In 2024, Sumitomo Metal Mining reported total carbon emissions of approximately 1,724,000,000 kg CO2e for Scope 1, 632,000,000 kg CO2e for Scope 2, and a significant 4,950,000,000 kg CO2e for Scope 3 emissions. The combined total for Scope 1 and 2 emissions reached about 2,356,000,000 kg CO2e. This data reflects a comprehensive approach to emissions reporting, covering all relevant scopes. In 2023, the company recorded emissions of about 1,830,000,000 kg CO2e for Scope 1 and 726,000,000 kg CO2e for Scope 2, resulting in a total of approximately 2,556,000,000 kg CO2e for these scopes. Notably, there is no disclosed data for Scope 3 emissions for that year. For the year 2022, emissions in Japan were reported at approximately 484,000,000 kg CO2e for Scope 1 and 854,000,000 kg CO2e for Scope 2, totalling around 1,339,000,000 kg CO2e for Scope 1 and 2 combined. Global emissions for the same year included about 1,965,000,000 kg CO2e for Scope 1 and 858,000,000 kg CO2e for Scope 2, leading to a total of approximately 2,823,000,000 kg CO2e. Despite the substantial emissions figures, Sumitomo Metal Mining has not publicly committed to specific reduction targets or initiatives, as indicated by the absence of documented reduction targets or SBTi commitments. The company’s climate strategy appears to be in the early stages, with no significant pledges or initiatives reported at this time. Overall, while Sumitomo Metal Mining has demonstrated transparency in its emissions reporting, further commitments and reduction strategies will be essential for aligning with global climate goals.
