This document summarizes lessons learned from Brazil and Peru's efforts to implement REDD+ benefit sharing policies and programs. Key points include: 1) REDD+ requires large compliance costs that may reduce net financial benefits, so benefit sharing helps distribute these costs in an equitable way. 2) Brazil has effectively reduced deforestation through command-and-control policies but may need complementary incentive programs to remain politically viable. 3) Peru's existing PES program could improve cost-effectiveness and equity by better targeting payments based on opportunity costs and threat levels in different areas. 4) Political decisions around benefit sharing programs are often more motivated by welfare and distributional goals than environmental effectiveness.
