Greenhouse gas (GHG) emissions from agriculture together with forestry (including land-use changes (LUC)) are responsible for nearly 30% of global anthropogenic emissions (IPCC, 2007), but the mitigation potential of these sectors is significant.

In order to test and develop methods, the study evaluates the effect of a land-use policy known as the rural environmental registry (CAR) on the reduction of deforestation rates in the Brazilian Amazon rainforest.
