Show HN: Estimate the carbon footprint of your company's AI use (open data)
SOMA AI released a free calculator that estimates the CO₂e, electricity and water behind an organisation's use of AI tools such as ChatGPT, Microsoft 365 Copilot, Claude, Gemini, GitHub Copilot and AI APIs, broken down by team and tool with a range. It uses SOMA AI's published inference factors (DOI 10.5281/zenodo.23371447, method in peer review), based on ML.ENERGY Leaderboard v3 energy per token on H100 GPUs, a PUE of 1.2 and regional grid carbon intensity from Ember 2023 and US EPA eGRID 2023. A first estimate needs only tools, people and usage frequency (Tier 2b), with message counts or token data replacing defaults, and results are reported as Scope 3 Category 1 location-based.
