ST is committed to reducing its direct and indirect greenhouse gas emissions, including PFCs, from its manufacturing and other business operations, in accordance with the Kyoto Protocol.

 
Our GHG, air emissions management objectives

-  Reduce PFC's emissions by 30% from 2010 to 2020

-  Decrease CO2 indirect emissions

-  Compensate our direct emissions
   through reforestation programs


> 40%
of direct emissions compensated
by our forests

 

Even though the semiconductor industry is a relatively minor contributor to overall GHG emissions, it emits high Global Warming Potential (GWP) substances. We began setting ambitious targets in the 1990’s to reduce perfluorinated compounds (PFCs) in our manufacturing processes, as part of our commitment to outpace national and international regulation and emission reduction targets.

Since 2006, ST has participated annually in the Carbon Disclosure Project (CDP) evaluation of our carbon emissions, energy use, reduction and risk management related to climate change.
In 2016, we reached the B level.

Management of GHG emissions
ST manages its GHG emissions through a strategy that takes all aspects of the value chain into consideration and seeks to work with stakeholders to find alternative solutions. We measure, manage and report our direct and indirect emissions in accordance with the GHG Protocol.

Scope 1
Direct emissions resulting from combustion emissions and Perfluoro-compounds (PFC) which have a very high Global Warming Potential
 
ST is committed to the World Semiconductor Council’s 2020 targets on climate change, including its goal to reduce PFC normalized emissions by 30% from 2010 to 2020. To reduce our emissions we continue to implement projects to install PFC abatement systems and develop greener manufacturing techniques. For more information, please read the latest WSC joint statements. 
During day-to-day site activity, internal experts work on optimizing manufacturing processes to reduce the need for chemical substances and to replace high GWP gases with lower or GWP-free alternatives.To offset the remaining direct emissions, ST has developed a number of reforestation programs.
Scope 2
Emissions resulting from energy use

Scope 3
Emissions resulting from transportation
ST actively manages the social, safety and environmental impacts resulting from transportation and logistics for products, employees commuting and business travels, considering overall efficiency and reduction of CO2 emissions.


Climate change adaptation

In addition to climate change mitigation, ST has also developed mechanisms to anticipate and adapt to potential risks related to climate change.

Business Continuity Planning (BCP)
Coordinated at corporate level and implemented by each site, this program defines how ST will manage major incidents via the assessment of business risk, emergencies preparedness and disaster recovery.

Analysis of climate change related risks 
In 2012, ST conducted a more detailed risk analysis of these risks (phase 1 of BCP) with the help of an external consultant.  The scope of this assessment covered our entire value chain, from raw material production and sourcing, to transportation, direct operations, use of our products and their end-of-life. 

ISO 14001 and EMAS
All our manufacturing sites are ISO 14001 certified and EMAS validated, which means that they have evaluated their environmental risks and impacts and have integrated them into management systems.

Involvement of suppliers and subcontractors
ST works in close collaboration with supply chain partners and strongly encourages them to adopt environmental management programs. Our supplier requirements include strict environmental criteria that are regularly updated and communicated. For more information, see our Supply Chain Responsibility page. 

In our Energy and Sustainable Technology sections, we also explain how we address climate change when managing these activities.

Our objectives and performance are available in our latest Sustainability report.
