Climate Change (FY2022)

Materiality Indicators

Management Approach

Why the topic is material

Tackling climate change is seen as one of the Sustainable Development Goals (SDGs) adopted by the United Nations. For the Daigas Group, climate change represents an important management challenge, and initiatives to reduce CO2 emissions are a crucial mission.


Within and beyond the Group

Management systems and performance

Indicator (GRI Standards: 302-1, 305-5)
  • ・Achievement of carbon neutrality (Group’s CO2 emissions)
  • ・Provision of clean energy and expansion of renewable energy value chain (Percentage of renewable energy power sources, contribution to the spread of renewable energy)
  • ・Advanced use of natural gas and spread of ecological products (Contribution to reduction in CO2 emissions)

The Daigas Group is committed to achieve a low-carbon/carbon-neutral society under the Daigas Group Carbon Neutral Vision, which was formulated and announced in January 2021 and expresses the Group’s determination to take on the challenge of achieving carbon neutrality by 2050.

(International and domestic standards)

  • ISO14001
  • GHG Protocol
  • ・Act on the Rational Use of Energy
  • ・Act on Promotion of Global Warming Countermeasures

(In-house policy and standards)

  • ・Daigas Group Code of Business Conduct
  • ・Daigas Group Environmental Policy
  • ・Rules for Environment Management Systems

The Daigas Group uses indicators and targets to help reduce GHG emissions and expand the use of renewable energy 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 (Management Meeting). The PDCA (plan-do-check-act) cycle is used to manage such actions.


We devote positive efforts to reduce CO2 emissions from liquefied natural gas (LNG) transportation, city gas production, and power generation. We also implement various energy-saving measures at offices, scale them up Group-wide, and verify their effects by continuously checking energy usage data. The CO2 emissions of the Daigas Group in FY2022 were approximately 26.79 million tons.

We promote the spread of renewable energy sources, such as wind, solar, and biomass. In FY2022, the percentage of renewables in our power portfolio was 8.1%, and renewables development contribution was approximately 1.398 GW.

We took several initiatives, including the use of cryogenic power generation at our LNG terminals, the introduction of renewable energy sources in Japan and high-efficiency thermal power generation in Japan and abroad, the introduction of fuel cells, 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 Japan and abroad. These efforts resulted in approximately 3.36 million tons in CO2 emissions reduction contribution in FY2022.

Specific Actions Taken Regarding Materiality

In order to realize the Daigas Group Carbon Neutral Vision, we aim to become carbon neutral in our group business by 2050 through innovation for decarbonization technologies. We work on decarbonization technologies for gaseous energy, such as methanation. In addition, believing that it is important to ensure CO2 emissions reduction until the establishment of decarbonization technologies, we have set targets for 2030 as the milestones for renewables in our power portfolio, renewables development contribution, and CO2 emissions reduction contribution as our contribution to achieving a low carbon / carbon neutral society.
