Energy & Climate Change

エネルギー & 気候変動


ST has been actively working on reducing its environmental footprint through dedicated programs for many years. In 2019 we had already achieved the goal set for 2025 regarding greenhouse gas emission reduction, with a 21% reduction per unit of production compared with 2016. 
ST is stepping up its ambition and plans for the sustainability of its operations. 
We will become carbon neutral by 2027, for the 40th anniversary of ST’s creation.
ST’s comprehensive roadmap to carbon neutrality includes two specific targets:
- compliance with the 1.5°C scenario defined at the Paris COP21 by 2025, which implies a 50% reduction of direct and indirect emissions compared to 2018, and
- the sourcing of 100% renewable energy by 2027.

Carbon neutral identifier

How we will reach our 2027 target 

  • Reduce as much as possible our direct emissions by decreasing emissions generated by ST sites with measures such as PFC* (Perfluorinated Compounds) abatement systems (Scope 1). 
  • Invest in energy saving programs. Reduce electricity consumption by identifying and deploying ways to reduce our indirect carbon emissions related to our electricity consumption on all ST sites (Scope 2).
  • Innovate for our renewable energy supply to reach 100% for all ST by 2027 through power purchase agreements, on-site electricity generation, and green certificates.
  • Minimize our indirect emissions from transportation (employees’ commuting, product transportation, business travel) by offsetting new emissions linked to company growth (Scope 3).
  • Compensate remaining emissions through reforestation and innovative carbon sequestration programs.



Being 1.5°C scenario compliant by 2025

We joined the world-renowned Science Based Target Initiative (STBi) which has validated ST’s targets to be compliant with the 1.5°C maximum scenario as per the COP21 Paris agreement. This means reducing direct and indirect absolute carbon emissions by 50% compared to 2018.




Partnership and open innovation

We are collaborating with external partners to develop innovative green solutions. We are also encouraging all stakeholders to join us in this transformation, and we are promoting the approach accross ecosystems.

  Contributing to the Sustainable Development Goals

Our commitments and programs related to Energy and Climate Change contribute to:

  • SDG target 7.3 - By 2030, double the global rate of improvement in energy efficiency.
  • SDG target 8.4 - Improve progressively, through 2030, global resource efficiency in consumption and production.
  • SDG target 13.1 - Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries


More information on our programs and performance are available in our latest Sustainability report.


*Perfluorinated Compounds (PFC) are used in the semiconductor manufacturing processes and contribute to global warming.
