Practitioners Guide to Incorporating Greenhouse Gas Emissions into the Collaborative Decision-Making Process. The Second Strategic Highway Research Program.

摘要

The Practitioners Guide identifies steps in the transportation planning and environmental review process where greenhouse gas emissions could be considered and at what scale. The Practitioners Guide uses the decision points in the transportation planning and environmental review process from TCAPP to structure the information and link the scale of greenhouse gas analysis to stages in planning and environmental review. Finally the appendices to the Practitioners Guide contain data useful for conducting greenhouse gas emissions analysis, a compendium of tools, references to carbon calculators, life cycle fuel and emissions estimates, and other resources. This report provides background information to aid in understanding the issues, a summary of the state of the practice, a framework for conducting greenhouse gas analysis, a description of tools and data requirements, and an overview of the cost-effectiveness of various strategies. Eight short case studies are included to demonstrate the state of the practice by state departments of transportation, metropolitan planning organizations, and other units of government. Workshops were conducted in four states to vet the framework and the methods. The report and Practitioners Guide provide a structure to aid transportation professionals in coping with the greenhouse gas emissions issue, clarify the types of mitigating actions available to a transportation agency, and provide methods and data for analysts.
