Energy & Climate Change
Manufacturing semiconductors requires energy and certain substances which contribute to global warming and ozone depletion.
ST is committed to decreasing Greenhouse Gas (GHG) emissions and to reducing its carbon footprint. This has led us to adopt approach to reduce our GHG emissions and to implement energy-efficieny programs along with the purchase of renewable energies.
26% of energy purchased comes from renewable sources in 2017 |
44% of our direct emissions compensated by our forests in 2017 |
Energy
Manufacturing semiconductors requires energy to run the manufacturing equipment but also to maintain the stringent environmental conditions (cleanroom temperature, humidity, air quality).
For more than two decades, ST has been decreasing its energy usage, reducing its costs and gaining efficiency through continuous upgrades of existing equipment and improvement of manufacturing processes. These energy-efficiency programs have already halved our energy consumption per production unit. All our energy-intensive Front-end sites have been ISO 50001-certified since 2013.
Part of our strategy to reduce our carbon footprint is also to increase the share of renewable sources in our energy mix.
Climate Change
Mitigating our direct emissions
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 develop projects to install PFC abatement systems and define greener manufacturing techniques. To offset the remaining direct emissions, ST has developed a number of reforestation programs.
Considering emissions related to transport
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.
