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. 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 the value chain in a range of areas. Looking ahead, we will strengthen our efforts in these areas and
contribute to a reduction in CO₂ emissions.

Reducing CO₂ emissions throughout the value chain

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
