The City of Stockholm aims to achieve net-zero emissions by 2030 compensating for residual using bioenergy with carbon capture and storage (BECCS). Relying heavily on negative reach the target, city's strategy presents an interesting case climate policymaking. Based analysis interviews, Council debates, policy documents, underscores importance understanding municipal in a multi-level setting, where ability govern varies between sectors depending politics at other levels governance. Both waste incineration road transport are perceived include hard-to-abate 2030, partly due governance linkages involving regional, national, EU-level governing bodies. energy utility, Exergi, plans implement BECCS, funding from EU public private sources, heat power plant. unique opportunity use BECCS as part target has made it possible advance goal 2040 2030. However, there risks that relying may muffle debate what constitutes city, subsequently leading smaller investments emission reductions. Additionally, schedule implementing is overly optimistic, meaning fulfilment be threatened. this risk not isolated BECCS; similar associated combining fossil fuels CCS. We recommend city critically examines emissions, considers separate targets instead goal, conducts assessments key mitigation technologies maintain its status forerunner.

Deployment expectations of multi-gigatonne scale carbon removal could have adverse impacts on Asia’s energy-water-land nexus

Abstract Existing studies indicate that future global carbon dioxide (CO 2 ) removal (CDR) efforts could largely be concentrated in Asia. However, there is limited understanding of how individual Asian countries and regions will respond to varying uncertain scales CDR concerning their energy-land-water system. We address this gap by modeling various levels CDR-reliant pathways under climate change ambitions find high reliance leads residual fossil fuel industry emissions about 8 Gigatonnes CO yr −1 (GtCO 2050, compared less than 1 GtCO moderate-to-low reliance. Moreover, expectations multi-gigatonne delay the achievement domestic net zero for several regions, lead higher land allocation fertilizer demand bioenergy crop cultivation. Here, we show should prioritize emission reduction strategies while capitalizing on advantages when it most viable.

Carbon dioxide removal: A source of ambition or of delays? Examining expectations for CDR in Swiss climate policy

Environmental Science & Policy, Год журнала: 2024, Номер 153, С. 103659 - 103659

Carbon dioxide removal (CDR) is recognized as an important tool for addressing residual emissions and achieving net-zero emission targets. While some have cautioned that a focus on CDR in policy processes may lead to delayed efforts mitigate emissions, others argued such concerns are unwarranted. Nevertheless, the circumstances under which could help or delay mitigation given contexts remain unclear. This paper explores emerging discourse Switzerland. We examined how community legitimizes limits its scope, what implications mitigation. Switzerland home growing businesses has pioneered implementation of international offsetting projects Article 6.2 Paris Agreement. found numerous promises legitimize attract interest CDR. Actors use discursive strategies rules limit avoid disappointment contribution climate The idea reduction should prevail over promoted accordingly, ironically helps yet dodges question much possible balancing emissions. Superficial engagement with issue reinforced by normalization inflated sentiment deterrence rhetoric erodes trust argue this can contribute delays evading debate it remove taking resources from alternative measures. recommend thorough discussion examine risks minimize them.

Whose negative emissions? Exploring emergent perspectives on CDR from the EU's hard to abate and fossil industries

Net zero targets have rapidly become the guiding principle of climate policy, implying use carbon dioxide removal (CDR) to compensate for residual emissions. At same time, extent (future) emissions and their distribution between economic sectors activities has so far received little attention from a social science perspective. This constitutes research gap as corresponding amounts required CDR is likely highly contested in political economy low-carbon transformation. Here, we investigate what function performs perspective considered account large proportion future (cement, steel, chemicals, aviation) well oil gas industry EU. We also explore whether they claim be compensated outside sector, quantify these claims how justify them. Relying on interpretative qualitative analysis, decarbonization or net roadmaps published by major sector-level European trade associations statements public consultation submissions reaction policy initiatives EU mobilize CDR. Our findings indicate that while technologies perform an important abstract reaching roadmaps, responsibilities delivering levels negative remain largely unspecified. risks eliding pending distributional conflicts over which may intersect with diverging technological transition pathways advocated associations.

Residual emissions in long-term national climate strategies show limited climate ambition

One Earth, Год журнала: 2024, Номер 7(5), С. 867 - 884

Net-zero targets imply a need to compensate for residual emissions through the deployment of carbon dioxide removal methods. Yet extent within national climate plans, alongside their distribution, is largely unexplored. Here, we analyze 71 long-term strategies understand how governments engage with emissions. Screening 139 scenarios, determined that only 26 quantify Residual are on average 21% peak Annex I countries, ranging from 5% 52% (excluding land use). For non-Annex 34%. By sector, agriculture represents largest contributor total (on average, 36% countries and 35% countries). High-residual-emission scenarios show some may retain or expand fossil fuel production use, using more international offsets achieve net zero.
