West African Ministers Approve New Standards for Cleaner Fuels and Vehicles

In a major step toward improving air quality and tackling climate change, 15 West African countries have adopted a comprehensive set of regulations aimed at introducing cleaner fuels and vehicles across the region.

With a combined population of nearly 400 million, West Africa has one of the world’s fastest-growing vehicle fleets. However, most cars imported into the region are used vehicles, and weak import regulations coupled with low-quality fuels have led to rising air pollution levels. Urban residents, especially children walking to school and street vendors working along busy roads, face serious health risks from inhaling toxic exhaust fumes. In 2016, the World Health Organization (WHO) ranked Onitsha, Nigeria, as the world’s most polluted city in terms of harmful particulate matter (PM10).

At a meeting held on 6–7 February 2020 in Ouagadougou, Burkina Faso, environment and energy ministers from the Economic Community of West African States (ECOWAS) unanimously adopted new regional standards for fuels and vehicle emissions. The meeting was convened by the ECOWAS Commission, with support from the United Nations Environment Programme (UNEP) and other partners, following years of joint work to improve fuel and vehicle standards across West Africa.

Key Regulations Adopted

• Cleaner fuels: From 1 January 2021, all imported petrol and diesel must meet a maximum sulfur content of 50 parts per million (ppm)—a dramatic improvement for countries that still allow imports of diesel with up to 10,000 ppm
  Local refineries will have until 1 January 2025 to upgrade operations to meet the new standards and additional fuel quality parameters for benzene and manganese. Since 80% of the region’s fuel is imported, this measure is expected to significantly improve air quality.
• Vehicle standards: All new and used vehicles imported into the region must comply with at least the EURO 4/IV emissions standard starting 1 January 2021. The ministers also agreed to impose a 10-year age limit on imported used vehicles, with a recommended 5-year limit for light-duty cars.
• Fuel efficiency: A regional Fuel Economy Roadmap was adopted, aiming to halve fuel consumption from an average of 8 liters per 100 km today to 2 liters per 100 km by 2030, with an interim target of 5 liters per 100 km by 2025. The plan includes fiscal incentives to encourage low- and zero-emission vehicles, measures to promote electric mobility, and a new labeling system to inform consumers about vehicles’ fuel efficiency and CO₂ emissions.

The new regulations will be submitted to the ECOWAS Council of Ministers in June 2020 for formal approval. Once adopted, they will become legally binding and take effect no later than 1 January 2021.

“We are very pleased to see the results of a process that took several years,” said Jane Akumu, UNEP’s clean fuels and vehicles expert. “UNEP supported 11 of the 15 ECOWAS member countries with national projects and worked closely with the ECOWAS Commission to design these regulations.”

The initiative was supported by multiple partners and organizations, including the Climate and Clean Air Coalition, and UNEP-led global programs such as the Partnership for Clean Fuels and Vehicles, the Global Fuel Economy Initiative, and the Electric Mobility Programme.

Akumu emphasized that the work is far from over: “Several countries have already requested support to implement the new standards, develop national policies, and promote electric vehicles,” she said.
“Ultimately, adopting clean fuels and vehicles is not just an environmental or energy issue—it is a public health imperative for millions of people living in and around West Africa’s major cities.”
