Abstract for: Decarbonizing the public bus fleet in the city of São Paulo until 2038
In 2018, the city of São Paulo, Brazil enacted a law setting ambitious goals for the city's public bus transport CO2, particulate matter, and NOx with a deadline for reaching the target in January 2038. This encompasses a rapid technological transition of diesel-based buses towards cleaner options such as zero-emission or low-emission vehicles. However, for this transition to take place, decision-makers need to be aware of the technologies combination that can bring them closer to the legislation imposed. Therefore, this paper seeks to assess the goal imposed by the law, analyzing the interaction between biodiesel, electric, hybrid, biomethane, and natural gas technologies to achieve reductions in CO2, PM, and NOx.
