Management Approach

Why the topic is material

As an energy business operator, it is vital for the Daigas Group to promote more efficient use of energy resources and reduction of curtail greenhouse gas emissions through the entire range of our business activities and value chain, from the procurement of natural gas and other raw materials and fuels to the production and supply of city gas and generation of power, extending to the supply to customers, where consumption takes place.

Amount of reduction in CO2 emissions


We work hard to reduce the greenhouse gas emissions of the Group as a whole, based on the Daigas Group Environmental Policy. In order to manage the efforts, we have set long-term CO2 emissions reduction targets for FY2031, as well as medium-term environmental action targets, of which progress is monitored to assure its achievement. Also, we calculate GHG emissions annually in group activities across the value chain, and use that information to promote efforts to reduce those emissions.

The Daigas Group uses indicators and targets to help reduce GHG emissions in each business domain. The performances as well as actions for such indicators and targets are supervised by the Environment Subcommittee, ESG Committee, and ESG Council (Executive Board). The PDCA (plan-do-check-act) cycle is used to manage such actions.

PDCA (plan-do-check-act) cycle


Several new initiatives have been taken from FY2018 to FY2021. The initiatives in Japan include: cryogenic power generation at our LNG terminals, the introduction of renewable energy sources in Japan and high-efficiency thermal power generation in both Japan and abroad, the introduction of fuel cells and gas-powered air conditioning and high-efficiency hot-water heaters at customer sites, and conversion to the use of natural gas as a fuel in both Japan and abroad. These efforts have resulted in a total reduction in CO2 emissions of approximately 5.6 million tons.
