Cambridge Systematics Announces Release of “Moving Cooler” Research Study on Reducing GHGs (July 28, 2009)

Cambridge Systematics, Inc., along with our study partners, is pleased to announce the publication of Moving Cooler: Transportation Strategies to Reduce Greenhouse Gas Emissions, a groundbreaking report that ties transportation efficiency, greenhouse gas (GHG) reduction strategies, and consumer savings to GHG reduction goals.  Moving Cooler provides objective information that can help shape effective, integrated approaches for reducing GHG emissions nationally, regionally, and locally, while meeting broader transportation objectives as well.

Reducing transportation-related GHG emissions will be critical to meeting national goals. Transportation contributes roughly 28 percent of the United States’ total GHG emissions, and between 1990 and 2006, growth in U.S. transportation GHG emissions represented almost one-half (47 percent) of the increase in total U.S. GHGs.

Advances in both vehicle and fuel technologies must and will play a critical role in reducing the carbon footprint of transportation. However growth in travel and continued population growth will offset some of the gains achieved through technology improvements.  Transportation strategies that affect the amount of travel, how people and goods travel, and system efficiency also must be considered.

Bundling Strategies Can Increase GHG Reductions

The Moving Cooler analysis assesses the effectiveness of almost 50 strategies that could reduce GHG emissions by reducing the amount of vehicle travel that occurs, by inducing people to use less fuel-intensive means of transportation (e.g, walking, bicycling, riding in a bus or train, or carpooling), or by reducing the amount of fuel consumed during travel through transportation system improvements. Strategies are first assessed individually, and are then combined into strategy bundles to illustrate the potential cumulative effects that could be achieved.

“While advances in fuels and vehicle technology will be critical to reducing GHG emissions from transportation, the Moving Cooler analysis demonstrates that additional GHG emission reductions can be achieved by bundling transportation strategies,” said Lance Neumann, President of Cambridge Systematics.  “These bundles can be designed to support transportation and economic objectives while also contributing to GHG reductions.”

The strategies considered by Moving Cooler are grouped into nine categories, as follows:

Moving Cooler To Inform Policy Debate

Moving Cooler does not advocate for any particular approach to reducing GHGs.  Rather, it presents estimates of how much GHGs could be reduced under a range of assumptions about how they are implemented – from expanding current practice more quickly and broadly to major changes in public policy and regulation.  The intent is to further inform public policy debate at the national, regional, and local levels by providing insight into the magnitude of GHG reductions that might be possible over a wide range of “what if” scenarios.

Steering Committee

Led by the Natural Resources Defense Council (NRDC), the independent study is co-sponsored by the American Public Transportation Association (APTA); Environmental Defense Fund; U.S. Environmental Protection Agency (EPA); Federal Highway Administration (FHWA); Federal Transit Administration (FTA); Intelligent Transportation Society of America (ITSA); Kresge Foundation; Rockefeller Brothers Fund; Rockefeller Foundation; Shell Oil; Surdna Foundation; Funders Network for Smart Growth; and the Urban Land Institute.
