Environmental Reporting Our Company regularly reports its efforts and data pertaining to environmental sustainability to the Carbon Disclosure Project (CDP), which is comprised of investors who represent a total of USD 100 trillion in assets globally. 2023 calendar year CDP reporting was completed on 09 October 2024. In 2024, we managed to maintain our climate change score at last year’s “B-Governance” level by quickly and effectively adapting to the most comprehensive changes in the history of the CDP platform (integration with IFRS ISSB, addition of water, biodiversity and plastic pollution sections). We also achieved a “B-” score in our Water Security reporting for the first time. On this platform, which we have been involved in since 2012, we continue to improve our sustainability performance in line with our environmental policy commitments. We also include our information and data regarding environmental management in our Annual Reports, which we are sharing with our investors and the public since 2001.
