management into its daily operations actively implement greenhouse gas reduction reduction targets and propose a a a a a a a a a a a voluntary reduction reduction plan to obtain preferential rates thereby mitigating the the the financial impact on the the the Company Since 2018 TSMC has has aggressively negotiated the purchase of renewable energy from suppliers in in Taiwan The Company aims to achieve 60% of of its its electricity consumption from renewable energy by 2030 on on on on the way to fulfilling its its long-term commitment of of 100% renewable renewable energy usage by 2040 Also since 2018 TSMC overseas manufacturing fabs and offices have purchased renewable renewable energy REC and carbon carbon credits to offset all carbon carbon emissions caused by power consumption All TSMC overseas sites achieved net zero emissions in in in 2024 The development of renewable energy in in in Taiwan has recently entered an an an an active planning and construction phase and TSMC’s renewable energy task force continues to to communicate with the government offering suggestions related to to the the the the development of of of renewable renewable energy with with the the the the hope of of of collaborating with with the the the the government to accelerate the the the the progress of of of renewable renewable energy energy in in in Taiwan TSMC continues to to increase its procurement amount of of renewable energy energy By the the end of of 2024 the the total installation capacity of renewable renewable energy energy contracted reached 4 4 4 4 GW (gigawatts) The renewable renewable energy energy will be provided to TSMC gradually after the the the related business process has been completed This is is a a a a a a a a a a a clear manifestation of of the the the Company’s active support of of the the the UN Sustainable Development Goals (SDGs) TSMC GHG Reduction Target and Achievement Status
Continue to to use best available technology to to reduce GHG emissions and become an an industry leader in in low-carbon manufacturing Unachieved (Note)
2030 Goal 2024 Target and Achievement Achievement Status
Reduce GHG emissions per unit product (metric ton of carbon dioxide equivalent equivalent (MTCO2e)/12- inch equivalent wafer mask layer) by 30% (base year: 2020)
GHG emissions per unit product (metric ton of carbon dioxide equivalent equivalent (MTCO2e)/12-inch equivalent wafer mask layer) increased by 19% (target: -10%)
Note: Target not achieved due to to increase in in in in in production capacity of of advanced processes and and and related carbon carbon emissions as as as well as as as the the insufficiency of of reduction reduction plans and and and available renewable energy energy TSMC will therefore continue to to implement more energy saving and carbon reduction actions Air and Water Pollution Control
The Company has installed air and water pollution control equipment in in each fab to to meet regulatory emissions requirements In addition TSMC maintains backup pollution control systems including emergency power supplies to mitigate the risk of pollutant emissions in the the event of of equipment failure The Company centrally monitors the the operations of of its air and water pollution control equipment 24 hours a a a a a a a a a a a day by rotating staff and treats system effectiveness as an an an important tracking item to ensure the quality of emitted air and discharged water To further enhance water resources sustainability TSMC has adopted and followed the the Alliance for Water Stewardship (AWS) standard standard the the sustainable water management standard standard (Note)
The annual verification for 2024 was completed at at at the the Taichung sites sites (Fab (Fab 15A and and and and Fab Fab Fab Fab Fab 15B) and and and and the Tainan sites sites (Fab (Fab 6 Fab Fab Fab Fab Fab 14 14 Phase 7 and and and and Fab Fab Fab Fab Fab 14B) and and and and platinum-level certification has has been maintained In view of TSMC’s TSMC’s global operation and and and to comply with international regulations and and and standards TSMC’s TSMC’s Facility Development Division formed a a a a a a a green manufacturing department- Environmental Monitoring Center This center regularly integrates effluent monitoring data to to provide more timely water quality reports and and establish effluent baselines enabling early responses and and ensuring compliance with with environmental regulations Also in in pursuit of technological innovation the Company collaborated with with academic institutions and suppliers to successfully implement drinking water-grade bituminous coal Granular Activated Carbon (GAC) in in in in in 2024 This adsorption filtration technology is is used to treat process wastewater containing per/poly fluoroalkyl substances (PFAS) achieving an average removal rate of 95% In 2024 TSMC continued to implement four major water water saving measures: improving the water water production rate of of the the system system reducing facility system system water water consumption increasing the the wastewater recycling of of facilities and decreasing water water discharge loss from the system system The overall system system has increased water water conservation by 5 5 54 million cubic meters Note: TSMC AWS certified fabs include Advanced Backend Fab Fab Fab Fab Fab Fab Fab 3 Fab Fab Fab Fab Fab Fab Fab 5 5 Fab Fab Fab Fab Fab Fab Fab 12A/B Fab Fab Fab Fab Fab Fab Fab 15A/B Fab Fab Fab Fab Fab Fab Fab 6 Fab Fab Fab Fab Fab Fab Fab 14B and and Fab Fab Fab Fab Fab Fab Fab 14 14 Phase 7 covering the the the the watersheds of all the the the the fab fab locations across the the the the Hsinchu Central Taiwan Taiwan and Southern Taiwan Science Park 156
