🇬🇧Climate & Sustainability in United Kingdom

17 climate & sustainability providers in United Kingdom, publishing 16 APIs.

17 providers 16 published APIs 39 indexed documents

Climate & Sustainability in United Kingdom — 17 providers on the APIs.io network sit in both cohorts, and between them they publish 16 indexed APIs.

10 of the 17 publish at least one machine-readable API; 7 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: 6 emerging, 5 thin, 3 minimal, 2 strong, and 1 developing.

Leading by rating: UK Power Networks, Octopus Energy, Carbon Intensity API, University of Reading, National Energy System Operator (NESO), National Grid ESO, and 11 more.

Country membership is exact-tag only. A provider lands in United Kingdom when one of its own top-level tags names the country — there is no headquarters signal on the country axis, unlike the region axis which reads tag, provider-name pattern, and stated HQ. So this cell is a floor, not a census, and it understates by construction — a climate & sustainability company headquartered in United Kingdom that never tags itself is counted nowhere on this axis. The region cuts read the wider signal set and will generally hold more.

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