Japan is focusing on promoting its energy transition approach, emphasizing carbon abatement technologies, to the coal-reliant Asia-Pacific region. The country has accelerated the development of carbon abatement technologies to maintain fossil fuels in its energy mix, ensuring energy security and economic growth. Japan, along with its G7 counterparts, has committed to phasing out 'unabated' coal-fired plants by 2035, aligning with the goal of limiting a temperature rise to 1.5°C. To support this endeavor, Japan's trade and industry ministry has requested significant funding to advance carbon capture and storage (CCS) projects, including exploring CO2 storage sites. Japan aims to achieve net zero emissions by 2050, with a focus on clean fuels like hydrogen and ammonia. The country is also keen on extending its vision for diverse pathways to decarbonization, including thermal power with abatement, to coal-reliant southeast Asia. Through the Asia Zero Emission Community (Azec), Japan is leading efforts to promote decarbonization in the region by offering financial support and technological know-how. Japan's commitment to reducing its GHG emissions and providing financial assistance underscores its leadership in advocating for a cleaner energy future.
