Tropical deforestation contributes an estimated 12-17% of global greenhouse gas emissions. Under a rapidly emerging international policy mechanism called REDD+, developing countries that reduce emissions from deforestation and forest degradation below agreed reference levels would be eligible for payments from developed countries through carbon markets or funds. In this course students will gain an in-depth understanding of REDD+, and will gain practical experience applying the internationally used OSIRIS economic modeling tool to current issues in international and national REDD+ policy design and presenting technical analyses in mock policy settings.
