The only national target in Japan in relation to CO2 reduction was adopted on 22 October 2021, when Japan’s Cabinet approved the “Plan for Global Warming Countermeasures“. There are currently no specific targets decided solely in relation to CO2 reduction and/or energy-use reduction from buildings.

This plan is the first revision in five years of the plan adopted in 2016. In April 2021, Japan announced its goal to reduce greenhouse gas emissions by 46% in FY2030 compared to FY13.

The new plan is designed to achieve the above goal, calling for the expansion of renewable energy, the expansion of mandatory compliance with energy conservation standards for homes and buildings, and the creation of decarbonized major regions.
