Integrating Carbon Dioxide Removal Into European Emissions Trading

Frontiers in Climate, Год журнала: 2021, Номер 3

Опубликована: Июнь 24, 2021

In one of the central scenarios for meeting an European Union-wide net zero greenhouse gas (GHG) emissions target by 2050, cap in Union Emissions Trading System (EU ETS) becomes negative. Despite this ambition, no mechanism allows inclusion CO 2 removal credits (CRCs) EU ETS to date. Amending legislation is required create enabling conditions a negative cap. Here, we conceptually discuss various economic, legal, and political challenges surrounding integration CRCs into ETS. To analyze cap-and-trade systems encompassing emissions, introduce effective (elastic) resulting from addition regulatory (inelastic) cap, latter now being binding only. Given current cost estimates BECCS DACCS, minimum quantities use removals, as opposed ceilings currently discussed, would be promote near-term such technologies. Instead direct interaction between companies involved trading providers CRCs, authority could also transitionally act intermediary buying supplying them turn conditional upon observed allowances prices, example, supporting (soft) price collar. Contrary collar without dedicated support case (net) compliance with overall maintained. already provides safeguards physical carbon leakage concerning CCS, making Bioenergy Carbon Capture Storage (BECCS) Direct Air prioritized Furthermore, special opportunity might apply installations. Repealing provision that installations exclusively using biomass are not covered Directive, combined freely allocated these installations, allow operators sell made available through BECCS. Achieving GHG neutrality 2050 requires designing suitable incentive removal, which includes option open up CRCs.

Energy and food security implications of transitioning synthetic nitrogen fertilizers to net-zero emissions

Environmental Research Letters, Год журнала: 2022, Номер 18(1), С. 014008 - 014008

Abstract By synthetically producing nitrogen fertilizers from ammonia (NH 3 ), the Haber–Bosch process has been feeding humanity for more than one hundred years. However, current NH production relies on fossil fuels, and is energy carbon intensive. This commits to emissions levels not compatible with climate goals agricultural fuels dependency. Here, we quantify food implications of transitioning net-zero CO 2 emissions. We find that 1.07 billion people are fed produced imported fertilizers. An additional 710 million natural gas feedstocks used production, meaning 1.78 per year imports either or gas. These findings highlight reliance global trading hence its vulnerability supply shocks. alternative routes achieve in exist, which based capture storage, electrification, biomass. comply targets while mitigating risks associated security. Yet, they require land, energy, water business-as-usual exacerbating land scarcity use limited resources. Transitioning can contribute security goals, although water, trade-offs should be considered.

A comparative analysis of the efficiency, timing, and permanence of CO₂ removal pathways

Energy & Environmental Science, Год журнала: 2022, Номер 15(10), С. 4389 - 4403

Опубликована: Янв. 1, 2022

Carbon dioxide removal (CDR) is essential to deliver the climate objectives of Paris Agreement. Whilst several CDR pathways have been identified, they vary significantly in terms CO 2 efficiency, timing, and permanence.
