Near-Term Transportation Energy and Climate Change Strategies: Interregional Transportation Related Greenhouse Gas Emissions Reduction Strategies.

摘要

The passage of California Assembly Bill 32 (the Global Warming Solution Act of 2006), and California Senate Bill 375 (which requires regions to develop strategies to reduce vehicular travel by incorporating land use change scenarios) provides targets and a framework for reducing greenhouse gas (GHG) emissions in California. Additionally, California Senate Bill 391 requires Caltrans to assess how the Metropolitan Planning Organization's Sustainable Communities Strategies (SCS) implementation will influence the configuration of the statewide multimodal transportation system needed to achieve a statewide reduction of GHG emissions to 1990 levels by 2020, and 80 percent below 1990 levels by 2050. The objective of this research effort was to provide Caltrans with tools to assist with prioritizing of which GHG emission reduction strategies for interregional travel California should focus on. Caltrans needed a better understanding of the potential magnitude of emissions reduction from strategies where data is available and developing level of confidence estimates for various strategies, and gauging the social/political acceptability of potential GHG strategies. Additionally, this research was to provide vital inputs, based on the current state of knowledge (in terms of elasticities and feasibility of various GHG reduction strategies), for the California Statewide Travel Demand Model which is a requirement for the California Transportation Plan (CTP).
