Could you build this?
Partial Metering API token calls via a proxy is standard, but producing legitimate 'audit-grade' carbon accounting requires verified datacenter energy models, grid carbon intensity datasets, and compliance with GHG protocol standards.
What it would actually take: Architecture requires a high-throughput API gateway/reverse proxy to intercept and meter AI token usage across providers. The hard part is the carbon conversion methodology: mapping token volume to specific GPU hardware architectures (H100, A100), querying regional hourly grid carbon intensity APIs (e.g., WattTime/Electricity Maps), and complying with GHG Scope 2/3 reporting frameworks. This requires sustainability domain knowledge and established lifecycle assessment methodologies.
