Measuring The Invisible: Porto Alegre Case Study

The study evaluates transport interventions in Porto Alegre, Brazil, finding 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.

• The implementation of a Bus Rapid Transit (BRT) system in Porto Alegre is projected to reduce emissions by 25-31 thousand tonnes of CO2 annually when compared to a business-as-usual scenario that includes fare integration.
• Implementing a fare integration scheme on its own, without the BRT system, may lead to an increase in emissions.
• The use of emission control technologies and cleaner fuels would be significantly impactful if applied to bus fleets with high annual mileage, specifically the metropolitan or municipal fleets.
