Notes:

1 National totals exclude all GHGs from the Land Use, Land-Use Change and Forestry Sector. CO2 from agricultural soils and non-CO2 emissions from forest fires, which were previously included in national totals, are now excluded.

2 CO2 estimates from cropland include about 16 Mt CO2 of annual emissions due to land conversion to cropland.

Totals may not add due to rounding
