The United Nations’ digital agency says that operational carbon emissions for the world’s top tech companies rose an average of 150 percent between 2020 and 2023 as investments in artificial intelligence (AI) and data centres drove up global electricity demand.
Operational emissions for Amazon grew 182 percent in 2023 against 2020 levels, while emissions for Microsoft grew 155 percent, Facebook and Instagram owner Meta grew 145 percent, and Google parent company Alphabet grew 138 percent over the same period, according to the UN’s International Telecommunication Union (ITU).
