Methane abatement is crucial to safeguardingclimate goals and near-term meaningfulclimate action.Methane’s high global warmingpotential and short atmospheric lifespan makeit uniquely positioned to deliver rapid climatebenefits if addressed effectively. Achieving the1.5°C temperature goal requires a 45% reductionin global methane emissions by 2030. Globally, the agriculture, energy, and wastesectors dominate methane emissions, accountingfor 42%, 37%, and 19% of global emissions,respectively. The energy sector offers the highesttechnical abatement potential, particularly in theoil and gas sector where 77% of emissions can beabated with existing technologies. While actions at the national level areessential, methane abatement can alsobe accelerated through concerted effortsglobally.In the first instance, the identificationof common challenges and sharing best practicein the principal methane-emitting sectorswould accelerate the policy learning curve.Similarly, large emitting companies may sharesome commonalities and respond to similareconomic and policy levers, regardless oflocation. Secondly, initiatives can be taken atan international level to accelerate domesticpolicy actions, with domestic policy actions thatsupport abatement beyond national borders.This report covers all of those elements. Few countries dominate methane emissions,but global action is needed immediately.Seven countries account for half of all anthropogenic methane emissions, while thecoal sector in China alone accounts for 5% ofglobal emissions. Accelerating the policylearning curve: global lessonsfrom five archetypes Waste sector policy levers largely depend on the levelof development of the sector within each country, withsignificant cross-country similarity at each level ofdevelopment.The sector exhibits strong similarities acrossthe world due to the need to ultimately reduce organic wasteproduction, at all stages of supply chains, and the commonabatement technologies available for waste disposal. While every country’s methane abatement policy approachwill be different, there are commonalities that allow forpeer learning to accelerate abatement efforts.This reportidentifies five archetypes of specific national sectors with policylessons applicable for national sectors across the globe. The fivearchetypes are the coal sector in China, the agricultural sectorin India and in Brazil, the waste sector in Indonesia, and theoil and gas (O&G) sector for any O&G exporter. O&G exportersare grouped here due to their strong sectoral similarities andcommon political economy challenges. Embedding methane abatementin waste management: globallessons from Indonesia •Monitoring of waste sector emissions isfundamental to promote understanding ofabatement needs and enable enforcementof waste management regulations. Policy levers for abatement in agriculture demonstratethe greatest heterogeneity between countries,due to thehuge variability of agricultural systems around the world.Variation is seen between arable or pastoral farming dominance,livestock and crop types, predominance of smallholders or largeagribusiness, and technology uptake, both between countries,and within the same country. This is why two archetypes linkedto agriculture are included in the section below. •Waste methane targets are crucia
