Initial situation 

Public fleets provide key local services and serve as important targets for increasing investment in clean, low-carbon engine technologies. Ongoing efforts to expand public fleets using conventional diesel engine technology may harm urban air quality and slow the deployment of low-carbon technologies, particularly in rapidly developing economies.

The objective of this project is to realign urban bus fleets and other specialized public fleets toward a soot-free, low-carbon technology pathway in five megacities and to scale up this model for technology deployment at the national level. The project implementers will provide technical capacity to city officials to define and carry out this transition. Early and rapid technology transitions in selected fleets will deliver improved air quality and public health benefits while also avoiding the climate impacts of black carbon and other short-lived climate pollutants. Through its activities, the project contributes to the implementation of the Paris Agreement, the SDGs, the New Urban Agenda, and the Addis Ababa Action Agenda.
