Summary
The United Nations Environment Programme (UNEP) reports progress in methane mitigation since 2020, but achieving the 2030 Global Methane Pledge requires accelerated action. The pledge aims to cut methane emissions by 30% from 2020 levels by 2030. Tools, technologies, and data exist, and many reductions can be achieved with low-cost measures available today, though faster action is needed.
Key Points
- First comprehensive stocktake of global methane emissions since the 2030 Global Methane Pledge.
- The pledge targets a 30% reduction by 2030 relative to 2020 levels.
- Ruth Zugman do Coutto (UNEP) notes the pledge is still achievable and emphasizes the availability of low-cost reduction measures.
- Methane's impact: a potent greenhouse gas—about 30 times more effective at warming per unit than CO₂ over a 100-year period.
- Main human-caused sources: agriculture and livestock, natural gas, and landfills.
- Recent regulatory actions and pledges in Europe, North America, and other areas have helped lower projected emissions, despite overall rising trends.
“The global methane pledge is still achievable. We have the tools, technologies and data, and 80% of the reduction potential can be achieved through low cost measures available today, but we must accelerate action now.”
Context and Details
The report was publicized at COP30 in Belém, Brazil. Since 2020, progress on methane mitigation has been significant, though achieving the major international pledge’s goals will require additional action. The 2030 pledge was launched in 2021 as part of global efforts to curb methane emissions.
Implications
Continued policy tightening, regulatory measures on waste and industrial emissions, and expanded pledges could further reduce methane levels. While the emissions trajectory remains upward overall, targeted measures are gradually curbing growth and contributing to a potential decline.
