How This Month Is Measured
- Coverage. 84 countries reported October 2025. 84 of them also have October 2024, and those 84 are the like for like set behind every figure above. Together they made up 91% of world demand in 2025. A month is published only when at least 10 countries and 60% of world demand are covered.
- Not a world total. These sums cover the reporting countries only.
- Carbon intensity. The figure for the group weights each country's monthly intensity by its generation; country rankings use Ember's own monthly intensity.
