It attributes nearly 45% of current net warming to anthropogenic methane and emphasizes that rapid cuts this decade deliver larger near-term cooling than CO₂ mitigation alone. Without new action, emissions are projected to rise 5–13% by 2030, driven by increases in agriculture (especially livestock), fossil fuels (notably oil and gas), and waste, with coal roughly stable or declining. Regionally, Middle East/Africa and Asia see the largest growth. The Global Methane Pledge seeks at least a 30% reduction from 2020 by 2030, implying a 36% cut versus baseline and mitigation across all three sectors, with substantial health, crop, and economic co-benefits.
