Greenly

Greenly is a Paris-headquartered (with offices in London and New York) carbon accounting platform focused on small and mid-sized businesses, helping companies measure, reduce, and report their greenhouse-gas emissions across Scope 1, 2, and 3. The platform automates carbon footprint calculations from accounting, expense, supplier, energy, and cloud data; produces regulator-aligned Bilan Carbone, GHG Protocol, CSRD, CBAM, EUDR, SBTi, CDP, TCFD/IFRS, EcoVadis, and California climate disclosure deliverables; supports product-level LCA; recommends supplier alternatives; and offers a marketplace for verified carbon-offset projects. Greenly also exposes a developer-facing Carbon Analytics REST API (v1.5, hosted at api.greenly.earth) historically built by Offspend, which banks and fintechs use to enrich bank-card transactions with per-purchase CO2 emissions, classify spend into purchase categories, surface lower-carbon alternatives, and book offset volumes against vetted projects — sandbox and production environments are available with API-key authentication on request to contact@greenly.earth.
