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.
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.
