Environmental indicators
This section includes indicators and GRI Standard disclosures.
Our environmental data covers our 11 largest manufacturing sites, representing more than 95% of the overall environmental impact of the Company.
The methodologies used to calculate data are detailed in internal Company procedures, which are regularly reviewed during third-party environmental audits (EMAS, ISO 14001, ISO 50001, ISO 14064).
See ST site certifications table in business indicators.
ST follows the Greenhouse Gas (GHG) Protocol for managing its GHG emissions. The resulting CO2 emissions are reported according to recognized international standards, (reference – World Resources Institute (2004) GHG Protocol – A Corporate Accounting and Reporting Standard).
Scope 1 – Direct emissions resulting from operations
- Combustion emissions: World Resources Institute (2008) – GHG Protocol calculation tool for stationary combustion v.4.1
- PFC emissions before 2023: 2006 IPCC Guidelines for National Greenhouse Gas Inventories. 2007 IPCC fourth Assessment Report Climate Change. Table 2.14. Lifetimes, radiative efficiencies and direct GWPs relative to CO2 www.ipcc.ch
- PFC emissions from 2023: 2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories. IPCC, 2013: Climate Change 2013: The Physical Science Basis. Contribution of Working Group I to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change- Appendix 8.A: Table 8.A.1 Lifetime, Radiative Efficiency and Metric Values
Scope 2 – Indirect emissions resulting from purchased electricity
- World Resources Institute (2014) – GHG Protocol calculation tool for stationary combustion. v.4.8, GHG Protocol Scope 2 guidance
Scope 3 – Emissions resulting from travel and transportation
- Mobile Combustion GHG Protocol tool v.2.6
