The report explores the current emissions landscape across major oil and gas producing countries in the region, identifying gaps in data, monitoring, and regulatory frameworks. It highlights early progress made by national oil companies (NOCs) such as Pertamina, Petronas, and PTTEP, who are already piloting methane reduction technologies. Policy mapping reveals varying levels of readiness across ASEAN Member States (AMS), underscoring the need for stronger regional coordination. To support this, ACE introduces the “Hub for Innovative and Harmonized Methane Emissions Mitigation” (HORIZONS)—a new platform to centralise methane-related work, from research and data harmonisation to policy and financing. With practical recommendations and regional insights, this report aims to drive coordinated action and position methane mitigation as a key pillar of ASEAN’s energy transition.
