The aim of the Heavy-Duty Diesel Initiative of the Climate and Clean Air Coalition is to virtually eliminate black carbon and fine particulate emissions from the on-road vehicle fleet by 2030. The Soot-Free Urban Bus Fleets Project puts this aim into practice with a focus on eliminating diesel black carbon emissions from coach and transit buses in 20 megacities. The cities targeted are: Abidjan, Accra, Addis Ababa, Bangkok, Bogotá, Buenos Aires, Casablanca, Dar es Salaam, Dhaka, Istanbul, Jakarta, Johannesburg, Lagos, Lima, Manila, Mexico City, Nairobi, Santiago, Sao Paulo, and Sydney. These cities all have a population of 3 million or greater, have access to a wide range of fuel quality, are geographically disperse, and at the time of project initiation had no requirements for soot-free emission in the urban bus fleet.
This report summarizes the major activities, policy milestones, technical developments, key challenges, and lessons learned over the course of this project.
