A Global Analysis of the Cost-Efficiency of Forest Carbon Sequestration Environment Working Paper No. 185

The paper proposes a ranking of the countries where forest carbon sequestration is the most cost-efficient among 166 countries for which data are available. Taking into account the main cost factors leads to a more nuanced ranking of the countries to be favoured for cost-efficient forest carbon sequestration compared to the assumption that these would always be in tropical areas with high rainfall. The ranking reflects the differences in the opportunity cost of land use and labour cost (production costs), the quality of the business environment (transaction costs), natural conditions (forest productivity), wildfire risk and the avoided GHG emissions from alternative land use. Cost-efficiency also depends on the type of forest project (afforestation, reforestation or forest conservation) and how private (wood harvest) and non-private (environmental and social) co-benefits are counted.
