        Climate Change

        The Atlanta region is facing many factors that can potentially drive a rise in greenhouse gas (GHG) emissions at a time when national policies are stressing the reduction of all GHG emissions.  ARC has begun to consider strategies for reducing transportation-based GHG emissions and is evaluating the role these strategies might play in Plan 2040.

        Regional planning for climate change is gaining more attention across the country. Hundreds of local governments, including several here in the Atlanta region, are taking steps to reduce their greenhouse gas emissions. While the debate on climate change continues, the benefits of reducing harmful emissions extend beyond adapting to a changing climate and to new federal regulations. Taking appropriate actions now can help alleviate congestion and improve public health. PLAN 2040 contains strategies that lead to reductions of primary pollutants, as well as CO2 emissions.

        Transportation and Land Use Scenarios

        Five scenario tests incorporating different land use strategies, as well as the new CAFE standard for fuel economy were analyzed for future impact on CO2 emissions and compared to 1990 conditions.  All 2030 scenario tests still result in an increase of at least 50 percent in CO2 emissions.

        ARC/FHWA Joint Climate Change Workshop

        ARC was selected by FHWA as one of five agencies nationwide to host a climate change scenario planning workshop in October, 2010.  The workshop brought together local, state and national stakeholders to discuss the role of scenario planning, climate change messaging, and future tools for quantifying CO2 emissions. 

        The information stakeholders provided will be used by FHWA to help develop a guidebook on strategies for reducing greenhouse gas emissions. The material will be incorporated into a web-based calculator to estimate the potential emissions reductions associated with various strategies.
