The Manual is designed to be used by carbon project proponents aiming for validation under the CCB Standards, or other multiple-benefit carbon standards. The NGOs involved in this initiative believe that a combination of credible social impact assessment methods and robust standards for verifying the co-benefits provides an important way of promoting positive social outcomes of land-based carbon projects. The Manual is Version 1.0, since the idea is to ‘field test’ it over the coming months and, based on user experience, peer review, and other feedback, bring out Version 2.0 in early 2011.
