That is the conclusion of a study published in December 2024 by a consulting firm: about 50 million tonnes of CO2e in 2023, against 51.67 million for Greece. The estimated total stays below Greece's, even though La Libre Belgique headlines a larger footprint. The total extrapolates to the whole world a calculation made for 3 countries, at 2.921 gCO2e per minute, or 175 g per hour (our conversion), which is 2.7 to 4.9 times the references of the International Energy Agency, the Carbon Trust and ADEME (our calculation). According to the study page, about 2 g of the 2.9 come from data centres; we did not find the source of this value. TikTok disputed this result and, according to La Libre Belgique, was not publishing its emissions at the end of 2024. Without published data on TikTok's servers, this total cannot be verified.
