The TEEB Synthesis Report Mainstreaming the Economics of Nature

The Economics of Ecosystems and Biodiversity (TEEB) study is a major international initiative to draw attention to the global economic benefits of biodiversity, to highlight the growing costs of biodiversity loss and ecosystem degradation, and to draw together expertise from the fields of science, economics and policy to enable practical actions moving forward.
"Mainstreaming the Economics of Nature" is the last of four reports produced by the U.N. Environmental Program over the past two years and aims to capture how habitats such as tropical forests and coral reefs contribute to countries' economic bottom lines. You can find many other TEBB reports in several languages here.
