2. All estimates, excluding biomass, have been converted into thermal equivalents with an average factor of 38.5%.

3. These activities include deforestation, afforestation, changes in agricultural management, and other anthropogenic land-use changes that result in a net flow of GHGs to or from the atmosphere. They exclude natural biogenic emissions and emissions that are not related to anthropogenic activity such as CO2 from volcanoes or volatile organic compounds from forests.

4. We include deforestation in this category of emissions even though this is a process of land-cover change rather than a land-use activity.

5. East Asia including China, Southeast Asia, and the Indian subcontinent.
