Incorporating Greenhouse Gas Emissions into the Collaborative Decision-Making Process

TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-C09-RR-1: Incorporating Greenhouse Gas Emissions into the Collaborative Decision-Making Process identifies where and how greenhouse gas (GHG) emissions and energy consumption fit into a conceptual decision-making framework, including key decision points.

The report presents background information on the role of GHG emissions in the transportation sector, factors influencing the future of emissions, GHG emissions reduction strategies, as well as information on cost effectiveness and feasibility of these reduction strategies. It also presents case studies to illustrate different scales and institutional contexts for GHG analyses.

A web-based technical framework, Integrating Greenhouse Gas into Transportation Planning, which was developed as part of SHRP 2 Capacity Project C09, provides information on the models, data sources, and methods that can be used to conduct GHG emissions analysis. The framework is part of the Transportation for Communities: Advancing Projects through Partnerships (TCAPP) website. TCAPP is organized around decision points in the planning, programming, environmental review, and permitting processes. TCAPP is now known as PlanWorks.

SHRP 2 Capacity Project C09 also produced a Practitioners Guide that presents information on how GHG emissions can be incorporated into transportation planning when using different types of collaborative decision-making approaches and includes an appendix with detailed technical information for GHG analyses.

An e-book version of this report is available for purchase at Amazon, Google, and iTunes.

In June 2013, SHRP 2 released a project brief on SHRP 2 Project C09.
