ST Advances Towards Carbon Neutrality Goal

STMicroelectronics’ 2025 sustainability results show progress towards its 2027 carbon neutrality goal and broader ESG targets. 

Jean Louis Champseix, Group Vice President Corporate Sustainability at STMicroelectronics, shares, “Our 2025 sustainability results, marking the second year of reporting under the Corporate Sustainability Reporting Directive (CSRD). Using 2024 as a baseline, the 2025 Annual Report provides an updated view of our trajectory towards carbon neutrality by 2027 and our broader environmental and social ambitions.”

ST has sourced 86% of its electricity from renewables, supported by PPAs, energy certificates, onsite generation, and a major district cooling project in Singapore. 

The company prepares to offset residual emissions from 2026 onwards and strengthening cross functional governance, supplier engagement, and alliances such as RBA and AWS to drive decarbonization and responsible business practices.

Key Results

• Climate adverse process gases abated: 83% (up from 76% in 2024), keeping ST on track to reach 90% abatement by 2030.
• Waste diverted from disposal: 97%, as in 2024, and above the goal to recycle, recover, and prepare for reuse at least 95% of waste each year.
• Water recycled or reused: 51%, slightly down from 53% in 2024. ST has projects underway to reach 60% by 2035.
• Safety total recordable case rate: 0.47 (using CSRD methodology), compared to 0.65 in 2024 and better than the goal of <0.75.

• Labor and human rights: 10 of 11 manufacturing sites with Responsible Business Alliance (RBA) platinum recognition as in 2024.
• Women in management: 22%, up from 21% in 2024, progressing towards 25% by 2035.

ST remains on track to achieve carbon neutrality by the end of 2027 for its direct and indirect emissions (Scopes 1 and 2) and product transportation, business travel, and employee commuting emissions (Scope 3).

As part of ST’s 2027 carbon neutrality plan, ST is preparing to address residual emissions. 

In 2025, a roadmap for offsetting residual emissions was defined, identifying carbon credit suppliers that support credible projects and are aligned with recognized quality standards. 

This work will allow ST to start offsetting residual emissions from 2026, alongside its continued focus on reducing emissions across its own operations and upstream value chain.
