Climate & Sustainability in United Kingdom & Ireland

38 climate & sustainability providers across United Kingdom & Ireland, publishing 18 APIs.

38 providers 18 published APIs 49 indexed documents

Climate & Sustainability across United Kingdom & Ireland — 38 providers on the APIs.io network sit in both cohorts, and between them they publish 18 indexed APIs.

12 of the 38 publish at least one machine-readable API; 26 publish nothing indexed at all. That split is the first thing worth reading here — a vertical can be well represented in a market and still have almost no programmable surface.

By Kin Score band: 16 minimal, 11 emerging, 6 thin, 2 strong, and 1 developing.

Leading by rating: UK Power Networks, Octopus Energy, Altruistiq, University of Reading, Emitwise, National Energy System Operator (NESO), and 32 more.

Region membership is derived from three explicit signals — a provider tag, a provider-name pattern, or a stated headquarters in the provider’s own description. This is a map of stated headquarters, not of markets served.

This page is the intersection of two independently computed cohorts: United Kingdom & Ireland and Climate & Sustainability. A provider appears here only when it is already a member of both. United Kingdom & Ireland membership is matched on tag, name pattern, stated HQ, so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.
