- Buffering Parcels: GIS Based Method for GHG Emission Analysis
Raef Porter, SACOG
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.
Measuring Greenhouse Gas Emissions with a Sustainability Tool

Simon Shoi, Southern California Association of Governments
With the recent passage of California Senate Bill No. 375, the need for an analytical tool that helps local planners in land use decisions is greater than ever. This presentation aims to introduce a Sustainability Tool and its use for the development of sustainable communities in Southern California region. A Sustainability Tool developed by Southern California Association of Governments is an ArcGIS based modeling and evaluation tool scripted by Python that enables users to visualize and evaluate the impacts of different land use scenarios on vehicle use and Greenhouse Gas emissions in real time. By demonstrating the benefits of sustainable land use strategies in reducing vehicle use and emissions, the tool is expected to play a central role in creating a sustainable land use strategy for the region through participation and consensus building.
Climate Change and Sustainable Communities
- Wed, Jul 14, 8:30AM – 9:45AM, Room 31 A
- GIS is helping municipalities, indigenous communities, and policy makers identify their sustainability goals and take practical steps to achieve these objectives. Learn how a variety of organizations are applying GIS to deal with the changing climate and plan sustainable communities.
- Planning For Climate Change – ClimateWise
Richard Nauman, National Center for Conservation Science and Policy
Our ClimateWise program uses GIS to incorporate climate modeling data in community-based climate change adaptation planning. Modeling efforts have produced a series of large, spatially explicit datasets projecting future climatic conditions. The volume of information produced by these efforts coupled with the technical difficulty of accessing the data, processing it, and displaying it in a GIS environment has limited their usefulness for non-technical audiences. We have developed Python scripts that use the built-in geoprocessing functionality of ArcGIS to access these files and produce cartographic and tabular output used in climate adaptation planning processes. When incorporated into a facilitated series of forums, these data have proven valuable communities creating climate change adaptation plans at the river basin scale. Our process integrates the needs of cultural, ecological, economic, social, and built sectors of communities and results in robust action plans that build resistance and resilience in human and natural systems.
Local Climate Change GIS-databased Visioning Tools for Community Decision-Making

Climate change has become the key topic in urban and landscape planning because today, planners have to decide on the mitigation and adaptation measures that future will bring into action. However, there is a gap between the state of research and its current consideration in planning. The reasons are the complexity of climate change impact and the uncertainties that are linked to it. In this context, GIS is a potential tool for capacity building. With regard to international case studies, GIS is used to identify the potential spatial consequences of different adaptation and mitigation scenarios. Especially, the model builder allows varying alternative scenarios, considering the impact of different adaptation and mitigation measures. The visualization using the globe metaphor illustrates the global context of local action.
