"Which AI Chatbots Have the Highest Emissions? Here's What We Know" — Bloomberg (via Google News) · AI & Technology
Bloomberg has published an analysis comparing the of major AI chatbots, including Claude, DeepSeek, and OpenAI's models. The piece notes that the AI industry largely keeps its carbon footprint data private, so the analysis compiles what is publicly known or can be estimated about each chatbot's energy use and emissions. It likely covers both training and inference (per-query) emissions, drawing on prior studies and company disclosures.
The claim is based on a Bloomberg news article, which is a secondary journalistic analysis, not a primary scientific paper or official dataset. Bloomberg is a reputable outlet, but the underlying emissions figures are estimates from various sources (e.g., academic studies, company reports) that may have different methodologies and uncertainties. The article itself acknowledges the industry's lack of transparency, so the numbers should be treated as approximate.
This is genuinely new reporting, published on November 8, 2026, and not a resurfacing of older material.
We covered the broader trend of AI's soaring energy use in July 2024, when NPR reported that a ChatGPT query needs about 10 times the electricity of a Google search, and that Google and Microsoft's emissions were rising sharply due to AI.
