Call For Proposals: Nigeria Soot-free Bus CNG/Electric Bus Deployment Projects (US$ 240,000 – US$ 300,000)

This project responds to the request by the Federal Ministry of Environment of Nigeria to develop a national policy on soot-free buses and a national strategy and implementation plan for the deployment of compressed natural gas (CNG)/electric powered buses. This project will also support Nigeria’s shift to low-sulfur fuels and the implementation of EURO IV vehicle standard adopted by the Economic Community of West African States (ECOWAS) in 2020.

Reducing short-lived climate pollutant (SLCP) emissions from transportation is a priority for Nigeria. The country is currently planning its CNG/electric program and has the opportunity to adopt a strategy for deploying CNG/electric buses given the removal of the state fuel subsidy by the President in May 2023. CNG is recognized as an important transition fuel that will also provide substantial public health and climate change benefits.

This project will support implementation of the mitigation measures endorsed in Nigeria’s National Action Plan to Reduce Short-Lived Climate Pollutants. The plan aims to reduce 75 per cent of PM2.5 emissions by 2030. The 22 priority mitigation measures identified include the regulation and enforcement of vehicle emission standards and targeted adoption of CNG buses. The plan also endorses recommendations for the conversion of 25 per cent of all buses to CNG by 2030.

The strategy and implementation plan this project will develop should build on lessons learned from the city of Lagos where two electric buses have been piloted.

This work should also support harmonization with ECOWAS vehicle standards to regulate cleaner fuels and vehicles, ongoing CCAC projects on soot-free bus technologies in the region, and proposed solutions that align with targets in Nigeria’s National SLCP Action Plan and NDC.

More information on Nigeria’s involvement in the CCAC is available on their Partner Page.


This project will require close collaboration and engagement with:

  • The Federal Ministry of Transportation that is responsible for framing the policies related to transportation systems, especially public transport strategies in Nigeria
  • The Federal Ministry of Environment that supports the framework for integrated climate and clean air action plans and has initiated deliberations on clean fuels and CNG
  • The Federal Ministry of Petroleum Resources that directs petroleum resources and its activities in Nigeria

The Ministry of Works and Housing as primarily responsible for formulating and implementing the policies, programs, and projects of the Federal Government of Nigeria (FGN) with respect to Road Transport.

Relevant policies, strategies, projects, or programs include:


Applicants are encouraged to propose additional outputs as needed to ensure the expected project outcomes are achieved. Applicants can determine the scope of outputs if not specified. The project is expected to deliver at a minimum:

1. The Government of Nigeria endorses a national policy on soot-free bus technologies and EURO IV vehicle emissions standards by the end of the project or soon after.

2. The Federal Government integrates priority SLCP mitigation measures, targets, and/or co-benefits assessments related to the transport sector in the revised NDC and implementation plan by 2025. 

Indicator: Number of NDCs targeting SLCPs. 

Output 2.1: Recommendations for the inclusion of SLCP reduction priorities, targets, and co-benefits in Nigeria’s 2025 NDC.

3. The Federal Government of Nigeria endorses/adopts regulations aligned with the ECOWAS directive for EURO IV vehicle standards by the end of the project or soon after.

Indicator: Number of laws, regulations, or other policy mechanisms with SLCP targets or mitigation measures formally adopted, endorsed, and/or implemented.

Output 3.1: Recommended regulatory options for the introduction of cleaner fuels and vehicles adopted by the ECOWAS Commission

4. The Federal Government endorses a national strategy and implementation plan for deploying CNG/electric buses by the end of the project or soon after.

Indicator: Number of action plans, roadmaps, strategies, or other future plans with SLCP targets or mitigation measures formally adopted, endorsed and/or implemented.

Output 4.1: Strategy for introduction of CNG and electric buses nation-wide including:

  • Data collection and analysis from the e-bus pilots in Lagos, and from other cities to be defined in consultation with the government to inform policy design and implementation
  • Recommendations for nation-wide expansion including financing options
  • Analysis of available bus standards, the adequacy of infrastructure, energy production and sourcing, technology availability and transfer, flexible financing options, operational and regulatory considerations, institutional frameworks, fiscal incentives and financing model, existing policies, strategies, and programmes that would support a nation-wide CNG/electric programme

Output 4.1: An implementation plan for implementing the strategy

Output 4.2: National level dissemination and endorsement of the strategy and implementation plan
