MCPs › Data & APIs › GreenCalculus
Look up greenhouse-gas emission factors and run standards-based carbon calculations (activity-based, embodied EN 15978, PCAF financed emissions) — every result returns with its exact source cell and data version, so your agent hands back sourced, citable numbers instead of a guess. 13,000+ factors across 50+ categories (grid, fuels, freight, refrigerants, AFOLU, CBAM, construction materials, spend-based EEIO, digital). Free tier, no card.
