This report, prepared for the National Cleaner Production Centers (CNP+L) of San Jose, Costa Rica assessed the feasibility of using bio-diesel or bio-diesel blends in public transportation buses. There were three primary questions that this report addressed. First, what is the fuel efficiency of bio-diesel compared to diesel in public transit buses? Second, what is the cost difference for the use of bio-diesel versus diesel in the public transit sector of San Jose? Finally, what impact will bio-diesel have on the economy, environment, and society and how are these impacts interrelated? Our findings were used to assist CNP+L in making policy decisions regarding bio-diesel use in the public transportation system of San Jose.
