Environmental benefits of alternative fuels and advanced technology in transit
This analysis, Environmental Benefits of Alternative Fuels and Advanced Technology in Transit, summarizes the findings of work done to estimate the level of pollutant emissions produced by the current national transit bus fleet and to evaluate the potential reductions that could be achieved by greater adoption of alternative fuels including CNG, LNG and biodiesel, and advanced vehicle technologies such as hybrid electric drive systems. The report estimates the total annual emissions from the U.S. transit bus fleet as it existed in 2003, the emission impact of planned bus procurements, and considers hypothetical scenarios in which
