These, I think? http://www.greencampus.harvard.edu/green_projects/afvp/alt/cng.pdf A Fresh Look at CNG: A Comparison of Alternative Fuels August 13, 2001 Abstract: This report describes the current alternative fuel technologies and their impacts on global warming and urban air quality. Compressed natural gas (CNG) is compared to both diesel and gasoline in terms of greenhouse gas emissions, urban air quality, and cost. This report finds that CNG is the least preferable alternative to diesel and gasoline from the standpoint of greenhouse gas (GHG) emissions and cost-effectiveness.

Recommendations are made to immediately switch the diesel busses to 100% biodiesel during the spring, summer, and fall seasons. A mixture of 20% biodiesel is recommended during the winter. This report finds that the mini shuttles could be replaced with hybrid shuttles. The purchase of an electric or fuel cell vehicle is urged as a PR move for Harvard and as a demonstration of the feasibility of these promising technologies.
