Sustainability Medium-term Plan for Planet

Reduction of Environmental Load/Setting New Goals for GHG Emission Reduction

The results for Scope 1,2 emissions in 2024 were 2,868 thousand tons- CO₂e. Although Scope 1, 2 GHG emissions in 2024 were 132 thousand tons- CO₂e higher than in 2023 due to the full-scale operation of new Thai plant for isoprene products, along with the start-up of new activated carbon facilities in the United States, we remained below our emission targets (3,020 thousand tons- CO₂e in 2021 benchmark level) owing to measures to save energy and boost production efficiency. As in the previous year, we took measures to promote the greening of electricity, including the purchase at overseas Group companies of Unbundled Energy Attribute Certificates (renewable energy certificates).
　Meanwhile, we are exploring Carbon dioxide Capture, Utilization and Storage (CCUS*) to deal with the CO₂ released as a byproduct in the manufacture of coal-based activated carbon in the United States. This is being developed as a corporate project based on a cross-organizational project team. In 2024, we calculated the required capacity for CO₂ capture equipment to cope with the emissions of the various plants of Calgon Carbon Corporation and researched the test phase prior to facility installation. We also studied relevant options from a list for CO₂ storage projects in the area around the Pearl River Plant, including the possibility of gaining eligibility under the U.S. Inflation Reduction Act.

* Carbon dioxide Capture, Utilization, and Storage: An initiative to utilize or store CO₂ separated from exhaust gas from industrial facilities.

In Japan, we reported our GHG emissions results for the period from April 2023 to March 2024 to the GX League*, which we joined in 2023. These results were restructured and verified by a third party. By participating in the GX League, we aim to achieve our GHG emission reduction goals while considering external collaboration.

* The GX League is a public-private partnership framework in which a group of companies challenge the transition to carbon neutrality.
