What this topic does not measure
Air quality and biodiversity are not keys, because the site does not yet hold data for them that passes every test. Forest cover, farmland, farm emissions and the renewable share of electricity are published here as context. Exposure to natural hazards belongs to Risk & Resilience.
How the Environment & Sustainability standing is decided
A standing is this site’s ordering, named with its edition — never a publisher’s rank. 4 key statistics vote, one vote each; every country’s published value becomes a place within that key’s own field, the places are averaged, and the average is never published. A country needs 2 of the 4 keys to be placed.
