16% of emissions from fossil fuel sources. Tropical deforestation in Africa, Asia,
and South America are thought to be the largest contributors to emissions.
However, in the United States and Europe, changes in land use that are
associated with human activities have the net effect of absorbing CO 2 , partially
offsetting the emissions from deforestation in other regions.
