Viridis GHG Ledger

GHG Ledger turns explicit activity records (fuel, electricity, refrigerants, starter Scope 3 categories) into a deterministic greenhouse-gas inventory: per-line CO2e, Scope 1/2/3 and category rollups, location- and market-based Scope 2, the exact emission factors and sources used, and an audit hash anyone can recompute with verify_result. No inference and no guessed factors: anything outside the bundled factor pack (EPA, eGRID, UK DESNZ, IPCC AR6) is returned as indeterminate rather than estimated. Factor tables, classification and verification are free; 10 inventory calculations per day are free, then $1.00 each, payable by card or USDC, or covered by a monthly seat. It calculates supplied data; it is not accounting or assurance advice.
