Response to Climate Change

Concept of Climate Change "Mitigation"

Concept on How to Mitigate the Impact of Climate Change

Looking at the composition of greenhouse gas (GHG) emissions associated with our group’s operations, emissions arising from the consumption of our products (Scope 3) far exceed emissions from our refineries, complexes, and plants (Scope 1) and emissions mainly attributable to purchased energy (Scope 2). Scope 3 emissions constitute the overwhelming majority of our emissions (see the graph below). This is why we prioritize reducing GHG emissions across value chains. Accordingly, our reduction efforts not only aim to curb Scope 1 and 2 emissions, but also target Scope 3 emissions. In doing so, we are placing the utmost priority on reducing CO2 emissions, which account for more than 90% of Japan’s GHG emissions.

Value chains related to Idemitsu Group operations are diverse. Therefore, we are better placed to help reduce CO2 emissions from value chains in a range of areas. Looking ahead, we will strengthen our efforts in these areas and contribute to a reduction in CO2 emissions.

Our Group’s CO2 Emissions by Scope (FY2019)
  • *1. Scope of calculation: Idemitsu Kosan and consolidated subsidiaries
  • *2. Data regarding GHG emissions (CO2 equivalent) is featured on “ESG Data” .

In conjunction with business integration in 2019, we found differences of calculation methods used by the two pre-merger companies for measuring CO2 emissions The differences are outside of the scope of the relevant domestic regulations requiring disclosure. In response, we partially revised and otherwise upgraded our calculation methods with reference to the globally accepted disclosure standards.

Business value chains and efforts to reduce CO2 emissions
Reducing CO2 emissions in value chains
  1. Example1Reducing fuel consumption by improving the operational efficiency of crude oil carriers
  2. Example2Reducing fuel consumption by promoting energy-saving at refineries
  3. Example3Reducing coal consumption by introducing a high-efficiency combustion system for coal-fired boilers
  4. Example4Reducing dependence on fossil fuel power generation by expanding renewable energy power generation
  5. Example5Expanding renewable energy power generation by manufacturing and supplying solar panels
