Energy and climate goals may require a speedy phase-out of old appliances, whereas material resource and social concerns may call for repairing and reusing air conditioners as long as possible. Demand for space cooling is soaring globally, increasing regulatory pressure. In middle income countries such as the Philippines, the market for second hand room air conditioners is sizeable. This study targets the question when and how to regulate the market for used air conditioners to balance green and social goals. It analyses the second hand market for air conditioners in Metro Manila, uncovering the general supply chain, business models and customers as well as energy efficiency, refrigerant and repair practices. The study draws on qualitative interviews with 10 experts and 29 retailers and technicians active in the semi-formal second hand market for air conditioners. Available information of lifecycle analyses is taken into account, but the focus of this contribution lies on social impacts of potential regulation. Overall, short-to-medium interventions in the second hand market are required to balance environmental and social goals that target the different players in the market: construction industry, brokers, retailers and technicians, customers and scrap dealers. Neither a complete ban nor delaying or foregoing regulation is advisable. Specific policy recommendations are derived. Keywords Air conditioners· Philippines· Energy efficiency· Climate change· Reuse· Repair Introduction Policymakers and technical cooperation agencies around the world tend to focus either on the active phase-in of new green technologies or on the end-of-life (e-waste) stage, neglecting the stage in between. The decisions if, when and how to speed up the phase-out of old appliances deserves more attention. In many low- and middle-income countries, large second hand markets for used appliances such as air conditioners (AC) exist. Apart from * Babette Never [email protected] 1 IDOS German Institute ofDevelopment andSustainability, Tulpenfeld 6, 53113Bonn, Germany 792 Circular Economy and Sustainability (2023) 3:791–810 1 3 health and safety requirements and guidelines on e-waste that generally encourage reuse of technologies, more concrete regulations on used appliances such as ACs are missing in many low- and middle-income countries this far. From an energy and climate perspective, taking old ACs off the market as quickly as possible seems desirable [7]. However, a material resource and lifecycle lens may change the picture. Furthermore, social questions of affordability in low- and middle-income countries rather call for prolonged use of cheaper, repaired ACs. Managing this complexity requires political attention to growing second hand markets. The demand for global space cooling and, correspondingly, the sales numbers of room ACs are soaring, especially in tropical middle-income countries such as the Philippines. Energy demand for space cooling is expected to triple globally till 2050 [18]. The room AC market in the Philippines was already sizeable with approx. 700,000 new units sold annually in 2016; it increased to approx. 900,000 units in 2018 [12, 31]. Growth trends in the room AC market are expected to continue strongly on the back of more home staying activities and a very limited online market, in spite of overall economic impacts of the COVID-19 pandemic. These market dynamics present a challenge from an energy security perspective, but also from a climate change perspective. Global warming effects deriving from both electricity use of ACs (if non-renewable electricity source) and climate-harmful refrigerants in the AC are tremendous. Globally, energy efficient, climate-friendly cooling could save up to 8years of global emissions at 2018 levels (IEA 2020). For the Philippines, cooling sector emissions are expected to rise from 24.7 MtCO2eq in 2017 to 44.6MtCO2eq in 2050 in a business as usual scenario [12]. In parallel, positive impacts of AC ownership and use on human development are fairly clear. Studies have found better health (sleep, disease control) and higher productivity in cooled environments [4, 20, 21]. A growing AC market is likely to have positive employment effects on local technician and service enterprises. Moreover, many livelihoods depend on formal and informal scrap dealing and recycling of e-waste, including ACs [1]. Therefore, an emphasis to forego the purchase of ACs should not be the primary political strategy in tropical middle-income countries, but rather a market transition to green ACs. Green ACs can be energy efficient and contain climate-friendly refrigerants such as R290. In contrast, repairing, reusing and recycling appliances such as ACs can make sense from a lifecycle perspective and to support the move towards a circular economy [5, 17]. Additionally, socioeconomic benefits of repair services and trade of used goods in terms of employment and income need to be taken into account. Thus, the existence of a second hand market for ACs in low- and middle-income countries is not necessarily bad. The key question then becomes: Under which conditions and how to regulate the second hand AC market to balance energy, climate, resource and social impacts? This contribution aims to help answering this question with a social science analysis of the current second hand AC market in the national capital region of the Philippines, known as Metro Manila. It analyses prevalent business models, sales, prices and customers as well as energy efficiency practices and resource use in the market. Policy options for balancing environmental and social goals will be derived with an empirical focus on social goals and impacts of potential regulation on various stakeholders in the market. While it is hardly possible to reliably quantify the size of the market for used or “second hand” room ACs in the Philippines, it is safe to assume a substantial market size that requires political attention. According to the Refrigeration and Air Conditioning Technician Association of the Philippines (RACTAP), there are approximately 5,000 AC technicians in Metro Manila alone, possibly more, as not all are registered with RACTAP. 793 Circular Economy and Sustainability (2023) 3:791–810 1 3 Many technicians are also retailers of ACs. A conservative estimate: if only half of these 5,000 retailer-technicians sold 20–30 used AC units per year, this would already amount to 50,000–75, 000second hand ACs sold in Metro Manila alone. Extrapolated to all of the Philippines, the numbers of used ACs sold annually could likely reach 200, 000–300, 000, roughly a third of the market for new units. At the time of writing, the second hand AC market was unregulated apart from a general hazardous waste disposal requirement, health and safety requirements and a ban of the refrigerant R22 as of 2021. Regulations for electronic waste are currently being developed [1]. The remainder of this paper is structured as follows: The “Literature Review: Regulating Material Use vs Energy Efficiency and Carbon Footprint?” section summarizes existing regulatory approaches and reviews available lifecycle assessment and footprint literature, followed by a section on the methods employed in the study (“Methodology” section). The “Results and Discussion: Business Models in the Second Hand AC Market in Metro Manila” section presents and discusses the results on the AC market in Metro Manila, analysing business types and competition, sources of ACs and middlemen, AC types and prices, customers and their purchase motivations as well as insights on energy efficiency and refrigerant handling. Finally, policy recommendations for green and social regulation of the second hand AC market and conclusions for future research will be drawn. Literature Review: Regulating Material Use vs Energy Efficiency andCarbon Footprint? The challenge in regulating the used AC market lies in, first, finding most suitable combination of measures to phase-out inefficient, climate-harmful devices without increasing material resource use and waste and without jeopardizing social livelihoods, and, second, in finding the most suitable point in time for intervening in the product lifecycle. This section summarizes the existing regulatory approaches to the reuse of appliances and end- of-life management as well as the technical information provided by the available lifecycle assessments (LCA) for ACs. From the latter, theoretical environmental policy options (green goals) can be derived. The empirical analysis in the remaining sections then focuses on the functioning of the second hand AC market and potential regulatory impacts on livelihoods (social goals). Regarding the most suitable combination of measures, the specific balancing challenges for used ACs has not been completely recognized yet by policymakers. Two challenges for used electronic appliances have been identified in general [23]: First, the methodological question how to best assess the reusability of appliances in terms of the many environmental, social, legal, technical and cultural factors is still open. Second, comparative information and functionality tests are lacking. Consumers would need to be able to compare the functionality, energy efficiency and resource footprint of a used product to an available new product. Recyclers require more information on component structure and durability. However, economically feasible functionality tests of used appliances and labelling after testing are lacking. In many countries, the reuse of appliances features in waste management regulations which are part of WEEE policy packages, for example, in the EU and China. As the reuse of white goods and private resales often happen without policy incentives and a range of product lifetime extension models exist already [10, 23], second hand markets do not necessarily require regulation for all types of goods. In the EU, reuse in WEEE policies is part 794 Circular Economy and Sustainability (2023) 3:791–810 1 3 of a broader recyclingpolicy package. This emphasis on recycling may lead to a neglect of developing and implementing specific repair and reuse standards by member states [29]. Lu etal. [23] also argue that the ambiguity of terminology and insufficient appreciation of product/component reclamation over recycling hamper existing WEEE policy effectiveness in the EU. In China, in turn, reuse of appliances and components is popular without policy support [23]. To the author’s knowledge, there are no specific regulatory approaches aimed at reusing ACs, e.g. the time a used AC should remain in the market or the repair standards it has to fulfil. Table1 provides an overview of the main regulatory approaches relevant for used ACs, even if these mostly target the end-of-life stage or electronic waste more generally, without specifically targeting ACs. As reuse of components and remanufacturing happens a lot more in low- and middleincome countries than in high-income, industrialized countries, a different combination of policy measures and managements systems may be required [23]. Furthermore, the current political focus on phasing-in new energy efficient appliances often comes with the expectation of a swift trickle-down effect, pushing old, inefficient appliances out of the market [25]. This process may, however, be much slower than policymakers expect, given that second hand markets present a blackbox at this stage. Extended producer responsibility (EPR) schemes are being discussed and implemented in many low- and middle-income countries as a key approach for WEEE. However, the reduction of waste upstream by explicitly including quality standards for used goods and/ or standard reuse procedures (preparation, dismantling, transfer, disposal, sales) presents a gap in most existing EPR schemes [6]. In the EU, general reuse standards laid out in the 2012 WEEE directive do not integrate well with EPR schemes [23]. Current take-back regulations of e-waste can be differentiated into those without reuse targets, aiming only at collection, and those with reuse targets, aiming at both collection and reuse [8]. Higher reuse targets may benefit consumers if there is competition in remanufacturing in a regulated market [8]. Additionally, the various actors involved in the reuse and end-of-life chain such as producer organisations and collectors may have opposing interests and lack communication, as first studies in European countries have shown [6]. In low- and middleincome countries, the functioning of the used AC markets, actor composition and interests as well as the current levels of repair, reuse, energy efficiency and climate impacts are still unclear. This makes the identification of regulatory starting points difficult. In the Philippines, neither an EPR scheme nor standardized collection or reuse targets have been set at this stage. The import of second hand electronics requires a permission by the Department of Environment and Natural Resources (DENR), but the sector is overall not well regulated yet [34]. The Republic Act 6969 sets out regulations on the importation, manufacture, processing, handling, storage, transportation, sale, distribution, use and disposal of chemical substances and mixtures that present unreasonable risk and/or injury to human health or to the environment in accordance with national policies and international commitments. This includes refrigerants of ACs. Companies importing ACs and handling refrigerant disposal need to register with the DENR. Two specific administrative orders by DENR provide procedures for the handling of hazardous waste and WEEE. Household white goods shall be consolidated by Material Recovery Facilities; specific guidelines and precautionary measures for the registered facilities treating and disposing WEEE for environmentally sound management exist (DAO 2012–22). At the time of data collection for this study, the regulatory framework for e-waste, including ACs, was being re-evaluated and updated, including a potential combination with an F-Gas regulation and phase-out schedule in line with the Montreal Protocol. To the authors’ knowledge, no final new legislation or administrative orders have been published till the time of writing; depicting trends 795 Circular Economy and Sustainability (2023) 3:791–810 1 3 Table 1 Overview of main electronic waste and F-gas regulatory approaches relevant for ACs *Other countries ban the import of used electronic waste without specifying ACs.

The government entities contacted during the course of this study were particularly interested in understanding the used AC market, being fully aware that current regulation does not reach this market (see the “Methodology” section). No specific, reliable data on the number of used, reused and disposed ACs in the Philippines is available at this stage. For ACs, a combination of measures may be required that support the reuse of metals and non-hazardous components of the AC, but the phase-out of inefficient complete ACs or harmful parts such as chemicals and refrigerants. The latter requires a set-up of a collection system and management of ozone depleting substances (ODS) banks which are missing in many countries this far, including the Philippines [13]. LCA provide the technical background to guide a prioritization of measures for used ACs from an environmental perspective. There are no LCA for residential ACs in the Philippines available that include repair and reuse, which are necessary to understand both first and second hand market impacts. Available LCA for other middle-income countries such as China, Indonesia and India have found that energy and climate impacts are highest during the use stage of the AC, not during manufacturing, transport or sales [14, 19, 35]. This is primarily due to the share of fossil fuels in the electricity mix, confirming the findings of LCA in the USA [22, 30]. Importantly, not only the user behaviour itself (e.g. active use duration, leaving the AC on when not in the room), but also the electricity required to keep the refrigerant cool, while the unit is idle contribute up to a third of the lifecycle emissions in hot countries [28]. In European countries, a switch to a renewable energy mix would decrease the global warming impact of household appliances, including ACs, by 25% [17]. However, this scenario would not reduce appliance use impact on ozone depleting substances, as these would continue to be used in ACs in such a single shift scenario. Steel and copper have the greatest influence on environmental resource footprint during AC manufacturing [3]. For Indonesia, a country comparable to the Philippines in terms of electricity mix and market structure, Karkour etal. [19] confirm that the use stage of ACs has the highest global warming potential due to electricity use (90%), which are also higher than direct emissions from refrigerant leakage. Copper and nickel are found to be responsible for the largest share of resource consumption impacts (50%) and also have the highest price due to being more scarce than iron, for instance. Looking at AC parts in more detail, the compressor and the heat exchanger (copper and iron) make up the largest share of the resource footprint [19]. For a potential regulation of used ACs, these findings imply that energy and climate goals prevail over resource footprint concerns (unless copper and nickel become scarce). To identify the most suitable point in time in the lifespan to intervene, assessments of the emissions and electricity consumed during AC manufacturing need to be balanced with prolonged lifetime impacts. As Nishijima [26] shows for Japan, shortening the life time of ACs by 1year to maintain the carbon emission levels of 1990 requires a stricter strengthening of minimum energy performance standards (+ 20.6%) than setting incentives to prolong AC possession by 1year (standards strengthened by + 17.8%)—with the same result. The choice of political measure depends on what the local AC industry can realistically achieve. Minimizing energy consumption requires more frequent replacement of residential central ACs over time than minimizing greenhouse gas emissions [7]. Additionally, the impacts of repair and replacement of parts as well as differences in electricity use intensity, especially for inverters, according to run time, temperature setting and cleanliness need to be taken into account. A more in-depth study of the amount of waste and recycling flows would be required, given that not all parts of an AC can be 797 Circular Economy and Sustainability (2023) 3:791–810 1 3 recycled and environmentally ideal waste and recycling systems may not (yet) exist. While Karkour etal. [19] recommend to recycle used units as quickly as possible, the identification of a concrete, suitable point in time for intervening in the lifecycle of used ACs is still not straightforward. Regarding environmental costs vs human benefits, the authors found that the share of materials costs are lowest during a 10-year lifespan (1–3% of costs only). The inverter-type AC has the highest benefits, mainly due its low impact in the use phase. In sum, the current literature suggests that a combination of repair and reuse standards for used ACs, reuse targets and collection processes for precious metals such as copper and nickel as well as the management of ODS-banks would be useful. From an environmental perspective, prioritizing energy and climate goals means intervening in the used AC market to stop inefficient, repaired models to circulate for too long, i.e. more than 10years, possibly even shorter. Limiting the lifetime of ACs (new and reused) may need to be strategically combined with tightening MEPS for ACs. These theoretical options now need to be put into the empirical context of the second hand AC market in Metro Manila. In addition to technical and environmental factors, questions of affordability and access to cooling as well as the livelihoods connected to the business need to be considered to derive a suitable regulatory approach. Methodology The goal of this study is to assess options, potential impacts and acceptance of regulating the second hand AC market, with an empirical focus on socioeconomic aspects in the market. To assess these, quantitative modelling of environmental impacts or of general regulations on unknown market structures are hardly suitable. Rather, as a first step, a qualitative understanding of the market, its functioning, the stakeholders and their interests and interactions is required. Conceptually, the analysis draws on studies on micro and small enterprise development and informal markets in developing countries (e.g. [2,11,16, 24], taking a broad business model lens. Key elements of such formal and semi-formal market analyses involving micro and small enterprises typically include an assessment of firm characteristics (e.g. business size, informality/registration and sales/turnover), entrepreneurial characteristics (e.g. education, skills) and the business environment (e.g. access to resources, business practices, competitive advantage). This analytical lens as well as the insights of LCA for ACs summarized in the previous section serve as starting points for the empirical analysis of the current second hand market for ACs in Metro Manila. Whereas a deeper technical assessment is not the core interest of this study, reported energy efficiency of the units found in the second hand market, energy saving considerations as well as repair and refrigerantrelated practices by technicians and consumers will be taken into account. These indicate the general level of environmental impact of current practices. Methodologically, this study takes an inductive, qualitative approach. A content analysis following Mayring (2003) was conducted on policies, background materials and qualitative interviews. In March 2020, 10 background interviews with experts, business organisations, international donor agencies and members of government were conducted in Metro Manila. The list of institutions interviewed is provided in the Annex. At the end of each interview, each expert interviewed was asked to recommend other people in the field to further discuss the matters (snowballing technique). Due to the outbreak of the COVID-19 798 Circular Economy and Sustainability (2023) 3:791–810 1 3 pandemic in March 2021, complete saturation was not reached as three further expert interviews had to be cancelled (see Annex). Subsequently, 29 semi-structured interviews with second hand retailers and technician-retailers were conducted throughout Metro Manila until end of November 2020. The background interviews served to understand the current state of information and the policymaker view on the topic. Policymakers were aware of some shop locations and rough prices for second hand units, but had no in-depth knowledge how the business and supply chain in the second hand market works. The role of energy efficiency as well as current repair practices and refrigerant leakage was also largely unknown, but deemed relevant for future policymaking. Additionally, the background interviews were used to refine the semistructure for the interviews with retailers and technician-retailers. The semi-structured interviews finally included questions on the business type and firm characteristics; sources and types of ACs sold; customers and sales; competitors, competitive advantage and market functioning; energy efficiency/energy saving awareness, refrigerant and repair practices (relating to both entrepreneur skills and customer interest). Finally, compliance with current regulations and opinions on potential regulation of the used AC market and acceptance of public or private intervention were sought, e.g. via an extended producer responsibility (EPR, explained in easy wording). The interviews were partly conducted in English, partly in the local language Tagalog with the help of a local consultant, and translated to English. Given the sensitivity of some of the topics addressed (e.g. bribery, non-payment of taxes), we refrained from recording and took notes only. Respondents were assured that their answers remain anonymous; statements are therefore mainly summarized and interview quotes attributed to a randomized numbering of interviews. Interview notes were coded and analysed using atlas.ti. Results andDiscussion: Business Models intheSecond Hand AC Market inMetro Manila Business Types andCompetition The market for second hand ACs in Metro Manila is primarily situated in the semi-formal and informal sectors. Semi-formal sector here is defined as follows: The AC technician belongs to a larger, registered business, but sells second hand ACs informally; or the micro or small enterprise is registered, but does not pay all taxes; or it is only registered with the Department of Trade and Industry (DTI), but not the local government unit (LGU). Several fully formal, registered AC enterprises engage in the second hand market as well. The businesses in the second hand market are micro and small enterprises, ranging from an individual technician to a small enterprise with 1–7 staff members. Staff are often family members, but also hired labourers or sub-contracted technicians for fixed time periods. Only one enterprise interviewed can count as a medium-sized enterprise with 80 staff during peak season, composed of both trained technicians and unskilled labourers. The used AC business is very seasonal with substantially more and faster sales during the hot season in Metro Manila (February/March till end of May) than in the cooler or rainy months. During the low periods for sales of second hand units, maintenance and repair services become more important for most enterprises and individual technicians. Most of the second hand shops or individual technician-retailers maintain several lines of business. Services offered include buying and selling of second hand ACs and its parts, 805 Circular Economy and Sustainability (2023) 3:791–810 1 3 Those retailers and retailer-technicians who do not comply believe that the government will never have enough technical inspectors and financial means to control (e.g. interview 21, November 25; interview 32, October 29; 2020). Among most interviewees, trust in government in general and in service delivery by sub-agencies is rather low. The vast majority of respondents favours not only a continued, but also more protected second hand market if the government in turn reliably offered more supportive services, e.g. micro-finance or financial incentives for energy efficient technology replacement. For balancing energy and climate goals in the second hand AC market with material and social goals, these findings imply that a quick phase-out of inefficient ACs or at least efforts to improve energy efficiency, refrigerant disposal and repair standards are required. An established, easy to use system for ODS/refrigerant disposal is required that can become standard practice for retailers and technicians. Additionally, continued awareness raising for customers on cost-benefits including energy efficiency and climate harmful substances in used units as well as the limits of used inverter ACs is necessary (Fig.1). Repairing andEnd Of life Repair practices and quality are important to estimate environmental impacts and socioeconomic factors for the decision how to regulate the second hand market. Generally, AC technicians and second hand dealers interviewed repair and reuse all the materials possible. The technicians take out the copper wires, other metals such as nickel and useable parts including compressors to re-use and refurbish as much as possible. The plastic parts often cannot be reused and are taken to the landfill or junkyards close by. The majority of enterprises and technicians interviewed assemble and sell “new” units from various scrapped ACs, parts acquired over time and—less so—from a mix of used and new parts. Some enterprises also offer repair services for other appliances such as washing machines or rewind motors. A few technician-retailers are specialized in selling used compressors and other used parts of ACs. These results confirm Alam’s [1] findings on the end-of-life stage of ACs in other Philippine cities. The type and brand of an AC matters for the extent to which it becomes a resource for reuse. For repair and reuse purposes, window-type room ACs are preferred as they are generally said to have more durable parts than split-type and inverter ACs Fig. 1 Schematic diagram of the second hand AC market in Metro Manila. Source: Author 806 Circular Economy and Sustainability (2023) 3:791–810 1 3 (interview 9, March 9; interview 10, March 4; interview 13, March). Therefore, fewer inverter ACs are available in the scrap/reuse market. Panasonic ACs, especially inverters, can hardly be found at all—neither as second hand unit nor as scrap item that can dismantled and parts reused. New, first hand Panasonic ACs count as particularly durable, lasting approximately 10years in primary use—“but after this time, the parts are so worn out that they cannot be reused at all” (interview 10, March 4, 2020). Some AC parts are interchangeable across specific brands such as Carrier and Koppel, making these models and their parts particularly popular among technicians and retailers. The repair and reuse procedures can include some questionable practices. The restoration of old units or assembly from parts may include an “upgrading” to a higher class model, i.e. a class B unit is then sold as a class A model, or a used unit is sold as a completely new one. Some shops or technicians-retailers clean and polish the used ACs and wrap them in plastic to make them appear new. The customer usually cannot tell the difference. A few technicians-second hand dealers are specialized in selling used compressors and refurbishing compressors and/or ACs, either sell the compressor or a whole refurbished AC unit. This may include re-branding, putting false serial numbers and polishing/re-packaging the AC to sell at a higher price. Once parts of ACs are deemed unusable or invaluable by retailers and technicianretailers, either scrap dealers pick up or receive the remaining parts, or the retailers bring them to junkyards or landfills. For the (informal) scrap dealers, copper and nickel as well as other metals present the most precious parts of an AC. These are usually dismantled or scraped out manually as even the larger enterprises lack the appropriate machinery for this kind of waste separation and recycling. Larger scrap dealers and wholesalers attend governmental auctions, for instance, in Valenzuela City and Mandaluyong City (both part of Metro Manila). When they buy scrap from technicians or second hand dealers, they sell the metals on to the smelting plants situated on the outskirts of Metro Manila. Only few LGU have recycling sites for materials in Metro Manila and hardly any formally registered companies operate for ACs. There is only one accredited collection, transport and storage facility that can handle climate-damaging refrigerants. Additionally, some recycling sites in key industry areas and in the special economic zones with a more established system for hazardous waste exist. Existing drop-off stations for e-waste focus on smaller appliances this far, as do the public and civil society initiatives and campaigns active in the field this far. Here, a significant policy gap exists. Among the retailers and technician interviewees, the idea of establishing an EPR system for ACs resonated well as long as it is run by private actors, as trust in governmental agencies to pay is low (interview 10, March 4; interview 22, March 12, 2020). For retailers and technicians, incentives or alternative sources of income via the integration in an EPR are likely more feasible than integrating informal recyclers and scrap dealers (market pull factors). In terms of the material impact of the used AC market, our findings imply a high degree of informal circularity for compressors, metals and to some extent fans and valves. This finding questions the necessity of a short-term regulatory intervention in the market. However, repair and reuse practices are not environmentally friendly in those cases in which refrigerants are vented and used oils not disposed of properly. For plastic parts and inverter units, the material life in the second hand market ends more quickly and is likely harmful for the environment. For the end-of-life management of ACs, accessing and managing informal scrap dealers present a particular 807 Circular Economy and Sustainability (2023) 3:791–810 1 3 challenge. Moreover, more facilities and a more structured system for recycling of materials and refrigerants are required. Conclusion andPolicy Implications The balancing of energy, climate, materials resource and social aspects in the second hand AC market requires the appropriate timing and combination of measures. Overall, the improvement of second hand AC quality, including repair and reuse of ACs, to foster more positive development effects in line with a circular economy approach is desirable. The exact point in time in the lifecycle of an AC at which environmental and social costs and benefits are on par is difficult to identify without deeper technical analyses of AC units in the Philippine second market. The analysis has shown that short- to mid-term regulations and interventions are more appropriate than postponing to the long term or foregoing any regulation. From an energy and climate perspective, phasing-out used ACs as quickly as possible is desirable; from a social and waste management perspective, allowing for a short prolongation of an AC life by approximately 1–3years is more attractive than no affordable ACs and lost jobs. Ideally, all very old AC units, for example, those entering the used AC market for a second time or broken units with more than 3–5years added lifetime after primary use (i.e. 8–10years), should be phased out quickly. The following policy options could be explored, categorized along the well-known “stick-carrot-tanmbourine” categories of energy policy: • Ban second hand market (“stick”): not useful because (a) resource waste/waste problem likely to increase as no complete, professionally organized disposal/recycling system in place yet, (b) this would deprive many Filipinos of access to an affordable cooling device; (c) employment/livelihoods in the market would be quite strongly affected as a substantial part (min. 10–30%)of income for both individual technicians and SMEs active in the sector would be cut; (d) second hand market would only become completely clandestine then. • Regulate construction industry and building demolition (“stick”): Change building code/demolition and waste regulation to (a) enforce AC and refrigerant disposal as hazardous waste, (b) set fines for middlemen who do not comply, and (c) develop and set clear conditions which used AC units can enter the second hand market (e.g. based on age, type and horsepower of unit, refrigerant) and which used ACs are banned from any reuse. For example, it could be debated whether units with a lot of horsepower or suitable for large rooms need to be available at affordable prices (as poorer households usually do not have many or very large rooms that need cooling). • Set-up of professional reuse and recycling scheme that integrates the second hand market (“carrot and tambourine”, see Streicher-Porte/Gerring [32] for a similar suggestion for white goods in China): This would require more specific electronic waste regulation and the development of an EPR scheme, possibly complemented by a used AC rebate scheme for consumers, technicians and scrap dealers to hand in least efficient ACs. Technicians and retailer-technicians signalled general openness if an EPR scheme was privately run (low trust towards government agencies). 808 Circular Economy and Sustainability (2023) 3:791–810 1 3 • Gradual set-up of repair standards for consumer and technician information (“tambourine”), as suggested in the WEEE literature for other white goods (e.g. [23]: A gradual process with a voluntary process to ensure buy-in of all stakeholders is advisable. Starting points could be a competition and public award for the most energy efficient, climate friendly, repaired AC or designing a behaviour change intervention aimed at technicians and technician-retailers’ pride, trust and system of reciprocity to self-establish a repair standard. • Establish green credit lines and energy advisory services for SMEs/small service industry (“carrot”) to incentivize and enable these enterprises to buy new ACs and refrain from perceived bargains of used ACs, as especially owners of small restaurants, bars and other SMEs buy second hand ACs in the Philippines.
