Coverage by country

What a score of 13 actually means

The thirteen families are the ones a corporate greenhouse-gas inventory normally has to fill: grid electricity, market-based electricity, transmission and distribution losses, stationary fuel, mobile combustion, well-to-tank, district heat and steam, business travel, employee commuting, hotel stays, waste, water, and spend-based screening.

A filled dot means at least one factor exists in that family for that country. It is deliberately not a depth measure — a country with a single national grid figure scores the same on that family as one with per-subregion values, because the question this table answers is “is there anything here at all”, and that is the question that decides whether you can start.

Why most countries are grid-only

Because that is what the world publishes. National statistical offices and energy regulators produce electricity intensities almost everywhere; almost nobody publishes national per-passenger-kilometre business travel factors, and hotel and water factors are rarer still. The pattern in this table is mostly a map of what governments choose to measure, not of what we have got round to ingesting.

Where we know which of the two it is, the gap is recorded and classified in the absence register — whether no publisher issues it anywhere, a named publisher exists and it is our backlog, or we found it and declined.
