We are committed to energy conservation, carbon reduction, and hazardous substance reduction to minimize environmental impact. All manufacturing sites are designed and operated in compliance with local environmental regulations and strive to exceed regulatory standards to create a greener environment. To reinforce our environmental commitment, MPI implemented the ISO 14001 Environmental Management System in 2016 and successfully obtained certification. We have continued to pass verification audits, most recently in 2025, with the current certification valid until September 19, 2028. Additionally, to enhance energy efficiency, we already implemented the ISO 50001 Energy Management System (EnMS) in 2016 and have since maintained its operation.
Since 2022, MPI has promoted organization-wide greenhouse gas (GHG) inventories and adopted 2022 as the baseline year to establish a comprehensive GHG management system. This initiative ensures the accuracy and transparency of emissions data across all facilities. MPI conducts annual third-party GHG verifications and, in accordance with regulatory requirements, is gradually expanding these audits to all subsidiaries to strengthen the Company’s overall carbon management framework.
In 2024, MPI established its carbon reduction targets, committing to reduce Scope 1 and Scope 2 greenhouse gas emissions by 10% to 20% compared to the 2022 baseline year by 2030, and to achieve carbon neutrality by 2040. Progress toward these goals is monitored quarterly by the Board of Directors through regular reviews of GHG inventories and reduction measures to ensure effective implementation. In 2024, MPI completed four Board of Directors reports covering GHG inventory results, verification progress, and implementation outcomes. We remain committed to strengthening carbon reduction strategies, advancing its low-carbon transition, and driving sustainable business development.
