A wide range of tools and resources is available to assist decision-makers and their advisors in planning for REDD+ implementation. As these materials have been developed with different problems and decision-making contexts in mind, it can be difficult to identify the ones that are most suitable in a specific situation. This document is a guide to some of these tools and resources, with a particular focus on those which take account of the multiple values of forests and can support the design of REDD+ interventions that provide climate change mitigation as well as other social and environmental benefits.
