This paper describes the methodology and data used for the construction of a collaborative work tool focused on REDD+ projects and called ID-RECCO, which stands for ‘International Database on REDD+ Projects linking Economic, Carbon and Communities data’. ID-RECCO links 110 variables informing on several aspects of REDD+ projects: carbon certification, sources of financing, socio-economic expected impacts, project proponents and general features of the project. As of October 2014, we have collected data on 410 projects, 57 countries and 362 project proponents. This database is innovative in the sense it is the first time such a large amount of information is collected on REDD+ projects globally, in a format adequate for research purpose and analysis. It will be particularly useful for researchers who work on REDD+ issues, but it will also constitute a unique learning unit for project proponents and governments who are implementing REDD+ actions at different scales.
