend to stratify. More specifically, is toxic pollution linked to socioeconomic inequalities and industrial decay at the regional level? In order to address such question, we use geolocalised facility-level data from the European Pollutant Release and Transfer Register (E-PRTR) (European Commission 2006) to calculate annual chemical-specific pollution, weighted by CAS-number toxicity using the USEtox 2.12 model (Fantke et al. 2017). The E-PRTR contains environmental data from over 30,000 georeferenced industrial facilities in Europe, with information on quantities of 91 key pollutants released into air, water, and land. Our first contribution is therefore to produce a geography of toxic pollution. Accordingly, nowadays many left-behind places are still heavily dependent on fossil and other toxic industries, mainly producing metals, minerals, chemicals, and other raw materials. Given the geography of toxic pollution, our second contribution is to investigate the nexus between toxic pollution and the socio-economic spillovers on industrial labour markets. Therefore, our dependent variables are defined as left-behind places. Our explanatory variables are two indices of toxic emissions, one accounts for the sheer quantity of toxic emissions, the other accounts for quality improvements in the emissions’ mix. To create those indices, we aggregate facility-level pollution by sector at the regional level. Our analysis covers more than 1200 NUTS-3 regions for 15 European countries, over the period 2007–2018, and includes high-polluting traditional industries. Such empirical design allows us to detect potential lock-in dynamics in bad specialisation strategies. Therefore, our second contribution lies in identifying the particularities of left-behind places from a socio-environmental perspective. Third, after mapping toxic pollution to left-behind places, we study channels and sources of spillovers from industrial activities to the whole regional economy by moving from the geography of places to the geography of regions. We build two indices of pollution: a toxic pollution index, weighting the quantity of pollutants emitted by their toxicity (via CAS number), and a concentration index, capturing the pollutant portfolio at the facility level. The intensity of pollution, i.e., its overall toxicity, and the pollutant concentration are contrasted, by means of quantile regression, against the dynamics of left-behind places in terms of direct sectoral level links with industrial employment and wages, and indirect regional level links at the NUTS-3 level. By the latter, we study the potential spatial spillovers in the regions left behind, in terms of employment, wages, and demographic losses. We lay out two channels of toxic pollution propagation: a first-order channel according to which intensity of toxic pollution is positively associated with employment and wages at the industrial level. Not surprisingly, this result mainly holds for the lower quantiles of wages and employment distributions, therefore in favour of the noxious dependence that left-behind places have developed with industrial decay (Feltrin et al. 2021). A second-order channel according to which the reduction of the pollutant mix at the facility level, a proxy for technical change or inputs recombination in the context of environmental efficiency, is negatively associated K
340 C. Bez, M. E. Virgillito with industrial employment and wages, again with higher magnitudes for the lower quantiles of the distributions. In this respect, the abatement of toxic pollution via improved environmental efficiency processes might spur employment reallocation toward other, less noxious sectors of activity, rather than noxious industrialisation. We finally document the existence of spatial inequality feedback loops at the regional level, according to which toxic pollution is robustly negatively associated with net migration from left-behind places. Vice versa, the increasing concentration of the pollutant mix reduces the probability of relocation from a given place. The rest of the article is structured as follows. The following Sect. 2embeds the environmental dimension of left-behind places into an economic geography perspective. Sect. 3describes our data and methods, including how we construct our explanatory variables. The descriptive evidence in Sect. 4gives a nuanced account of the geography of toxic pollution in Europe, both at facility and regional level, and disaggregated by sector. Sect. 5explains our estimation strategy and shows the estimation results, for both the direct links focused on industry, as well as the indirect links with the regional economy as a whole. Sect. 6concludes and lays out several policy considerations. 2 The environmental dimension of left-behind places The economic geography literature has not yet devoted specific attention to the environmental dimension of left-behind places and neither to the geography of toxic pollution. Left-behind places are conceptually not so far from the South regions in uneven development theory (Prebisch 1950), which builds upon dependence, power structure, and persistent positional asymmetries (Pavlínek 2018; Leyshon 2021). However, uncovering left-behind places involves expanding the more traditional economic literature on North-South gaps and unequal development (Cimoli and Dosi 1995) with a territorial and geographical focus (Boschma et al. 2017). Such places have in common the experience of economic stagnation or even decline, depressed wages, demographic loss, and a general pattern of abandonment. This marginalisation was then compounded by the policy tendency to target urban agglomerations, “smart cities”, and innovative hub-clusters as main engine of economic growth (MacKinnon et al. 2022). Furthermore, the geography of discontent and left-behind places are closely related concepts. With the recent surge of populist and anti-system tendencies around Europe (Rodríguez-Pose 2018), for instance, the Brexit referendum (Goodwin and Heath 2016; Antonucci et al. 2017), left-behind places conceptually have received increasing attention. The ballot box backlash brought to the forefront socio-economic issues that have grown out of long-term tendencies, but have often been neglected by the economics literature. Hence, while deindustrialised, marginalised, and declining areas have moved out of policy focus, their urgent political relevance has sparked general renewed policy attention. The following subsections explain the intersection between a new conceptualization of left-behind places under the lens of economic geography. We mobilise two broad concepts, namely i) path dependence and regional lock-ins, and ii) the political economy of left-behind places. K
Toxic pollution and labour markets: uncovering Europe’s left-behind places 341 Path dependence and regional lock-ins constitute key mechanisms elucidating the materialist dimension of left-behind places. Lock-ins entail placeand historydependent paths occurring by means of the continuous reproduction of localised knowledge and socio-technological regimes. Specialisation, especially in the production of less dynamic and less complex products, pushes toward low growth trajectories and higher vulnerability to economic crises (Dosi et al. 2022). The properties of sectoral systems of innovations for economic development were recognised long ago (Malerba and Orsenigo 1996). Traditionally, heavy industries are expected to differ in their technological regimes of innovation and competition compared to others (Breschi and Malerba 1997). In fact, they are not susceptible to either high levels of innovation or intense competition (Tödtling and Trippl 2005). Therefore, ex-ante heterogeneity of between-sectoral pollution patterns is expected to be more relevant than within-sectoral ones. However, research on disproportionality (Freudenburg 2005; Collins et al. 2016) and co-pollutant elasticities (Dedoussi et al. 2019;Zwickletal.2021), looking at pollution at the facility-level, finds little evidence for “technological imperatives of a given sector” to pollute, also when controlling for size. In fact, in general, it seems that major polluters are often withinsector outliers characterised by a low rate of efficiency, indicating that environmental damage is often neither economically nor technologically required by the variety of production techniques available. In this respect, pollution, and particularly highscale toxic pollution, is a proxy for low-technological dynamism and absence of investment in efficient techniques of production, rather than a necessary externality of the sector. Consider, for instance, the well-known case of the ex ILVA steel plant in Taranto, Italy (Greco and Bagnardi 2018). The latter represents a clear combination of lack of technological upgrading, absence of investment in enhancing techniques of production, and purported employment-health trade-off, revealed by an ownership-managerial orientation historically resistant to promote technical progress in the plant. However, the mono-industrialisation pattern of the area has created a strong economic dependence in terms of job opportunities. Another example is the once-notorious Ruhr region in West Germany, especially the cities of Duisburg and Bochum (Fröhlich et al. 2022). Nowadays, this region is marked by a high incidence of toxic pollution and structural weakness, indicating the importance of equity considerations (Arora and Schroeder 2022). Grabher (1993) gives an in-depth explanation of the lock-in of regional development in the Ruhr area, once a complex industrial growth pole, deeply specialised in coal, iron, and steel. As we shall show, many industrial complexes, especially in the energy and steel industry, are still operating in this area, however, the social contract unraveled, and employment worsened or disappeared. As Grabher (1993) argues, the “weakness of strong ties” emerges as the main cause of such lock-in trajectories. Are left-behind places a necessary cost to pay for economic development? In the presence of toxic pollution, left-behind places can be considered industrial sacrifice zones (Lerner 2012). In such contexts, socio-economic erosion is a key agent necessary for the reproduction of spatialities of power marking the difference between cores and peripheries (Massey 2009). Exposure to toxic harm coupled with the slow decay of chemical change maintains and reinforces regional divergences. The conK
342 C. Bez, M. E. Virgillito cept of sacrifice allows to conceptualise toxic pollution as an intended imposition of power over a region and its inhabitants, creating an uneven toxic geography, and implies the “right to pollute” enabled by a naturalised economic power (Freudenburg 2005). Industries that are dirtier, more dangerous, and more threatening to human health present a special case for the spatiality of power, as conceptualised by Massey (2009). Around those industries, social and labour struggles are actually shaped by their objective relation with capital directed to polluting activities. Given that such places have materialist interests embedded into the production process, place and path dependency mutually reinforce each other, and lead to a lock-in of pollutiondependent growth. Indeed, the geography of toxic pollution might also help to understand the direction in which the political economy of left-behind places might manifest by means of the spatial reproduction of power. Certainly, toxic pollution is not the sole cause of economic decline. Indeed, there are plenty of places with high levels of exposure to toxicity which are not left behind from a socio-materialist perspective. In fact, in the following, we distinguish two different types of exposure to toxicity: an index of total weighted toxicity, which accounts for a size effect, and an index that measures any type of improvement in the composition of the portfolio of pollutants, in order to track upgrading trends in the pollution mix. Left-behind places are measured in terms of levels of the distribution of employment, wages, and migration flows. They are in the left part of the empirical distributions of these three labour market variables, depending on the quantile regression that will be estimated. We expect, following the lockin hypothesis, that those areas will be more dependent on toxicity, as a first-order channel. At the same time, we expect that any path of industrial upgrading will incorporate less polluting but also more efficient techniques, or input combinations, and in that require less employment. 3 Data and Methods Our aim is to give an account of the geography of toxic pollution in Europe, to then study the co-evolution of toxic pollution on economic deprivation, in particular with respect to employment, wages, and net migration flows. This allows us to investigate the environmental dimension of left-behind regions. We combine two datasets in a novel way: facility-pollution data and regional economic data at sectoral level, covering more than 1200 regions in Europe, over the period 2007–2018. Sect. 3.1 describes the dataset of facility-specific industrial pollution sourced from the E-PRTR, from which we calculate two measures at the sector-region-year level. The first index is the facility-level pollution augmented by its toxicity which informs about an intensity effect (Sect. 3.2), while the second is a pollutant concentration index which informs about the mix of the facility pollutant portfolio (Sect. 3.3). Sect. 3.4 presents the industry-level distribution of the constructed indices. Sect. 3.5 describes the set of outcome variables sourced from Cambridge Econometrics (employment and wages) and Eurostat (migration), which illustrate the different dimensions of left-behind places. K
Toxic pollution and labour markets: uncovering Europe’s left-behind places 343 3.1 Industrial facilities, sourced from E-PRTR We get facility-level pollution data from the European Pollutant Release and Transfer Register (E-PRTR) which provides environmental data from industrial facilities in European Union Member States, Iceland, Liechtenstein, Norway, Switzerland, Serbia, and the UK (European Commission 2006). Starting from 2007, the register has been updated every year with annual data reported by some 30,000 industrial facilities covering 65 economic activities. Each active industrial facility is required to provide annual information on the deliberate and accidental quantities of pollutants released to air, water and land. This data covers 91 key pollutants including heavy metals, pesticides, greenhouse gases and dioxins. The E-PRTR defines a pollutant as “a substance or a group of substances that may be harmful to the environment or to human health on account of its properties and of its introduction into the environment” (European Commission 2006, Annex I, Article 2, p.74). Hence, the E-PRTR gives insights into the releases and transfers of regulated substances of the largest industrial complexes in Europe. Annex I of the E-PRTR Regulation lists 65 activities, grouped into 7 activity sectors.1The information to which sector a facility belongs allows for an industry-specific analysis.2 To build our original data set, we select emissions released by air, taking into consideration both deliberate and accidental emissions, and drop facilities with data entries for five or fewer consecutive years, as we want to focus on polluters that have shown some degree of continuity with regard to their presence in and hence possible impact on the territory.3Facilities that did not exceed a threshold of emissions as established by the Commission (2006, pp. 83–86) do not have to report in the E-PRTR in that specific year (even though these facilities were still operating), which leads to missing data within the facility-specific time series. If pollution records are missing in one or more years, but are present before and after, we perform a linear interpolation in order to control for those missing values.4 We are focusing on the countries where most facilities are located, i.e., countries with a considerable level of industrial activity. By definition, the nexus industrial pollution-employment dynamics is less interesting in regions with little to no industrial pollution, as suggested by the E-PRTR data. Hence, to sharpen our analysis, we drop the countries that belong to the lowest five percent in terms of the number of 1These sector are: agriculture and leather industry, chemical industry, energy, production and processing of metals, mineral industry, paper and wood production and processing, waste and waste water management. 2An extensive overview of the E-PRTR classification including a detailed description of all activities covered by our data can be found in the Appendix, Table 8. 3The minimum presence in the data set is one year, the maximum 13. On average, a facility has pollution entries for ten years. Eleven percent of facilities are present in the data base for five years or less. Those are the facilities that we exclude from the analysis. 4This is motivated by the assumption that missing values, i.e., gaps, arise from the threshold issue. Missing years at the beginning or the end of the time period instead indicate the ceased activity of a facility and therefore are not interpolated. This is analog to the procedure proposed by Rüttenauer and Best (2021b), being confronted with the same E-PRTR data issue. Linear interpolation however only affects a small portion of the entire emission data set (1.78 percent), ruling out the threat of a systematic bias. K
344 C. Bez, M. E. Virgillito polluting facilities. This leaves us with the following 15 countries: Austria, Belgium, Czech Republic, Germany, Spain, Finland, France, UK, Greece, Italy, Netherlands, Poland, Portugal, Romania, and Sweden. The top ten polluting facilities of the four most toxic sectors (energy, metals, minerals, chemicals), ranked by the sum of emitted pollutants over all years, are presented in Table 1. It lists the names of the facilities as well as the countries and cities that host such facilities, which provides a first glimpse of the detailed information provided by the E-PRTR dataset. 3.2 Measuring toxic pollution The E-PRTR allows to disentangle pollutants and their underlying toxicity. Indeed, it is well known that pollutants from industrial facilities are dangerous to human health and the environment. The amount of pollution and its pollutant mix is a result of the existing technologies and production processes of the industrial system. Although progress has been made in terms of reduction of the environmental impacts of toxic pollution from industry through regulations and bans, the evidence tells us that there are still innovative search efforts around toxic chemical components (Biggi et al. 2022). Moreover, as we shall see, even banned compounds are still present in the E-PRTR, for example hexachlorobenzene and polychlorinated biphenyls, which are banned globally and universally. They belong to the ten most toxic pollutants present in the data. In terms of toxicity, the chemical with the highest toxicity in absolute is mercury and its compounds (HG), which clearly emerges as an outlier being twelve times more toxic than the average compound in the data set, and is a highly potent neurotoxin that is closely linked to energy production. For instance, in 2020, the EPA proposed to roll back its Mercury and Air Toxics Standards (MATS) as regulatory limits on hazardous air pollution from coal-burning power plants (EPA 2019).5It is hence crucial to account for pollutant’s toxicity which differs widely across pollutant groups and single compounds. Given the heterogeneous toxicity of the different pollutants, we weigh pollutants by their toxicity. We focus on long-term exposure to all pollutants that are known to be dangerous to human health. Out of the original 91 key pollutants we retain 41 distinct pollutants, whose toxicity varies by several magnitudes.6The chemical group of heavy metals is the most toxic; at the same time, they are frequent due to wide industrial applications. As said, the data set also shows the presence of several pollutants that have been banned worldwide since the Stockholm convention from 2001. We account for the variation of toxicity by weighting the quantity (mass in kilogram) of each pollutant by a toxicity weight that we source from the USEtox 2.12 data base (Fantke et al. 2017), as shown in Eq. 1. We match pollutants with their respective toxicity via information on Chemical Abstracts Service numbers (short 5This decision is based on cost-benefit analyses, trying to economically justify industrial contamination and disregarding the significant health and environmental benefits by reducing a broad range of hazardous air pollutants, especially mercury, as argued by Aldy et al. (2020), see also Ofrias (2017). 6The full list of toxic pollutants retained for this analysis can be found in the Appendix, Table 7. K
Toxic pollution and labour markets: uncovering Europe’s left-behind places 351 Fig. 3 Total toxic pollution by industry, disaggregated by pollutant groups, and ranked from industry from highest toxic pollution to lowest, over 2007–2018. Source: Own calculation based on E-PRTR shows the disaggregation of such pollutant groups by industry. The pollutant group of heavy metals account for the largest share of toxic pollution across all industries, except for the chemical, agriculture, and leather industries, whose pollutant portfolios vary significantly. The energy and metal industries are the heaviest polluters, and their sectoral characteristics show high percentages of heavy metals compared to other pollutant groups: approximately 50 percent of toxic pollution coming from energy is associated with the release of heavy metals, while this share increases to approximately 70 percent for the metal industry (see blue segment of bars). Within the energy sector, the release of mercury and other highly noxious heavy metals is mostly associated with coal combustion but also oil-fired power plants (EPA 2019). This makes the alarming case for the biggest industrial emitters of globallyharming CO2, often situated in proximity to urban zones, being also a highly dangerous local polluter. Next, we explore the inter-industry variability of our measures of toxic pollution and how they evolve over time. For doing so, we depict mean toxic pollution, in logs, and mean pollutant concentration, as by the index HHI, by industry over time (see Fig. 4). The overall time trend of toxic pollution is slightly decreasing, meaning that most industries were able to moderately curb their toxic emissions down. The metal, waste and wastewater, and paper and wood production industries, however, show a stagnating trend over the period 2007–2018. The pollutant concentration index is a proxy for technological efficiency at the sectoral level, e.g., the end effect of the adoption of pollution-abatement technologies, potentially induced by environmental regulations, that reduce the number of co-pollutants emitted. As shown below, the index increases over time, i.e., the average number of pollutants by region and sector decreases as facilities on average reduce their number of pollutants by approximately 20%: from 0.41 in 2007 to 0.49 in 2018. The HHI measures the production of co-pollutants especially in the energy sector, where CO2is the main pollutant. However, for the remaining industries, it is mainly a proxy for environmental and technological efficiency. K
352 C. Bez, M. E. Virgillito Fig. 4 Mean toxic pollution by industry from 2007 to 2018 (upper panel) and mean concentration index of pollutants by industry from 2007 to 2018 (bottom panel). Source: Own calculation based on E-PRTR Across-industry variability of both measures is very high. The energy and the metal industries clearly emerge as the two most pollution-intense and toxic industries (see blue and dark red line in upper panel), while other sectors contribute very little to overall levels of toxic pollution, for instance, waste and wastewater (orange line), and agriculture and leather industry (green line). Average pollution concentration is more clustered than toxic pollution. With regard to the former, the agriculture and leather industry emerges as an outlier, with an index close to one, indicating mono pollution. The energy industry has the lowest pollutant concentration index, i.e., on average is the industry that emits the highest number of different toxic pollutants (blue line in bottom panel), followed by the metal industry (red line in bottom panel). Higher levels of toxic pollution are on average associated with lower levels of pollutant concentration, i.e., tend to have multi-pollutant portfolios as they emit a great variety of different chemicals. A scatterplot confirms such an inverse relationship. Fig. 5plots unweighted pollutant concentration against toxic pollution. Every dot of the same color represents one country in our sample. The clear negative relationship indicates that on average facilities with a multi-pollutant portfolio also are bigger emitters. The within-industry clustering, especially evident for industries such as minerals (see grey cross symbols) or metals (see blue cross symbols), reflects industry-speK

For instance, there are countries in the chemical industry that have comparable levels of toxic pollution but different types of pollutant mix, i.e., pollutant concentration indices (see, for instance, the vertical variations of the black triangle symbols). 3.5 Regional Economic Variables: Cambridge Econometrics Next, we turn to the regional economic variables. With these variables, we aim to depict the local labour market in left-behind regions, often characterised by precarious employment, underemployment, and demographic changes. The labour market data come from Cambridge Econometrics, which combines regional and sectoral data from both Eurostat’s REGIO database and AMECO, which is provided by the European Commission’s Directorate General Economic and Financial Affairs. The disaggregated data is available for 27 EU countries (all EU member states except Malta) at NUTS-3 level and six sectors from 1990 to 2018.13 From this data base, we use employment (both industry and total) which “covers all persons engaged in some productive activity” and wages (both industry and total) for the countries 13 These are: A (agriculture, forestry and fishing), B-E (industry), F (construction), G-J (wholesale, retail, transport, accommodation and food services, information and communication), K-N (financial and business services), and O-U (non-market services).

In addition, we source population changes from Eurostat’s “demographic balance and crude rates at regional level”. In specific, we look at crude rate of net migration, which represents total population changes cleaned for natural changes (births and deaths). It is expressed as the change of the population in region rover the past four years.14 4 Geography of Toxic Pollution Our first contribution consists in giving a novel account of the geography of toxic pollution in Europe. Below is shown the spatial distribution of the industrial facilities in our data set. Emission quantity is expressed in kilograms, weighted by human toxicity of each pollutant, and summed by facility and across all years in the sample, 2007–2018. The size of the dots is proportional to the amount of toxic pollution released per facility, aggregated into four clusters. The color indicates to which broad activity the facility is associated, as described in the legend of Fig. 6. Most industrial facilities are located in France, Spain, Germany, and the UK. Furthermore, industries are clustered within countries and regions. We thus carry out our analysis at the sectoral level, not least because sectors are very heterogeneous with respect to toxicity levels and emission quantities. Zooming in, the example of Germany (Fig. 6.b) shows that the facilities that emit the largest amount of toxic pollution are from the energy sector (green large dots). They mostly belong to coal-fired power stations, located in the Rhine area (state of North Rhine-Westphalia, Western Germany) and in Lusatia (state of Saxony, Eastern Germany). However, also other industries are home to major polluting facilities, for example “Werk Schwelgern”, one of Europe’s biggest steelworks, also located in the Rhine area (city of Duisburg). Indeed, a recent study on structurally weak regions in Germany points to the cities of Duisburg and Dortmund – both in the Rhine area heavily impacted by deindustrialisation –, as well as several areas in Eastern Germany (Bitterfeld-Wolfen and Vorpommern-Greifswald) (Das Progressive Zentrum 2022). This anecdotal evidence points to a potential link between the presence of highly toxic industrial complexes and regional economic deprivation. The E-PRTR provides geospatial information, i.e., longitude and latitude, for every facility. We use the latest Administrative Level data from Eurostat (2021) and use the same NUTS-3 borders for all years. We attribute a NUTS-3 level code to every point, i.e., a facility’s geolocation, that falls within a polygon from the shapefile.15 This matching strategy results in a data set of approximately 69.000 industry-regionyear pairs nested within 1.215 NUTS-3 regions (this methodology is explained, for 14 Sect. 2 of the Appendix shows a map of employment at NUTS-3 level in Europe and the descriptive statistics of the regional economic variables using violin plots, see Figs. 8and 10, respectively. 15 In this way, offshore facilities get dropped from the data set, for instance oil and gas platforms.

Source: Own calculation based on E-PRTR Fig. 7displays the distribution of toxic pollution in logs and averaged over the years 2007–2018 across European NUTS-3 regions in the data set. This map shows patterns of clustering of toxic pollution: a highly polluted region is likely to be in geographical proximity to another polluted region. Such clusters are visible in particular in Spain, the UK, Germany, Poland, the Czech Republic, and Romania. Moreover, we notice that the polluted regions encompass both urban-deindustrialised (i.e., Ruhr Valley) as well as rural types of territories (i.e., North Finland). We proceed in a similar way to regionally aggregate the concentration index of pollutants (HHI). We aggregate the HHI at sector-region-year level, and weight it by the contribution of each sector to the overall regional toxic pollution, expressed as a percentage (see right part of the equation). The weighted sectoral HHI is then written as: HHIsrt DPN iD1HHIit Nsrt Tox Pollsrt Tox Pollrt :(4) This regional concentration index has a mean of 0.22 and a standard deviation of 0.25. Once aggregated, the heterogeneity of the HHI becomes especially visible across industries, with facilities belonging to the energy, metals, and paper industries having the highest number of distinct pollutants (so-called multi-polluters), and therefore lower values of the concentration index.

Toxic pollution and labour markets: uncovering Europe’s left-behind places 357 5 Toxic pollution and labour markets in left-behind places In the following, we present our econometric specification, divided into direct links, estimated for the industrial labour market, and indirect links, estimated at the regional level, including therefore also non-industrial labour markets. In both cases, we are interested in detecting the links between toxic pollution and employment, wages, and migration (in the regional estimation), in order to characterise the labour market associations in left-behind places. 5.1 Econometric Specification We use quantile regressions as in Koenker and Hallock (2001) to estimate our dependent variables. Quantile regressions are advantageous because they allow us to analyse the different roles of toxic pollution for left-behind places, located in the left tail of the distributions, vis-à-vis the rest. In this way, we take into account the heterogeneity across regions regarding employment and wage levels, as well as demographic changes. Furthermore, this estimation method is more robust to outliers than OLS models and does not require assumptions about the parametric distribution of the error term (see Koenker and Hallock 2001). We estimate percentile equations for the 10th, 25th, 50th, 75th, and 90th percentiles. Quantile Regression methods allow flexibility in the estimation of the coefficients, enabling us to obtain a range of conditional quantile functions (CQF), which in our case will be given by the employment, wages, and migration CQF. Furthermore, we take into account that there are regions in the dataset for which toxic pollution is zero due to the absence of a large industrial facility in that area. This implies recoding region-year pairs for which we do not have data on toxic pollution as zero.16 Hence, our predictor is left-censored, meaning that we can observe toxic pollution only above a certain threshold, as established by the E-PRTR regulation (European Commission 2006) and our own methodology that drops noncontinuous polluters. We also find that the average employment and wage difference between polluted and censored regions is positive. To correct for the censoring, we introduce a binary indicator variable at region-year level, Indicatorrt, as specified in Eq. 5.17 Following this approach, we estimate baseline specifications of the following general form: LBrt D˛sC˛cC˛tCˇ1log.Tox Poll/srt CIndicatorrt CXrt C"rt;(5) where the dependent variable LB, “Left-Behind”, is a vector that takes into consideration three different dimensions of being left behind of a given NUTS-3 region r in year t: log of employment, log of wages, and net migration. This is regressed on sectoral toxic pollution, in logs, computed at the regional level. The nested nature 16 For 23.7 percent of the data set, we observe the economic variables, but do not observe the level of toxic pollution. 17 Note that the indicator takes the value 1 for a censored region, i.e., when there is no observed pollution, and 0 otherwise. K

Virgillito of the empirical specification allows for taking into account sectoral heterogeneity, which emerges as a key facet of the emission data.18 Sectoral toxic pollution is the amount of pollution weighted by toxicity and emitted at the regional level in sector sat time t.Indicatorrt is the dummy for the censored regions, for which we do not observe any toxic pollution. ˛s,˛c,and˛tare sector, country and year fixed effects, respectively. Xrt represents the set of control variables, which are (four-years) lagged gross value added (gva) per capita and lagged employment.19 Both variables control for regional economic activity. Gva is a proxy of the sectoral production/demand, while lagged employment accounts for feedback effects from past levels of employment.20 Moreover, by including gva, we account for the potential contracting force that the financial crisis has had, e.g., depressing industrial production, being asymmetrical across European countries and regions, as laid out in Dijkstra et al. (2015); Davies (2011); Groot et al. (2011), all pointing to spatial heterogeneity regarding crisis sensitivity. Finally, standard errors are bootstrapped. While toxic pollution is a measure of intensity and dangerousness, the concentration index adds the notion of pollutant mix, or negative quality, to the analysis. On average, sectors with multi-pollutant profiles also have higher levels of toxic pollution as shown in Figs. 4and 5. We hence augment the baseline specification by introducing the pollutant concentration index HHIsrt at sector-region-year level:21 LBrt D˛sC˛cC˛tCˇ1log.Tox Poll/srt Cˇ2HHIsrt CIndicatorrt CXrt C"rt:(6) 5.2 Direct links: Industrial labour market We consider as direct the first-order associations at the industry level. We look at the links between toxic pollution and pollutant concentration, and industrial labour markets in terms of employment and wages. Table 3departs from the baseline specification as written in Eq. 5. The estimation of different percentiles provides a nuanced picture of left-behind places (defined as the 10th and 25th percentiles) vis-à-vis the rest. For employment in industry,22 which we refer to as industry employment, we find a positive and significant relationship, particularly for the lower 18 We perform a robustness check where we aggregate sectoral toxic pollution by region on the right-hand side of the equation, hence abstracting from the industrial dimension and focusing solely on the regional level. This leads to a regional-level empirical specification where the level of analysis is identical on both sides of the equation. This reduces the sample size approximately by half. The qualitative results with this alternative setup remain the same compared to the baseline specification, stressing the robustness of our findings. 19 We carry out a robustness check on the control variables by using different lags, from two to five years. However, this does not change the qualitative results of the analysis. 20 The inclusion of the lagged employment variable is standard in the estimation of labour demand equations. 21 A Wald test between the baseline and the augmented specification confirms the statistical significance between those models. 22 “Industry” refers to industry as a whole and is consistent with the NACE Rev. 2 sectoral definition. It is the lowest level of aggregation for which NUTS-3 level data is available. K

360 C. Bez, M. E. Virgillito end of the distribution, i.e., the 10th and 25th percentiles (columns 1 and 2). The link decreases along the quantiles, becoming even negative in the 90th percentile, even though not significant. Hence, we find the association to be mostly limited to what we identify as left-behind places, which are characterised by weak labour markets. For instance, for the 10th percentile, a 1 percent increase in toxic pollution is associated with a 0.014 percent increase in industry employment. The result highlights the economic dependence, above outlined, that left-behind places manifest with noxious industrialisation. In addition, it points to poor economic trajectories and bad specialisation in those places whereby industry employment, even though potentially of poor quality, is directly linked to the presence of noxious facilities. For the regions characterised instead by higher levels of employment, the lack of significance points to a decoupling between industry employment and toxic pollution. Indeed, the higher the employment level of a given region, the higher the economic performance therein, and the lower will be the burden exerted by bad specialisation, here proxied by pollution at the sectoral level. Therefore, employment dependence on toxic pollution overall decreases along the conditional distribution of employment. For industry wages, a comparable picture emerges. While the coefficient of industry wages is positive for left-behind places (columns 6 and 7), the association becomes negative for the higher quantiles. Hence, within regions with low industry wages, toxic pollution is positively associated with wages, again signaling dependence on the sector, while in regions with already high industry wages, the association gets negative. The association for the 10th percentile is comparable in magnitude with the median, however of opposite sign. The opposing association for left-behind places vis-à-vis the rest is in line with the notion of spatial inequality feedback loops as pointed out by Pinheiro et al. (2022). The declining co-evolution of toxic pollution along the wage distribution, similar to the employment dynamics, suggests that in high-wage regions, take the example of Bavaria, highly toxic facilities have a penalizing effect on wages. These results therefore highlight the relationship being heterogeneous along the conditional distribution of both industry employment and wages. At the same time, they suggest that OLS estimation clouds such heterogeneity, undermining the specialty of left-behind places. Such heterogeneity therefore strengthens the case for our choice of applying quantile regression to the data. Furthermore, the indicator for the censored regions is always negative and significant and increases monotonically along the employment and wage quantiles. Hence, in left-behind regions (first two quantiles), the difference in labour market variables between polluted and non-polluted areas is greater. The negative relationship is mainly due to the degree of industrialisation and industrial activity, which has a direct effect in terms of both economic development of the area and higher pollution levels, when compared with e.g., rural areas where industrial activities are not present. Overall, we document that toxic pollution impacts especially the leftbehind places. Lagged gva per capita is negative in the lower quantiles, indicating a regional employment change towards sectors other than industry, possibly activated by noxious deindustrialisation. Lagged employment is always positive, with high persistent magnitudes which decrease along the distribution. Generally, left-behind places are considered to be both low-industry employment and low-industry wages areas (as per our definition, see above), in line with the fact K
Toxic pollution and labour markets: uncovering Europe’s left-behind places 367 Related to the question of why or how toxic pollution aligns with economic deprivation, the first index holds significance. It relies on the weighted amount of toxic emission by region, functioning as an indicator of regional-level specialisation. This concentration manifests in specific industrial sectors, captured by their level of toxicity. Indeed, pollutants are highly sector-specific, as Fig. 1highlights (also see various reports by the International Energy Agency, e.g., OECD et al. 2016). In that way, the first index allows studying the extent to which toxic pollution – emerging from sectoral specialisation of a given territory – affects the local labour market. In this context, the theory of territorial lock-in and path dependency upon high-toxic industrial sectors becomes pertinent: left-behind regions exhibit a stable and positive relationship with toxicity in terms of employment and wages (compare Sect. 2). This phenomenon is attributed to the pronounced economic dependence of the territory on highly-toxic industrial sectors. Apart from industrial lock-in, it is essential to consider potential paths for upgrading or downgrading in terms of toxic emissions to comprehend the trajectory of the territory. In this respect, the second index we propose captures the extent to which the composition of the pollutant portfolio has changed over time: less toxic portfolios are a proxy of an upgrading path, vice-versa, more toxic portfolios are a proxy of a downgrading path. Therefore, the HHI index captures the channels not of pollution as such, but rather as a proxy of the evolution of the lock-in trajectory. Indeed, the index presents a stable and negative relationship with employment and wages at the industry levels only in left-behind places, while it is not significant in non-left-behind places. The rationale behind this is that it represents a proxy for technological upgrading of the region, incorporating less emitting but also less labour-intensive technologies. 6 Conclusions and policy implications Arguably, the contemporary crises overlapping across social, economic, and ecological spheres are creating systemic inequalities across space. We conceptualise left-behind regions through economic deprivation and explore their environmental dimension. We explore the co-evolution of toxic industrial pollution and socio-economic deprivation through channels of path dependence, regional lock-ins, and the labour-saving effects of technology, therefore adopting the lens of economic geography and its scope of interpretation as a useful toolbox to address environmental inequality. Using data for 15 European countries at NUTS-3 level, after providing one of the first comprehensive attempts to map toxic pollution in Europe, we employ quantile regression to study how toxic pollution and pollutant concentration impact disproportionally the left-behind regions. All in all, our findings trace histories of industrial decay, providing evidence that persistent exposure to pollution works as a compounding factor aggravating already existing socio-economic deprivation. This has compelling implications for sustainable development. We find opposing results for left-behind places vis-à-vis the rest, pointing to spatial inequality feedback loops. Due to path dependence in industry, such left-behind places, often materially dependent on toxic industries and K
368 C. Bez, M. E. Virgillito with a heavily impaired environment, find themselves locked in their poor economic trajectories, and bad specialisation path they have evolved into. Therefore, for such left-behind places, the trade-off between health and employment kept being perpetuated. In fact, Lerner (2012) uses the term “sacrifice zones” which jointly conceive environmental toxicity and economic disinvestment. This concept has recently been developed further by Feltrin et al. (2021) to coin the term “noxious deindustrialisation” as left-behind places where ongoing pollution and underemployment coexist. Hence, while the sustained release of industrial toxic pollutants disrupts human, environmental, and economic health, it maintains the status quo of reproductive and social disparities. The political economy of left-behind places would suggest that a transition of technological systems towards a zero-toxic world requires the co-evolution not only of productive forces and technological domains but also of political structures currently too much favouring inertia. Taken at large, the relationship between labour, capital, and the environment laid bare in the analysis raises questions about the environmental and societal sustainability of capitalism (Faber 2008). The empirical analysis strongly supports the need for a place-sensitive regional policy, with an urgent focus on left-behind places, which can guide the new Just Transition Fund (2021–2027) and EU cohesion policy. In order for environmental and climate policies to even out territorial inequalities, policy-makers have to take into account local contexts in terms of industrial specialisation, technological lockins, employment segregation as well as the materialist and economic dependence on highly toxic industries. Moreover, the results of our place-based analysis help to partially overcome the productivist opposition between labour and environment, as we show that whenever processes of environmental-technological upgrading are undertaken, they tend to crowd out workers from the industrial labour market but are associated with positive regional spillovers, improving labour market variables overall. Thus, regions where fewer toxic pollutants are emitted are regions with inmigration flows, while the opposite is true for regions characterised by a highly diversified, highly polluting mix of pollutants. Furthermore, it is crucial to understand the policy implications of a labour-saving effect of environmental technology in polluting industries. A very recent publication by the International Monetary Fund (IMF) lays out the high geographical concentration of high-polluting jobs (Bluedorn et al. 2022). However, the report stresses the issue of labour reallocation, given that individual workers are less likely to successfully reallocate to greener jobs, hence compounding the disadvantages of already left-behind people and places. Behind the impediment of a labour transition away from toxic and fossil-dependent occupations towards greener ones is the lack of an industrial policy able to create coordinated policy actions to govern the twin (technological and ecological) transition (Bianchini et al. 2023). Although growing, “green jobs” do not represent a sector per se but are rather occupations related to the production of potentially “greener goods”. However, they hardly might represent the solution for entire sectors and related supply chains under deep organizational and productive restructuring, such as automotive. In this respect, place-based policy initiatives must coexist with coordinated European industrial policies (Cimoli et al. 2009) aiming to build productive but sustainable capacity in the near future.

Toxic pollution and labour markets: uncovering Europe’s left-behind places 369 behind, peripheral regions ought to be the starting point for this type of policy action, with guided reconversion and socio-economic upgrading. Finally, our paper also connects to the broader concept of the geography of discontent. If toxic pollution contributes to a place being left behind, then the environmental dimension might matter for politics, i.e., populist stances, which however are mostly anti-environmentalist. Instead, left-behind places would have reason to become subjects in environmental struggles in general and the Green New Deal in particular, due to their materialist dependencies on toxic economic growth. In this regard, economists are advised to apply environmental justice approaches to contemporary environmental challenges. This points to the general need to bring deindustrialised and marginalised places back into policy focus, apart from their political relevance. Future lines of research include, firstly, the use of spatial econometric techniques to detect spatial correlation processes across left-behind places. Second, a study of growth patterns at the facility level could be useful to distinguish between “growth by pollution” and “growth by decontamination” strategies. Thirdly, research could delve into the materialist histories of left-behind places by looking at micro-level data on workers, examining labour market outcomes, and intersecting class and gender dimensions of environmental justice (Faber et al. 2021). 7 Appendix 7.1 Details on E-PRTR data sample: pollutants and sectors Table 7 Summary table of 41 distinct toxic pollutants and CAS numbers as in our E-PRTR sample, listed by pollutant groups and ranked according to their USEtox 2.12 toxicity score Pollutant name Pollutant CAS Pollutant group name Toxicity score (USEtox 2.12) Tetrachloromethane 56-23-5 Greenhouse gases 0.0000974 Hydrochlorofluorocarbons 593-70-4 Greenhouse gases 0.0000301 Halons 1897-45-6 Greenhouse gases 4.71E-03 Chlorofluorocarbons 75-69-4 Greenhouse gases 1.75E-04 Hydro-fluorocarbons 811-97-2 Greenhouse gases 1.52E-04 Fluorine and inorganic compounds (as HF) 75-02-5 Halogens 0.0000756 Chlorine and inorganic compounds (as HCl) 136-40-3 Halogens 0.0000281 1,1,2,2-tetrachloroethane 79-34-5 Halogens 0.0000205 Mercury and compounds (as Hg) 14302-87-5 Heavy metals 3.49 Cadmium and compounds (as Cd) 22537-48-0 Heavy metals 0.195 Arsenic and compounds (as As) 17428-41-0 Heavy metals 0.0538 Chromium and compounds (as Cr) 18540-29-9 Heavy metals 0.0465 Lead and compounds (as Pb) 14280-50-3 Heavy metals 0.0428 Zinc and compounds (as Zn) 23713-49-7 Heavy metals 0.0155 K
