The cutting of carbon emissions from deforestation in half across the tropics would keep 1.135 billion tons of carbon out of the atmosphere. A new peer-reviewed study on carbon emissions which appears in the December edition of the scientific journal Global Change Biology, assembled the most up to date data to generate a map of the amount of carbon in tropical forest to establish bechmarks for average annual carbon emissions caused by deforestation in the tropics. Daniel Zarin, co-author of the study and director of programmes of climate and land use alliance says the new study finds big reductions from Brazil largely offset by increases in other tropical forest countries.
