Acre State in Brazil is at the forefront of efforts to institutionalize jurisdictional-scale policies that aim to reduce emissions from deforestation and forest degradation (REDD+). Given limited REDD+ funds and uncertain returns from alternative land uses, this paper estimates the minimum incentive payment Acre's government would have to pay forest landowners in each of its 22 municipalities to ensure forest conservation. Despite lower profits but with lower conversion costs and more stable returns over time relative to corn and coffee production, cattle pasture generates the highest returns in 19 municipalities. Municipalities are ranked according to their relative policy costs, a ranking which is compared to the distribution of forest carbon stocks across Acre. Finally, the relative cost per tonne of carbon is derived, which enables the identification of a group of 13 municipalities with the greatest potential for 'carbon bang' for a given 'buck'.
