REMA reports high vehicle emission failures across Rwanda

By The Inspirer.

More than one in five vehicles tested for gas emissions in Rwanda failed to meet the required environmental standards, according to the Rwanda Environment Management Authority (REMA).

Between August 31 and October 31, a total of 6,164 vehicles were inspected at the country’s four automobile inspection centers in Remera, Musanze, Nyamagabe, and Huye. REMA reported that 22.6 percent of those vehicles did not pass the emission tests.

According to the agency, vehicle exhaust fumes remain one of the leading sources of air pollution in the country. For diesel engines, inspectors measure the opacity of exhaust fumes, while for petrol-powered vehicles, they test hydrocarbon and carbon monoxide levels. Any vehicle that exceeds the emission limits automatically fails the inspection.

Speaking during a demonstration of gas emission testing at the Remera Automobile Inspection Center on Friday, November 1, Environment Minister Dr. Bernadette Arakwiye said the ongoing inspection campaign is exposing the poor mechanical condition of many vehicles operating on Rwandan roads.

“We have been testing cars for a while, and the key lesson we are learning is that many vehicles are simply not in good shape,” Dr. Arakwiye said.

The minister emphasized that emission testing is not only about reducing pollution but also about helping vehicle owners identify maintenance needs and prevent mechanical failures.

She noted that several vehicles that had been granted a second chance after failing initial tests still showed little to no improvement.

Anokwaye further pointed out that older and poorly maintained vehicles have been the least compliant with emission standards.

She revealed that the government is planning to introduce stricter regulations to ensure that all vehicles, particularly those used for commercial purposes, undergo mandatory emission testing.

“For a vehicle to be allowed for commercial use, it must pass an emission test. This ensures that the transport system we rely on—especially for the young and elderly—is safe and sustainable,” she said.

The minister also urged vehicle owners to be proactive about maintenance and to work closely with certified garages to ensure that their vehicles meet the required standards.

“We are committed to improving air quality in our cities,” Anokwaye added. “Poor air quality affects everyone, and responsible vehicle maintenance is one of the key ways to address this.”

According to REMA, Rwanda continues to strengthen its pollution control measures as part of broader efforts to reduce greenhouse gas emissions and promote environmental sustainability.
