Soot-free low-carbon city fleets

The transformation of the transport sector is essential for mitigating greenhouse gas emissions and improving human health. While current procurement plans for conventional diesel fleets can undermine efforts made towards improving air quality and taking action on climate, public vehicle fleets are highly suited to conversion and investments in clean technologies due to their high level of day-to-day visibility. The project is therefore supporting partner countries in converting their urban bus fleets and other public vehicle fleets in five major cities to soot-free, low-carbon technologies. The project is achieving this by working closely with local stakeholders.

State of implementation/results

  • Conduction of annual surveys to assess the knowledge of soot-free and zero-emission buses and needs for communication and training formats among local transit agencies, public officials, vehicle and infrastructure providers and other related stakeholders.
  • Developement of a seven-module training curriculum about the transition to soot-free and zero-emission urban bus fleet technology. The modules are being published as a series of videos on topics such as vehicle technologies, infrastructure consicerations, business and finance models (…;list=PLg8H8f2XVaFl_bAKRvGNObavgzVrcrH5T).
  • Completation of a retrospective analysis of global bus sales data in 2018, which highlights differences in bus powertrain technology by region and manufacturer and identifies leaders in zero-emission bus deployment internationally.
  • India:
    • In 2021, 390 electric buses were ordered, of which 30 buses were allready deployed in December 2021. The project supported efficient deployment of these buses by developing schedule optimisation programs to incorporate the additional charging times into the current bus schedules.
    • A performance evaluation Checklist has been developed to help the Bangalore Metropolitan Region Transport Corporation monitor the performance of operators in order to support the contract management.
    • The Bangalore Metropolitan Region Transport Corporation was supported in the procurement of 90 electric buses and 643 zero-emission Euro VI diesel buses. As a result of a local government resolution, the public bus fleet is to be expanded to 15,000 buses by 2030. By then only 100% zero-emission vehicles will be procured.
  • Indonesia:
    • In March 2022 Transjakarta placed the first 30 BYD K9 electric buses in service for the main BRT corridors (1 and 6).
    • Transjakarta has designated the bus-rapid-transit corridors 1 and 6 as corridors for the operation of e-buses.
    • With support of local partner institutions, a strategy was developed to promote electric mobility in the country. The focus of the strategy is on creating investment opportunities and synergies between already existing initiatives.
    • In July and September 2020, a series of online seminars was held on the topic of "electric mobility". This included the plans of various government agencies, the role of electric bus manufacturers and producers, and electricity prices for public transport.
    • Since April 2020, the development of a national policy paper on vehicle procurement for public bus fleets has been supported.
  • Mexico:
    • 9 e-buses are already circulating in the BRT System and 51 more are expected to arrive by the end of 2022.
    • There is ongoing collaboration with local governments to expand local clean vehicle policies and accelerate fleet replacement through higher standards and the use of better exhaust filters.
    • Until May 2021 a series of webinars on freight vehicle renewal was organised with the World Resource Institute.
  • Brazil:
    • Some studies have been published or are in process, for such as one about a Fleet Wide Deployment Strategy which summarizes baseline emissions, technology choice, infrastructure requirements, and purchase schedule scenarios for electrification of all the standard buses owned by Transwolff or one paper that analyses the telemetry data from two buses from the São Paulo pilot project.
    • In São Paulo, a bus company is currently being supported in developing a strategy to electrify its fleet.
  • China:
    • Completion of a study on the greenhouse gas reduction potential of introducing zero-emission city buses and heavy-duty vehicles in Hainan Province. The study will serve the province in the development of its New Energy Vehicle 2030 Implementation Plan.
