Indonesia Backs $20 Million South Korean Methane Initiative as Asia's Coal Rebound Complicates Climate Goals

Indonesia Backs $20 Million South Korean Methane Initiative as Asia's Coal Rebound Complicates Climate Goals The deal arrives as LNG disruptions push Japan and South Korea back toward coal, undermining the emissions reductions methane programmes aim to deliver. Indonesia has endorsed a $20 million methane mitigation initiative funded by South Korea, adding Southeast Asia's largest economy to a growing list of countries pledging to curb fugitive gas emissions. The programme targets methane leaks across Indonesia's oil and gas infrastructure, where flaring and venting remain widespread. The timing is pointed. Across Asia, the energy response to the Iran conflict has moved sharply in the opposite direction from methane reduction. Japan and South Korea increased coal-fired power generation from April through early May as LNG supplies were disrupted and prices surged in global markets, according to Kyodo data reported by multiple outlets. Gas-fired electricity generation fell as utilities switched to cheaper, dirtier fuel.^5,6 The scale of the coal rebound is significant. Vietnam's coal-fired electricity generation climbed 12.3% in April to a record 17,864 gigawatt-hours, according to government figures. Japan's increased coal generation displaced roughly four LNG cargoes in April alone, about half the annual reduction in imports the government had expected from green energy targets, according to Fei Xu, senior gas analyst at ICIS.⁶ For South Korea, the contradiction is stark. The country sources 70% of its oil and 20% of its natural gas from the Middle East, according to the Economist. The disruption to those supplies has forced a return to coal at exactly the moment Seoul is funding methane reduction overseas. South Korean Finance Minister Koo Yun-cheol has called for strengthening regional cooperation to face growing economic uncertainty driven by the conflict.^2,4 Indonesia's own energy trajectory makes the methane deal more complex. The country is in the early stages of an investment boom, with green industrial parks and metals processing expanding rapidly. In West Kalimantan, on the island of Borneo, Adaro Energy Indonesia is building a hydropower plant to produce "green" aluminium smelted using low-carbon energy. The investment extends beyond metals processing to manufacturing.³ But Indonesia also sits at the centre of Southeast Asia's surging power demand. Data centres, electric vehicles, and industrial expansion across the region are expected to add more than 100 terawatt-hours of demand over the next three to four years, according to the 2026 Southeast Asia Green Economy Report published by Bain & Company and Standard Chartered. Meeting that surge will require investments exceeding $200 billion, with more than half expected to flow into data centres.¹ The investment pipeline is fragile. Only around 60% of the $540 billion in announced green investments across power and EV supply chains is considered likely to proceed under current conditions, the report found. Renewable energy projects in Indonesia, Vietnam, and Thailand have faced setbacks, with 50% to 60% cancelled over the past five years due to regulatory uncertainty, permitting issues, and limited grid capacity.¹ That grid gap is the bottleneck. Annual grid investment shortfalls are estimated at $18 billion by 2035, according to the Bain report. Without transmission infrastructure to connect renewable generation to demand centres, countries like Indonesia will default to fossil fuels regardless of how many methane programmes they sign up to.¹ Southeast Asia's green economy is currently valued at $290 billion and is projected to expand to $430 billion by 2030, reflecting growing investment in clean energy across the region. But the projection assumes policy stability and infrastructure delivery that recent events have called into question.¹ South Korea's own industrial ambitions add context. President Lee Jae Myung envisions spending $530 billion over two decades on the chip industry, with Samsung Electronics and SK Hynix pledging a combined $700 billion to the project by 2047. That level of industrial investment requires reliable, affordable energy. The current crisis, with Middle Eastern supplies disrupted, makes energy security a prerequisite for every other economic goal.² The $20 million methane initiative is small relative to the forces pushing against it. A single month of increased coal burn across Asia likely produces more emissions than the programme could abate in a year. But the deal signals that both Jakarta and Seoul want to maintain climate credentials even as short-term energy decisions move in the opposite direction. The question for gas markets is whether the coal-to-gas switch reverses when LNG prices normalise. Analysts said rising prices and supply concerns have pushed Asian utilities to rely more heavily on coal, particularly to meet electricity demand during nuclear plant maintenance ahead of summer. If the Iran disruption eases, gas demand should recover. If it persists, the coal rebound could harden into a longer-term shift that makes methane mitigation programmes look like a sideshow.^5,6
