AbstractBuffering Parcels: GIS Based Method for GHG Emission AnalysisTrack: Climate Change Author Like many of the 18 MPO's in California, Sacramento Area Council of Governments (SACOG) is developing the technical capacity needed to implement SB375, which is part of AB32, the State's greenhouse gas (GHG) reduction policy. SACOG creates and analyzes land use and transportation at parcel level to quantify transportation-related GHG emissions. Parcels are used, as opposed to zones, because they better capture the relationship between land use and transportation. In place of zones, SACOG buffers parcel/point land use data, and the resulting buffered files are used in the travel demand model. Once modeled, outputs are mapped to show where emissions are highest. In the Sacramento region, these maps show a correlation between the built environment (e.g. distance from employment centers) and GHG emissions. SACOG hopes similar GIS and modeling techniques are integrated into planning processes in other regions around California to help implement GHG reduction policies.
