International Network of AIM (Asia-Pacific Integrated Model)

The 28th AIM International Workshop in 2022 (Online)

Website of AIM• Asian countries will update their mitigation target and roadmap to achieve the 2/1.5 degree target reflecting their issues
to be solved and the resources to be endowed.
• Model can be a collaboration tool between science and decision making process. From the long-term viewpoint, eachcountry will need the capacities to develop model and scenarios by itself.
• AIM (Asia-Pacific Integrated Model) has supported
Asian countries to develop the integrated assessment
model and their long-term low carbon scenarios.

GHG emissions in Japan• We analyzed "technology" scenario in which net-zero emissions will beachieved through the diffusion of decarbonization technologies such asenergy conservation, renewable energy, and electrification, and a"technology + social transformation" scenario in which the diffusion ofdecarbonization technologies is combined with progress of digitalization,circular economy, etc.
• Fossil fuels currently account for more than 80% of the total primary energy
supply, but by 2050, renewable energy will account for about 70%, andenergy self-sufficiency will have improved significantly from 15% (2018) to70% (2050).
• A large proportion of energy-related CO2 emissions in 2050 will come fromsynthetic fuels, and since a certain amount of emissions will be inevitableeven if decarbonization measures are promoted in 2050, negative emission
technologies will be necessary to reduce GHG emissions to virtually zero.
• To achieve a decarbonized society, additional investment of 9-11 trillion yen
per year will be needed for insulation of houses and buildings, renewableenergy, etc. Net energy imports will drop from about 16 trillion yen (2018) to
4-5 trillion yen in 2050.
