Summary
This policy analysis establishes a preliminary global target of approximately 1 Gt CO₂e yr⁻¹ reduction from agricultural emissions by 2030 to support limiting warming to 2 °C above pre-industrial levels. The authors demonstrate that plausible agricultural development pathways incorporating mitigation co-benefits can deliver only 21–40% of the needed reductions, indicating that more transformative technical and policy interventions—including methane inhibitors and financial support for new practices—are essential. The work underscores that excluding agricultural emissions from global climate mitigation targets and plans will increase mitigation costs in other sectors or reduce the feasibility of meeting the 2 °C limit.
UK applicability
The global mitigation target and gap analysis are directly relevant to UK climate policy, particularly the Committee on Climate Change's sectoral emissions budgets and the UK Agriculture Bill. UK agricultural policy should consider how domestic emissions reductions contribute to this global imperative and whether current pathways are sufficient to meet UK domestic climate commitments whilst supporting international targets.
Key measures
Global greenhouse gas emissions reductions needed (Gt CO₂e yr⁻¹ by 2030); percentage of mitigation achievable through plausible agricultural development pathways with co-benefits (21–40%)
Outcomes reported
The study identified a preliminary global target of ~1 Gt CO₂e yr⁻¹ reduction needed from agriculture by 2030 to limit warming to 2 °C, and assessed the feasibility of plausible agricultural development pathways against this target.
