AKRF prepared close-out reports for New York City’s alternative vehicle and fuel programs funded by the Congestion Mitigation and Air Quality Improvement (CMAQ) program. The reports include analyses of the emissions benefits and cost effectiveness of all New York City programs since the CMAQ program’s inception.

Vehicles analyzed include compressed natural gas (CNG), diesel-electric hybrid, gasoline-electric hybrid, hydraulic hybrid, and fully electric vehicles, including light duty vehicles and trucks used by various City agencies.

Since there was no detailed guidance, AKRF developed the methodology for the CMAQ close-out analyses. Information on emissions was not available for some vehicle types analyzed, so emissions testing was performed by a subcontractor, Emisstar, and the test data then analyzed by AKRF.

Emission rates and fleet mileage data were used to calculate emissions for both alternative vehicles and those typically used by the City for the purpose of establishing the emission reduction benefits as a result of the vehicles purchased with CMAQ funding. In addressing greenhouse gas emissions, we also analyzed emissions associated with electricity use by electric vehicles. The reports included a comparison of emissions with and without the program, program funding rates, and cost-effectiveness.

The CMAQ programs analyzed include the earliest funded programs, initiated in early 1990s, as well as the most recent programs. To the best of our knowledge, these are the first close-out reports for CMAQ to be prepared.
