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.

Greenly publishes 7 APIs on the APIs.io network, including alternatives API, live API, offsetProjects API, and 4 more. Tagged areas include Carbon Accounting, Carbon Footprint, Carbon Analytics, Greenhouse Gas, and GHG Protocol.

Greenly’s developer surface includes authentication, developer portal, pricing, documentation, support, engineering blog, tooling, and 45 more developer resources.
