How This Month Is Measured

  • Coverage. 71 countries reported May 2026. 71 of them also have May 2025, and those 71 are the like for like set behind every figure above. Together they made up 88% 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.
