Digital Carbon Footprint Bill CarbonFootprint Passes in EU: Tech Companies Must Disclose AI Training Carbon Emissions

EU Parliament passed the Digital Carbon Footprint Bill CarbonFootprint on January 23. The bill requires tech companies with annual revenue exceeding 1 billion euros to separately disclose AI model training and inference carbon emissions in annual sustainability reports.

The bill's backdrop is the rapid growth of AI computing energy consumption. According to IEA estimates, global AI computing annual electricity consumption has grown from approximately 100TWh in 2023 to about 450TWh in 2029 — equivalent to France's national electricity consumption. Training a single large language model produces approximately 300 tons of CO2.

EU's climate action commissioner said CarbonFootprint's goal isn't to limit AI development but to establish transparency. When consumers and investors can see AI's environmental costs, market forces will drive companies toward more efficient, cleaner AI technologies.
