Climate Goals & Targets

Long-term Goals:
  • Achieve an absolute reduction of 90% Scope 1+2+3 emissions in 2050 compared with the base year of 2021.
  • Achieve net zero emissions by 2050.
  • Use 100% renewable energy by 2050.

  • Reduce waste solvent volume (kg/6"e wafer) by 24% from 2018.
  • Renewable energy use reaches 30%.
Short-term Goals:
  • Reduce electricity consumption (kWh/6"e wafer) by 12% from 2018.
  • Reduce PFCs emissions (ton CO2e /6"e wafer) by 5% from 2023.
  • Reduce water withdrawal (m3/6"e wafer) by 5% from 2023.
  • Reduce waste solvent volume (kg/6"e wafer) by 1% from 2023.

Environmental Challenges

  • Relatively low capacity utilization in 2023 due to customer inventory adjustments, resulting in higher electricity consumption and water withdrawal per unit wafer than the annual management goal.
  • Extreme weather events (extreme precipitation and droughts, changes in rainfall patterns and distribution, average rainfall changes).
  • Transition risks (renewable energy regulations, increase in the cost of greenhouse gas emissions, investment in new technology, uncertainty in market signals, changing customer behavior, impact on company reputation).
Mitigation Strategies
  • Improved fabs' ability to adapt to water shortages, improved water use efficiency, backup suppliers for main upstream and downstream materials and safe supply storage levels.
  • Assess flooding risks for the fabs and make adjustments, strengthen flood protection and response abilities.
  • Install renewable energy power generation equipment in fabs, look for purchasing renewable energy certificates, established the ISO 50001 Energy Management System.
  • Set up a Carbon and Energy Reduction Task Force, established the ISO 50001 Energy Management System, implemented government's greenhouse gas offset project and equipment replacement.
  • Invest in the production of low-carbon products, continue to develop new processes, and use equipment that consumes less energy for production, publish sustainability reports, actively respond to domestic and foreign sustainability assessments and proactively disclose relevant information, implement life cycle assessments, carbon footprint, and water footprint inventories.

Supply Chain Management

Supplier Audits: 24 on-site inspections on waste clearance and disposal organizations in 2023.

Responsible Procurement
