UMC Achieves 1.5°C Net-Zero Targets Validation by Science Based Targets Initiative

United Microelectronics Corporation (UMC) has had its 1.5°C Net-Zero targets validated by the Science Based Targets initiative (SBTi). UMC is the first semiconductor foundry worldwide to receive approval for targets under this standard. The company has set targets to achieve net-zero GHG emissions by 2050, reduce Scope 1 and 2 emissions by 95% and Scope 3 emissions by 90% by 2050. UMC has outlined specific reduction strategies for each emissions category, including a Supply Chain Greenhouse Gas Inventory Initiative launched in 2022.

Title: UMC's Net-Zero Targets Validated by SBTi: A Milestone in Semiconductor Sustainability

United Microelectronics Corporation (UMC), a leading global semiconductor foundry, has achieved a significant milestone in its sustainability efforts. The Science Based Targets initiative (SBTi) has officially validated UMC's near-term, long-term, and net-zero targets, aligning with the 1.5°C pathway. This recognition positions UMC as the first semiconductor foundry worldwide to receive approval for targets under this stringent standard.

UMC's commitment to climate action spans over two decades, with a solid foundation laid in 2021 when the company joined the RE100 initiative and pledged to reach net-zero emissions by 2050. The company has adopted a multifaceted approach to emissions reduction, including expanding the use of renewable energy, improving energy efficiency, and implementing low-carbon manufacturing processes [1].

The validated targets set by UMC are as follows:
- Net-Zero Target: Achieve net-zero GHG emissions by 2050.
- Long-Term Targets:
- Reduce Scope 1 and 2 emissions by 95% by 2050.
- Reduce Scope 3 emissions by 90% by 2050.
- Near-Term Targets:
- Reduce Scope 1 and 2 emissions by 42% by 2030.
- Reduce Scope 3 emissions by 25% by 2030.

To support these ambitious goals, UMC has outlined specific reduction strategies for each emissions category. The company has launched the Supply Chain Greenhouse Gas (GHG) Inventory Initiative in 2022, providing tools and resources for measuring and managing emissions. Over 400 suppliers have participated in this initiative, with high-emission suppliers receiving carbon hotspot analysis, energy diagnostics, and tailored decarbonization recommendations [1].

UMC's strategic focus on 22/28nm mature-node technology has not only positioned the company to capture a significant share of the foundry market but also to mitigate macroeconomic headwinds. The company's 22nm embedded high-voltage (eHV) platform has secured over 90% of the small-panel AMOLED market since 2020, reducing power consumption by 30% and shrinking die area by 10% compared to 28nm alternatives [2].

The company's geographic diversification strategy is another key factor in its resilience. The expansion of its Singapore Fab 12i Phase 3 in 2026 will add 22nm capacity and provide a politically stable manufacturing hub. This diversification helps UMC balance its 66% revenue concentration in Asia Pacific with 22% in North America and 7% in Europe, reducing exposure to localized disruptions [2].

Investors and financial professionals can look at UMC's forward P/E of 12.5x and a dividend yield of 3.2% as indicators of both growth and income potential in a sector prone to volatility. The company's strategic agility and focus on mature-node markets offer a rare combination of stability and growth in the semiconductor industry.
