The Environmental and Social Impact Assessment Team conducts research on the evaluation of innovative technologies essential for achieving a zero-emission society. By leveraging specialized expertise in technology and a comprehensive perspective, we assess the environmental and socio-economic impacts of technology adoption. Additionally, we analyze the role of these technologies within the energy system using mathematical models and develop scenarios to achieve carbon neutrality.

Specifically, we focus on the following three themes:

Long-term energy scenario analysis using mathematical models

Using mathematical models such as “AIST-MARKAL” and “AIST-TIMES,” we simulate future energy supply and demand to analyze scenarios for the introduction of low-carbon technologies toward carbon neutrality. The simulation results serve as fundamental information for guiding technology development and policy design essential for achieving carbon neutrality.

Assessing technologies based on systems/life cycle thinking

We evaluate the impacts of emerging technologies—including environmental, economic, social, and supply stability aspects—based on specialized expertise in technology and a comprehensive perspective. By taking a holistic view of the entire energy system and supply chain, we identify the key technological elements and institutional frameworks necessary for integrating innovative technologies into society.

Sustainable biomass utilization through the Water-Energy-Food (WEF) nexus approach

We evaluate the sustainability of biomass utilization through the Water–Energy–Food (WEF) nexus approach, which assesses resource efficiency, greenhouse gas emissions, and environmental trade-offs. The nexus index serves as a valuable tool for projecting the long-term environmental and socio-economic benefits of biomass utilization to ensure a more sustainable and resilient future, particularly in the Asian countries.
