Google warned that reaching its climate goals was "getting harder" amid the AI boom, with the business reporting a 16% annual jump in its carbon emissions.
"Our AI infrastructure buildout is currently accelerating faster than the grid is decarbonizing," said Kate Brandt, Google's chief sustainability officer.
The company's report for 2025, released on Tuesday, came just a day before Amazon published its own figures, showing an 18% risecompared to 2024.
Put in a long-term perspective, Amazon, which emitted 80.85 million tons of CO2 equivalent last year, saw a 58% increase compared to 2019. Google, which had 18.8 million tons of CO2-equivalent emissions, saw an 82% rise in the same period.
Amazon's emissions are more than those of the entire country of Austria (71 million tons) or Greece (71.5 million tons) and less than the Netherlands (145 million tons), according to 2024 figures from the EU's Emissions Database for Global Atmospheric Research.AI fuels tech giants' emissions
