Forests are the natural treasure chests of the world, providing a host of ecosystem services that – and this needs to be said very clearly and up front – are paramount to ensuring economic progress and human well-being, not only locally but also at global scale. This new study asserts that any post-Kyoto climate convention negotiated in Durban and beyond must include text that clarifies the fundamental role of private engagement and investment in funding REDD+, as well as effective measures to tackle the fundamental drivers of deforestation by shifting behavior in the private sector towards sustainable land-use. The report highlights the huge costs for the world economy and the global environment of policy-makers coming short of fulfilling these criteria. This report (REDDy-Set-Grow Part II) further articulates the features which the private financial sector would like policy-makers to include in a new climate change treaty to summon sufficient funds.
