Queretaro, a historic city in the center of Mexico named a United Nations World Heritage Site, faces the predicament of fast growing medium-size cities – a need to upgrade its public transportation system to control rapidly rising motorization rates and congestion levels.

EMBARQ/WRI worked with the city of Queretaro to quantify the emissions from the existing bus system, and showed that introducing a Bus Rapid Transit (BRT) system and improving the efficiency of the bus network could yield extensive emissions reductions. Introducing alternative fuel and vehicle and emission control technologies yielded little additional reductions.
