Brazil - Develop a Vehicle Emissions Inspection Programme [BR-23-004]

by CCAC - 14 November, 2023


This project responds to the request of the Ministry of Environment and Climate Change of Brazil to develop a vehicle emissions inspection programme to monitor and reduce short-lived climate pollutants from vehicles (black carbon, PM 2.5 and sources of tropospheric ozone), and to prepare a project funding proposal for the implementation and evaluation of a vehicle inspection pilot project in one state.

The main source of pollution in Brazil’s metropolitan area is from emissions from road vehicles, including cars, buses, trucks and motorcycles. Short-lived climate pollutants from the transport sector are mainly black carbon (as small particulate matter 2.5) and tropospheric ozone (as result of emission of precursor pollutants such as methane, NOx, etc). Special attention will be given to heavy-duty diesel vehicles due to their significant contribution to air pollution. This includes monitoring compliance with exhaust smoke limits, as well as inspecting diesel particulate filters (DPFs) and ensuring proper maintenance of emissions control systems.

This project responds to the challenges that come with Brazil’s growing vehicular fleet in the metropolitan region. The State of São Paulo faces a particularly worrying situation because it holds about 40% of the country's automotive fleet. To monitor and reduce SLCPs from the transport sector it is necessary to regulate the emission standard of registered vehicles and to guarantee that the vehicles operate in good maintenance conditions. Brazil adopted PROCONVE 8 (P-8) standards, based on Euro VI, in 2018. P-8 standards entered into effect for new vehicle type approvals on January 2022, and for all new sales and registrations on January 2023; manufacturers are authorized to comply earlier with these standards. Therefore, a vehicle inspection programme is needed at the operational level to guarantee that the vehicle fleet operates in good condition, and to control and reduce black carbon emissions.

The results of this project are expected to include short-lived climate pollutants in Brazil’s vehicle inspection programme, and a project funding proposal for the implementation and evaluation of a vehicle inspection pilot project in one state. It will also include the formulation and adoption of a new regulation to control and monitor SLCP in the vehicle sector in line with the vehicle inspection programme.

More information on Brazil involvement in the CCAC is available on their Partner Page.

Who to involve

The Ministry of Environment and Climate Change is responsible for proposing, supporting, and implementing policies, plans and strategies related to air quality, climate change and waste management. Successful delivery of this project will require close coordination and engagement primarily with relevant ministries from across the government, including those with mandates in environment and climate change (including Environmental Protection Agency Ibama), transport, health, industry, metrology, regulation Agency, cities, infrastructure, finance, national planning, energy and the 26 State governments.

Expected results

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 Brazil includes short-lived climate pollutants (black carbon, PM 2.5 and sources of tropospheric ozone) in its vehicle inspection programme at project completion 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 1.1: Develop a vehicle inspection programme to monitor and reduce short-lived climate pollutants from vehicles. The programme will regulate the emission standard of registered vehicles and will guarantee that the vehicles operate in good maintenance conditions. It will include:

  • Emissions standards, definition of applicable vehicles, testing procedures, a system for compliance and enforcement as well as for monitoring and evaluation.
  • Institutional arrangements for implementation.

Output 1.2: Develop a short-lived climate pollutant mitigation assessment for the transport that should include: 

  • An assessment of mitigation scenarios to estimate the impact in terms of emission reductions from the vehicle inspection programme based on remote sensing techniques.
  • Gap assessment of the current laws, policies, and regulations regarding vehicle inspection.
  • Revision and benchmarking of national and international relevant and successful vehicle inspection programs and of their methodologies is conducted
  • Recommendations for improving the vehicle inspection process and overcoming barriers
  • Recommendation of incentives of compliance for vehicles that meet or exceed emission standards (eg. exemptions or reductions in registration fees, tax incentives, or access to preferential lanes)
  • Analysis of advanced technologies and methodologies to enhance the vehicle inspection process, including remote sensing techniques.
  • Technical and financial feasibility of implementing vehicle inspection using remote sensing techniques is carried out.
  • A plan with specific objectives, activities, and timelines for implementing vehicle inspection at the state level is developed

Output 1.3: Research and data collection to determine SLCPs emission factors. This data collection should be carried out with the vehicle moving on the roadway (real scenario) and not in a controlled environment or static situation. This output should include:

  • Improve the vehicle source inventory methodology.
  • Develop a national vehicle emissions inventory for mobile sources based on primary and secondary data.
  • Develop a specific system for the automatic calculations and dissemination of inventories of vehicle emissions.
  • Transfer knowledge and conduct trainings about the preparation of inventories of vehicle emissions, seeking to qualify public servers of the national and local level.
  • Establish emission standards that vehicles must meet to pass the inspection. These standards may be based on pollutant levels such as nitrogen oxides (NOx), carbon monoxide (CO), particulate matter (PM), or other relevant pollutants.

2. The Government of Brazil submits a project funding proposal to potential donors for the implementation and evaluation of a vehicle inspection pilot project in one State by the end of the project or soon after.

Indicator: Amount of external funding (“catalysed funding”) for SLCP actions.

Output 2.1: Prepare a project-funding proposal for the implementation and testing of a vehicle inspection pilot project in one state that builds on the analysis that will be conducted and on existing supporting policies, plans and strategies, and includes public awareness and education. 

3. The Government of Brazil has increased capacity to reduce SLCPs from heavy-duty vehicles and engines. 

Output 3.1: A national consultant for Brazil is recruited to support the project and related activities in cooperation with relevant government stakeholders.
