What the publisher changed
Yale Center for Environmental Law & Policy recomputes its whole history each edition, so the earlier figures here are the current ones for those years, not the numbers printed at the time.
Coverage
177 countries in the 2026 edition. Only the current edition is stored.
Limitations
Yale rebuilds indicators and weights between editions and recomputes the back-series, so ranks from earlier editions are not comparable and are deliberately not shown here. Large, fast-industrialising countries score poorly on per-capita and emissions-weighted measures by construction.
