Taiwan Semiconductor Manufacturing's reported carbon emissions

## Taiwan Semiconductor Manufacturing (TSMC) Carbon Emissions and Climate Commitments Taiwan Semiconductor Manufacturing (TSMC), headquartered in TW and operating in the Electrical machinery and apparatus n.e.c. (31) industry, has reported significant carbon emissions across its operations. In 2024, the company's total reported emissions, encompassing Scope 1, 2, and 3, were approximately 20.6 billion kg CO2e. This breaks down into approximately 1.8 billion kg CO2e for Scope 1 emissions, and approximately 10.9 billion kg CO2e for Scope 2 emissions (market-based). Scope 3 emissions for 2024 amounted to roughly 8.2 billion kg CO2e, with purchased goods and services (approximately 5.7 billion kg CO2e) and fuel and energy-related activities (approximately 2.5 billion kg CO2e) being the largest contributors within this scope. In 2023, TSMC reported total emissions of approximately 19.1 billion kg CO2e. Scope 1 emissions were around 1.6 billion kg CO2e, while Scope 2 emissions (market-based) stood at approximately 10.2 billion kg CO2e. Scope 3 emissions for that year totalled approximately 7.6 billion kg CO2e, with purchased goods and services accounting for the largest portion at approximately 4.9 billion kg CO2e. TSMC has established ambitious climate commitments. The company aims to achieve net-zero emissions by 2050 for both Scope 1 and Scope 2 emissions. Furthermore, TSMC overseas sites have achieved net-zero emissions in Scope 1 and 2 for the period of 2023-2025. The company is also actively working on reducing its environmental impact through various initiatives, including optimisation of manufacturing process gases, minimisation of global warming potential, and the comprehensive adoption of best available technology. This led to a significant reduction in direct emissions of 320 metric tons CO2e and a 65% reduction in fluorinated greenhouse gas emissions per unit of production, achieving a 2020 reduction goal ahead of schedule. TSMC also plans to increase renewable energy purchasing for new wafer fabs, aiming for 20% of energy consumption for new fabs after 3nm.
