Measuring The Invisible: Porto Alegre Case Study

A case study on Porto Alegre's planned transport interventions finds that a BRT system could reduce annual CO2 emissions by 25-31 thousand tonnes compared to a business-as-usual scenario with fare integration, whereas fare integration alone might increase emissions.

• Porto Alegre is planning to implement a fare integration scheme and a Bus Rapid Transit (BRT) corridor to increase bus ridership and reduce the number of terminals and buses in the city center.
• Estimates indicate that the BRT system would lead to an annual reduction of 25-31 thousand tonnes of CO2 emissions compared to a business as usual scenario that includes fare integration. Conversely, implementing fare integration by itself may lead to an increase in emissions.
• Analysis suggests that emission control technologies and cleaner fuels would provide a significant impact if used for fleets with high annual mileage, specifically the metropolitan or municipal bus fleets.
