United Microelectronics (UMC) Carbon Emissions and Climate Commitments

United Microelectronics (UMC), an electrical machinery and apparatus company headquartered in TW, has reported significant greenhouse gas (GHG) emissions across its operations.

Recent Emissions Data:

• 2024: UMC reported total GHG emissions of approximately 3.62 billion kg CO2e. This breaks down into approximately 463.7 million kg CO2e for Scope 1 emissions, approximately 1.52 billion kg CO2e for Scope 2, and approximately 1.71 billion kg CO2e for Scope 3.
• 2023: Total emissions were approximately 3.95 billion kg CO2e, comprising about 509.6 million kg CO2e (Scope 1), 1.64 billion kg CO2e (Scope 2), and 1.89 billion kg CO2e (Scope 3).
• 2022: The company's total emissions stood at approximately 4.59 billion kg CO2e, with Scope 1 emissions at about 866.0 million kg CO2e, Scope 2 at approximately 1.76 billion kg CO2e, and Scope 3 at approximately 2.06 billion kg CO2e.
• 2021: UMC reported total emissions of approximately 5.61 billion kg CO2e, including about 989.4 million kg CO2e (Scope 1), 1.78 billion kg CO2e (Scope 2), and 2.83 billion kg CO2e (Scope 3).

Climate Commitments and Reduction Targets:

UMC has established ambitious climate targets aligned with global sustainability goals.

• Near-Term Targets:

  • UMC has committed to a 42% reduction in Scope 1 and Scope 2 GHG emissions by 2030, using 2020 as the base year.
  • A 25% reduction in carbon emissions within its value chain (Scope 3) is also targeted for the same timeframe.
  • The company has Science Based Targets initiative (SBTi) approved targets, including a commitment to reduce absolute Scope 1 and 2 GHG emissions by 25% by 2030 from a 2020 base year. Additionally, an absolute reduction of 12.3% in Scope 3 GHG emissions is targeted within the same period.

• Long-Term Targets:

  • UMC aims to achieve net-zero GHG emissions across its value chain by 2050.
  • This includes a long-term commitment to reduce emissions by at least 90% and neutralise or offset any remaining unavoidable carbon emissions to meet the net-zero target.
  • SBTi also shows commitments for long-term reductions, including a 95% reduction in Scope 1 and Scope 2 emissions by 2050 from a 2020 base year, and a 90% reduction in Scope 3 emissions by 2050.

These targets demonstrate UMC's dedication to mitigating its climate impact and contributing to a sustainable future within the electrical machinery and apparatus sector.
