All figures are rounded to whole numbers, which may result in rounding differences.
1	Index 2015 = 100%
2	In 2025, the greenhouse gas (GHG) calculation methodology was updated. Consequently, the figures for 2024 and 2023 have been recalculated using the revised methodology and are restated in this table. Data for prior years remain as originally reported.
