The potential for Bus Rapid Transit to reduce transportation-related CO2 emissions

This article examines Bus Rapid Transit (BRT) as a near-term strategy for reducing CO2 emissions in a typical medium-sized U.S. city. The paper compares the expected CO2 emissions from three scenarios to meet the city's growth in work trips by 2011: a no-build option that relies upon private automobiles and a diesel bus fleet; building a light rail (LRT) system; and building a BRT system using 40-ft or 60-ft low emission
buses. The paper calculates a CO2 emissions inventory for each scenario and finds that BRT offers the greatest potential for greenhouse gas reductions, primarily because BRT vehicles generally offer lower CO2 emissions per passenger mile than LRT.
