Summary
This policy-oriented analysis establishes that agriculture must reduce emissions by approximately 1 Gt CO2e yr−1 by 2030 to support the 2 °C climate target, yet current plausible agricultural development pathways with co-benefits deliver only 21–40% of this needed mitigation. The authors argue that more transformative technical and policy interventions—including methane inhibitors and financing mechanisms—alongside comprehensive inclusion of soil carbon sequestration in climate targets, are essential to close the mitigation gap and maintain the feasibility of limiting global warming.
UK applicability
The UK is a signatory to the Paris Agreement and has legally binding agricultural emissions reduction targets; this analysis provides a framework for assessing whether UK agricultural mitigation pledges are aligned with global 2 °C pathways and identifies policy gaps (e.g., soil carbon accounting) relevant to UK climate strategy.
Key measures
Global agricultural GHG emissions reduction target (Gt CO2e yr−1 by 2030); percentage of mitigation achievable through plausible development pathways (21–40%); technical and policy mitigation options assessed
Outcomes reported
The study identified a preliminary global target of approximately 1 Gt CO2e yr−1 reduction in agricultural emissions by 2030 to limit warming to 2 °C, and assessed the feasibility of achieving this through plausible agricultural development pathways. It evaluated the gap between needed mitigation and what is technically and economically feasible under current development scenarios.
