The Global Methane Status Report 2025 examines progress in reducing methane and the gap between existing action and the Global Methane Pledge. UNEP and the Climate and Clean Air Coalition released it on 17 November 2025 during COP30 in Belém, Brazil.
Its central message is a distinction between an improving outlook and an achieved decline. Global methane emissions were still rising, even though projected future emissions had fallen relative to earlier forecasts. A lower projection is progress in expectations; it is not necessarily a reduction in emissions already entering the atmosphere.
What the headline numbers mean
| Measure in the report | Meaning |
|---|---|
| 30 per cent below 2020 by 2030 | The collective Global Methane Pledge objective |
| About 8 per cent below 2020 by 2030 | Potential outcome if national pledges and action plans submitted by mid-2025 are fully implemented |
| 72 per cent from energy, 18 per cent from waste and 10 per cent from agriculture | Shares of the assessed mitigation potential, not shares of all methane emitted |
These estimates describe specified scenarios and assumptions. They should not be quoted as an observed 8 per cent global reduction or as proof that agriculture causes only 10 per cent of emissions.
Why methane deserves separate attention
Methane is a greenhouse gas with a strong warming effect and a much shorter atmospheric lifetime than carbon dioxide. Reducing it can influence near-term warming, while sustained carbon-dioxide reductions remain necessary for long-term climate stabilisation.
Human-caused sources include fossil-fuel operations, agriculture and waste. Natural sources also exist, so an estimate of anthropogenic emissions should not be silently relabelled as all methane from every source.
Three further quantities need separation: emissions are the flow released during a period; atmospheric concentration is the amount present in the air; mitigation is the reduction attributable to an action compared with a defined baseline. They answer different questions.
Energy-sector measures
Oil and gas systems can release methane through leaks, venting and other operational sources. Coal extraction can also release methane trapped in coal-bearing formations. Measurement helps identify which facilities and processes require attention.
Leak detection must be followed by repair and a subsequent check. Recording that a team visited a facility is not equivalent to proving that its emissions fell. Responsibility for maintenance and the cost of repeated monitoring should be built into implementation.
The IEA’s methane-tracking work combines information from different measurement approaches and identifies uncertainty, including gaps around abandoned infrastructure. Better data may revise earlier estimates upward without proving that all of the apparent increase happened during the latest year.
Agriculture requires a livelihood-sensitive approach
FAO explains that ruminants produce methane during microbial digestion, known as enteric fermentation. Manure management is another source. Improved nutrition, animal health and suitable husbandry can be part of mitigation, but farmers need access to advice, services and viable incentives.
Emissions per litre of milk and total emissions are different indicators. If each litre requires fewer emissions but production expands substantially, total emissions may still rise. Reporting both avoids presenting an efficiency improvement as an automatic absolute reduction.
Rice cultivation also presents opportunities through appropriate water management. Practices must suit soil, water control and crop conditions. A climate programme that assumes every farmer can independently control irrigation will struggle where water is supplied through a shared schedule.
Waste systems can prevent avoidable methane
Organic material can generate methane as it decomposes without oxygen. Keeping food and other wet waste separate creates options for suitable biological processing instead of allowing mixed waste to accumulate unmanaged.
Biogas recovery needs reliable operation and control of leakage. Installing a digester without maintaining gas collection can undermine the intended climate benefit. This connects methane policy with urban waste segregation and processing.
Finance and verification
A credible project specifies its baseline, technology, responsible operator and monitoring method. It should distinguish estimated engineering potential from reductions demonstrated during operation. Independent checks are especially useful where payments depend on claimed performance.
For India, the policy discussion should account for differences between industrial facilities, local bodies and smallholder farms. The same reporting burden or financing arrangement may not work for all three. Grouping small participants and supporting shared services can make implementation more practical.
Questions for revision
1. Did the report say methane emissions had already fallen by 8 per cent?
No. That figure is a conditional projection tied to implementation of specified national commitments and plans.
2. Are methane cuts a substitute for reducing carbon dioxide?
No. They address an important part of near-term warming but do not remove the need to reduce long-lived greenhouse-gas emissions.
3. What is the main exam trap?
Confusing present emissions, future projections and mitigation potential. Always state the baseline year, target year, scope and condition attached to a reported percentage.
