Every breath in Ghana\u2019s cities now carries a silent threat. According to experts, thousands of vehicles are moving without catalytic converters \u2014 a small but essential device that filters dangerous gases before they reach the air we all breathe. <\/p>\n

Many drivers remove it for what they mistakenly believe will deliver \u201cmore speed\u201d or \u201ccheaper fuel.\u201d But many mechanics are also stealing them from unsuspecting customers to strip and sell the precious metals they are made from.<\/p>\n

Air quality experts warn this has come at a high price for drivers and Ghanaians as a whole: polluted air, sick traders, drivers and children, rising hospital costs, and an environment that keeps getting worse.<\/p>\n

A City Waking Up to Dirty Haze<\/strong><\/p>\n

Kumasi wakes up early. Markets open, traffic builds, and the streets come alive. But behind the noise hangs something more dangerous \u2014 a thick layer of fumes floating quietly in the air. Everyone in the city breathes it, whether they know it or not.<\/p>\n

At the heart of the city\u2019s automobile industry, Suame Magazine, the biggest auto repair workshop, the problem is no secret.<\/p>\n

\"Experts<\/figure>\n

Exhaust welder Mark Opoku sees the pattern every week. He says the problem has worsened over the years. Almost weekly, drivers ask him to remove their catalytic converters.<\/p>\n

\u201cCustomers complain all the time,\u201d he says, brushing metal dust from his hands. \u201cThey say the converter slows the car or costs too much to repair. When it spoils, they refuse to replace it.\u201d<\/p>\n

\"Experts<\/figure>\n

For Mark, the trend is clear: \u201cIf you take 100 cars that originally came with converters, maybe only 20 still have theirs working. The rest? Removed \u2014 especially taxis.\u201d<\/p>\n

Some drivers, he adds, simply don\u2019t believe the converter helps the vehicle.<\/p>\n

\"Experts<\/figure>\n

The Small Part Causing Big Problems<\/strong><\/p>\n

A catalytic converter is a small device on a vehicle\u2019s exhaust pipe that helps clean the air. When a vehicle burns fuel, it creates dangerous gases that can harm people\u2019s lungs and the environment. The catalytic converter uses special metals to change those toxic gases into safer ones before they come out of the tailpipe.<\/p>\n

Many drivers in Ghana believe a catalytic converter is \u201cbad\u201d for their car, but experts say most of these ideas come from misinformation. When an old or poorly serviced engine starts burning too much fuel, it can clog the converter and make the car feel slow. Converters also expire after 10 years. <\/p>\n

\"Experts<\/figure>\n

Instead of fixing the real engine problem, some mechanics tell drivers to remove the converter entirely, which makes people think the device was the cause. The high cost of replacing it also adds to the belief that it is a troublemaker rather than a safety tool.<\/p>\n

Some mechanics have another incentive to remove the converters:<\/p>\n

Rhodium in a catalytic converter<\/em><\/p>\n

\u201cPeople steal catalytic converters or remove them to sell,\u201d says Dr Godwin Kafui Ayetor, senior automobile engineering lecturer at KNUST University in Kumasi, explaining they contain precious metals such as platinum, palladium, and rhodium \u2014 highly valuable on the scrap market. \u201cThis is not only in Ghana. In the US, thousands are stolen every year.\u201d<\/p>\n

Often, the theft happens before the vehicle reaches the shores of Ghana.<\/p>\n

\"Experts<\/figure>\n

A United Nation Environmental Programme report shows that many used vehicles exported to Africa arrive with missing or compromised converters \u2013 some are stolen or simply expired. A minimum of 23 million used vehicles were exported between 2015-2022 to low and middle-income countries. One in three of those exports came to Africa.<\/p>\n

Here at Suame magazine, mechanics tell customers that converters can actually reduce fuel waste and keep engines efficient saving them money long term.<\/p>\n

\u201cCatalytic converters must be expensive because of the important job they do,\u201d says Seidu Salifu, another mechanic.\u00a0 \u201cThey help the engine run well and reduce dangerous smoke. If a part does a big job, it will cost more.\u201d<\/p>\n

Dr Ayetor says removing converters actually makes the car more expensive to operate. The engine\u2019s oxygen (lambda) sensors depend on the converter to burn fuel properly. Without it, the engine enters \u201cdefault mode\u201d and wastes fuel.<\/p>\n

\u201cThat is why many drivers complain about high fuel consumption,\u201d he adds.<\/p>\n

Missing Converters Add to Ghana\u2019s Dangerous Levels of Air Pollution<\/strong><\/p>\n

\"Experts<\/figure>\n

What many drivers also don\u2019t know is that a catalytic converter also protects people, not just engines. It cleans the toxic fumes that come out of a vehicle\u2019s exhaust pipe, reducing dangerous gases that make people sick. When converters are removed, vehicles release far more pollution\u2014right into the homes, markets, and schools.<\/p>\n

Combatting dirty air is rapidly becoming an urgent priority in Ghana as air pollution levels climb each year. The most recent World Health Organization study found that 32,000 Ghanaians are dying prematurely because of air pollution. The biggest contributor in Ghana by far is transport.<\/p>\n

Experts say millions more are being sickened by illnesses such as asthma, lung, respiratory and heart disease caused or exacerbated by air pollution. Children, older adults, and pregnant women are especially vulnerable.<\/p>\n

\"Experts<\/figure>\n

\u201cIt is very worrying and many people are getting sick unnecessarily,\u201d says Dr Sandra Kwarteng Owusu, pulmonologist at the KNUST School of Medicine.<\/p>\n

Traders, Pedestrians and Commuters In the Firing Line of Dirty Air<\/strong><\/p>\n

At nearby Kumasi Central Market, the health impacts of the toxic air spewing from vehicles are clear. Fumes settle on traders\u2019 stalls from morning to evening. Traders here know the danger, but they feel powerless.<\/p>\n

\u201cI\u2019ve heard these fumes can cause cancer, and I believe it,\u201d says Selina Addai, a second-hand clothing seller who spoke in Twi. \u201cI know people who became sick after breathing fumes for years.\u201d<\/p>\n

\"Experts<\/figure>\n

\u00a0\u201cMost vehicles that pass release heavy smoke,\u201d says Ophelia Asare. Another trader also said, \u201cWe cough every day. I go for regular checkups because of the fumes.\u201d<\/p>\n

Schoolchildren are also on the frontlines. Schools are often located near heavy traffic zones. A team in the KNUST Department of Meteorology and Climate Science monitored pollution in 14 schools across Kumasi from 2022 to 2024 and found worrying results.<\/p>\n

\u201cMost schools had air pollution above safe levels,\u201d says study lead Dr Edmund Yamba. \u201cSchools near busy roads were the worst. Without catalytic converters, the situation will worsen.\u201d<\/p>\n

With Increasing Knowledge,<\/strong> Vehicle Owners Are Seeing the<\/strong> Benefits of Converters<\/strong><\/p>\n

Musah Abubakari is one driver who saw firsthand the need for a catalytic converter. His car began burning fuel excessively, making unusual noises, and releasing thick smoke whenever he started the engine.<\/p>\n

\"Experts<\/figure>\n

\u00a0\u201cI realised the car was consuming fuel, it was making unusual sounds, and plenty of fumes were coming out,\u201d he says. \u201cWhen I checked, I saw the converter had been removed.\u201d<\/p>\n

The thick smoke was not only polluting Kumasi\u2019s air \u2014 it was draining his wallet. Musah searched online, bought a new converter, and the problem disappeared.<\/p>\n

\u201cThe engine became calm. The smoke stopped, and my fuel use returned to normal,\u201d he says. \u201cI advise drivers to fix their converters. It helps the car and the environment.\u201d<\/p>\n

Ghana\u2019s Environmental Protection Authority has carried out many actions over the past decade to improve air quality. It has enforced environmental assessment regulations that require industries to adopt preventive measures, install pollution control systems, and monitor emissions and implemented the Ghana Online Continuous Emission Monitoring System, which strengthens real-time monitoring and enables quick action when emission levels rise.<\/p>\n

In an interview, Selina Amoah, head of the Environmental Quality Unit at the Authority, said the 2025 Environmental Protection Act provides a stronger legal framework to control emissions from all pollution sources, including vehicles.<\/p>\n

Though the Act does not mention catalytic converters specifically, it requires all vehicles to undergo emission testing at designated centres. Vehicles that pass the test will receive an Emission Compliance Certificate to show they are roadworthy. Experts say it is impossible to pass this test without a converter.<\/p>\n

\u201cCurrently, we have about 70 emission testing centres, and any vehicle that does not pass the test is not worthy to be on the road,\u201d she said. There is also a ban on imports of vehicles older than 10 years.<\/p>\n

Experts agree that Ghana now has good laws requiring vehicles to meet emission standards, but they say they have yet to be enforced.<\/p>\n

\"Experts<\/figure>\n

Dr Ayetor says the country must stop importing vehicles without converters, enforce emission inspections, adopt designs that place converters closer to the engine, and tag converters to reduce theft. \u201cIf there is no converter, the car should fail the test,\u201d he says.<\/p>\n

Experts say raising public awareness through education campaigns would be another important strategy. Richard Boadi, Ashanti Region Environmental Protection Agency Deputy Director, says the Authority will start awareness creation about the new regulation and enforce it. He agrees that though progress is slow, strict rules and public cooperation can help.<\/p>\n

\"Experts<\/figure>\n

\u201cThose who use catalytic converters can testify that emissions are reduced,\u201d he says. \u201cWe advise people to use them. It is for the safety of everyone.\u201d<\/p>\n

Mechanic Mark Opoku says making the process cheaper will be essential.<\/p>\n

\u201cA new catalytic converter can cost about GHS1,000,\u201d he says. \u201cMost drivers will not pay for that. Government should subsidize or reduce taxes. Otherwise, people will keep removing them.\u201d<\/p>\n

\"Experts<\/figure>\n

In the meantime experts urge drivers to check their catalytic converter and replace or install as soon as they can. And until then, to wear nose masks whenever they\u2019re near the vehicle or in traffic.<\/p>\n
