Year 2011 saw existing forest carbon standards across the world launch new or revised methodologies, contract new projects and issue verified credits. Given the breadth and scope of issues covered by REDD+, links between forest carbon standards and other existing standards such as FSC and commodity roundtables’ standards are being explored and complementary socio-environmental standards continue to be initiated. This brief provides an update on these standards and an updated consolidated comparison table of key features of all standards. Please see FCA Brief No. 3 for an earlier standards review up to March 2011. We only focus on standards that are applicable for forest carbon activities in Asia.
