Summary
This policy-focused analysis establishes a preliminary global mitigation target of ~1 Gt CO₂e per year by 2030 for agricultural greenhouse gases necessary to limit warming to 2°C. The authors find that plausible agricultural development pathways with co-benefits deliver substantially less mitigation than needed (21-40%), indicating that more transformative technical and policy interventions—including methane inhibitors and financial support for new practices—are required. The work emphasises that excluding agriculture from climate mitigation targets increases overall mitigation costs and reduces feasibility of meeting the Paris Agreement goals.
UK applicability
UK agriculture accounts for approximately 10% of national GHG emissions, primarily from livestock and soil management. These findings suggest UK agricultural policy must move beyond incremental improvements in efficiency to adopt more transformative practices and technologies to contribute proportionally to global mitigation targets, particularly in the ruminant livestock and dairy sectors.
Key measures
Global agricultural GHG emissions reduction target (Gt CO₂e yr⁻¹); percentage of mitigation potential delivered by plausible development pathways; sectoral cost implications
Outcomes reported
The study identified a preliminary global target for reducing agricultural GHG emissions of approximately 1 Gt CO₂e per year by 2030 to limit warming to 2°C above pre-industrial levels. It assessed the feasibility of plausible agricultural development pathways and found they deliver only 21-40% of the mitigation needed to meet this target.
