National totals exclude all GHGs from the land use, land—use change and forestry sector.

Emissions from fuel ethanol are reported within the gasoline transportation subcategories.

The category Mineral product use includes CO₂ emissions from the use of limestone and dolomite, soda ash, and magnesite.

Note(s):

Classification according to United Nations Framework Convention on Climate Change^. Totals may not add up due to rounding.
