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 supported 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 achieved 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 were 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. The project supported efficient deployment of these buses by developing schedule optimisation programs to incorporate the additional charging times into the current bus schedules.
    • 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 October 2022, a decree establishing fleet mandates for electric bus adoption to 2030 was enacted. This decree will secure that new bus purchases are electric and how to fund it. The targets are: 50% of Transjakarta buses are EVs by 2027, and 100% by 2030.
    • In March 2022 Transjakarta placed the first 30 electric buses in service for the main BRT corridors (1 and 6).
    • 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.
  • Mexico:
    • In August 2023, 20 new electric buses were introduced, which will serve bus line 4 after initial test runs.
    • On 20 February 2023, Metrobus and the Mexico City Government announced the operation of the fully electric Bus Line 3.
    • In December 2022, a study was published on the performance analysis of electric buses in Mexico City (…).
    • Until May 2021 a series of webinars on freight vehicle renewal was organised with the World Resource Institute.
  • Brazil:
    • In December 2022, a study on the performance analysis of electric buses in São Paulo was published (…).
    • In São Paulo, a bus company was supported in developing a strategy to electrify its fleet.
  • China:
    • In August 2023, the Hainan provincial government released the 2023-2030 New Energy Vehicle Development Action Plan. This Action Plan sets a new set of specified and strengthend targets for vehicle sales and stock.
    • 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.
