Year-to-date through May, total global emissions stand at 25.3 billion tonnes CO2e, unchanged from the same period in 2025. Manufacturing emissions fell 1.5% year over year, the largest sectoral decline in absolute terms. Against those declines, power sector emissions rose 0.9%, building emissions rose 1.6%, and methane emissions, measured separately, rose 0.1% to 34.2 million tonnes of CH4 in May 2026 alone. Manufacturing’s Decline and What It ReflectsThe 1.5% fall in manufacturing emissions is the most structurally significant positive signal in the May 2026 sectoral data, but it requires contextualisation. The Global Methane Pledge, signed by over 150 countries at COP26, committed to a 30% reduction in methane emissions by 2030 from 2020 levels.
