1. In oduc ion
Food sys ems we e esponsible o abou one- hi d o global an h opogenic g eenhouse gas

deca boniza ion o o he sec o s. An ambi ious and e ec i e clima e policy, he e o e, canno

indi ec ly cause p ema u e dea hs (Sp ingmann e al., 2023; Himics e al., 2022; Funke e al.
2022).
While he bulk o EU g eenhouse gas emissions is co e ed by he EU emission ading sys em
(including ag eed ex ensions o buildings and oad anspo ), p ice mechanisms emain la gely
absen in ag icul u e, which is co e ed unde he emission a ge s se by he E o Sha ing
Regula ion (ESR). One way o add ess his issue is o le e age p icing o accoun o
en i onmen al damages ela ed o ood consump ion. This idea is no no el, as i has been
discussed (e.g. in he EU Fa m o Fo k s a egy Eu opean Commission, 2020), s udied in policy
(EC, 2023) and academic con ex s (Klene e al., 2023), ecommended by he Eu opean
Scien i ic Ad iso y Boa d (ESABCC, 2024) and ecen ly p oposed o implemen a ion in
Denma k. One o he ad an ages o p ice-based policy measu es, as a ma ke -based ins umen ,
is in o ma ional e iciency: he p ice signal di ec ly ep esen s ex e nali ies, educing he need o
consume s and p oduce s o engage in ime-consuming assessmen s o sus ainabili y c i e ia o
compa ison o ecolabels. As such, p icing ins umen s can o m a s ong componen o a
b oade policy package (Sp ingmann e al., 2018).
Howe e , se e al conce ns s em om he adop ion o p ice measu es. One is he
compe i i eness o he EU ag icul u e sec o . In he absence o a la ge-scale in e na ional
coo dina ion o a ca bon bo de adjus men mechanism co e ing ag icul u e, g eenhouse gas

as om o eign p oduce s eplacing (g eene ) EU p oduce s in sa is ying domes ic and
in e na ional demand when EU p oduce s a e subjec o GHG emission axes while o eign ones

inc eases in o eign emissions. Finally, clima e-based ood p icing aises conce ns abou ai ness
as well. Food, in gene al, is a necessi y, and p ice inc eases could isk he accessibili y and
a o dabili y o ood, pa icula ly o households a he bo om end o he income dis ibu ion,
who ypically spend a compa ably highe sha e o hei budge on ood p oduc s (Klene e al.,

households, pe cei ed un ai ness o ax e o ms may hampe hei accep abili y (see Klene e
al., 2018 and Maes e-And es e al. 2019 o a discussion).

P ice measu es a ge ed o he demand-side based on consump ion axes migh alle ia e
compe i i eness and ca bon leakage conce ns as hey apply o all p oduc s consumed
domes ically, ega dless o hei o igin. Al hough demand-side measu es may ace challenges
simila o supply-side GHG p icing in e ms o dis ibu ional impac s, ea lie wo k has illus a ed

Pa icula ly, i has been a gued ha ‘ eeba es’ (blend o ee and eba e) migh be a cos -e ec i e

dis ibu ional impac s o ood p icing e o ms emains sca ce (see Klene , Funke and Cai 2023).
In his pape , we unde ake a wo- old analysis. Fi s ly, we p o ide a compa a i e assessmen o
equi alen demand-side and supply-side GHG p icing quan i ying hei impac on demand,
supply and emissions. We analyse he ex en o which subs i u ion e ec s ia in e na ional ade
as well as emission leakage shape he en i onmen al impac o di e en e o ms as well as hei

o a Value Added Tax (VAT) e o m designed o e lec he g eenhouse gas emissions. We
ega d his e o m ha le e ages exis ing VAT a es as a eal-wo ld, implemen able,

Ou key indings indica e ha he ha m o he EU ag icul u al sec o ’s compe i i eness and
ca bon leakage esul ing om supply-side p ice measu es would be signi ican unless hese
measu es a e widely adop ed in e na ionally. In pa icula , we es ima e ha an EU-only supply-

domes ic p oduc ion o all by abou one- hi d mo e han domes ic consump ion as o eign
p oduce s eplace EU ones. Mo eo e , gi en o eign p oduce s a e gene ally “less g een”, his
would come wi h a ca bon leakage amoun ing o 42% o he emissions educ ion achie ed in he
EU - hence se e ely us a ing i s clima e e o . By con as , ou p oposed VAT ax e o m can
econcile compe i i eness, clima e and equi y conce ns when combined wi h complemen a y
measu es. Indeed, since VAT equally applies o EU and o eign p oduce s selling in he EU, his
e o m would le el he play ield in he Single Ma ke and gene a e posi i e ca bon leakage. F om
an equi y s andpoin , while his measu e is eg essi e, a eeba e o equal-pe -capi a cash ans e

wel a e gains o he majo i y o he popula ion, while he op 20-30% o mea consume s
expe ience small wel a e losses. Howe e , ou esul s u he indica e ha VAT e o ms would
b ing a limi ed 2-3% educ ion in GHG emissions. Tha is because p oduce s shi ou pu o

Acco dingly, complemen a y ade measu es should be conside ed o enhance he en i onmen al
