Global warming places life on earth in danger, threatening fresh water, food, and energy supplies. Greenhouse gas (GHG) emissions are the primary cause of global warming. Carbon dioxide (CO2), methane (CH4), and nitrogen oxides (NOx) are GHGs produced by the combustion of oil, fossil fuels, and other sources.
The technology and communication industry accounts for approximately 2% to 3% of worldwide greenhouse gas emissions. GHG emissions are produced by industry operations such as energy consumption, product manufacture, and product use. Digital technology, according to the International Telecommunication Union, has the potential to reduce world carbon emissions by roughly 17%. Technology companies can help other industries improve their operational efficiency, cutting GHG emissions.
Semiconductor companies have set ambitious targets for reducing emissions to limit global temperatures from rising to 1.5°C. Most semiconductor manufacturing emissions fall into scope 1 or scope 2 categories. A large proportion of GHG emissions by Semiconductor companies comes from their fabrication plant.
GHG Emissions by Leading Semiconductor Companies
Samsung Electronics Co Ltd (Samsung) reported total GHG emissions of around 29.5 million tonnes CO2 equivalents (MtCO2eq) in 2020, down 3% from 2019. Samsung reported that from 2020 all its worksites in the US, Europe, and China would be 100% powered by renewable energy sources. The company is committed to decreasing the amount of GHG emissions in the product use phase.
Intel Corp (Intel) designs and develops technology products and components. The company’s product portfolio comprises microprocessors, chipsets, embedded processors and microcontrollers, flash memory, graphic, network and communication, and conferencing. The company reported total GHG emissions of 35.4 MtCO2eq in 2021, a decrease of 2% from 2020.
Taiwan Semiconductor Manufacturing Co Ltd (TSMC) is a provider of semiconductor foundry services. The company reported total GHG emissions of 17 MtCO2eq in 2020, an increase of 10% from 2019. In 2020, TSMC's scope 2 emissions accounted for 48% of its overall GHG emissions (8.2 MtCO2eq). In 2020, the company's Scope 1 emissions were up by 18%, and Scope 3 emissions increased by 4%.
