GHGProof
GHGProof is an open source model designed to evaluate the impacts of land-use decisions on greenhouse gas emissions and energy consumption at the community scale. It has been developed by Sustainability Solutions Group, a Canadian workers co-operative, and has been widely used in British Columbia since 2008, with regular revisions and updates from SSG's GHGProof pages. Reviews of GHGProof and comparison to other modelling platforms may be found in references.
