This article draws from a database of asset-level emissions to identify key methane-emitting coal, oil and gas facilities in Southeast Asia while taking stock of the methane commitments of their owners. Coal mines account for around a third of fossil fuel methane emissions globally, but in Southeast Asia they make up more than half of tracked fossil fuel methane emissions. Over half of emissions from the coal mining subsector is traced to its top ten emitters, mostly in East Kalimantan, Indonesia; while some coal mines in North Vietnam have high emissions intensities. Though the global discourse on fossil methane focuses on oil and gas, coal mine methane remains crucial for Southeast Asia due to the region's lack of decisive coal phaseout plans. As countries begin to tackle coal emissions at the power generation stage, a gap still remains when it comes to coal mining emissions. Methane monitoring and abatement actions are urgently needed for coal mines that will continue to operate, as well as those slated for closure. More clarity is needed on how private sector commitments in the oil and gas sector will translate to action under complex and changing ownership arrangements. These gaps and uncertainties in methane abatement are ripe opportunities for closer partnership in the region, including within the private sector.
