This paper, authored by an international research team led by Associate Professor Masayuki Kondo, Director of the Sustainability Division at the Seto Inland Sea Carbon Neutral Research Center of Hiroshima University, with the participation of Dr. Prabir Patra and Ms. Kirari Hirabayashi, presents a comprehensive and systematic assessment of the greenhouse gas budget in Southeast Asia.
Through this international collaborative research led by Hiroshima University, the study reveals that Southeast Asia has become one of the major sources of greenhouse gases that accelerate global warming. It demonstrates that this situation is driven by a combination of factors, including deforestation, degradation of peatlands, frequent fires, and the rapid expansion of fossil fuel use.
The findings were published on September 24, 2025, in the academic journal Global Biogeochemical Cycles, highlighting the magnitude of the challenges that Southeast Asian countries face in achieving climate neutrality, and strongly emphasizing the urgent need to reinforce cooperation at both regional and international levels.
