A three-year investigation published by Switzerland-based environmental and economic group Public Eye did not accuse oil companies of breaking any laws.
But it charged several firms with using an “illegitimate strategy” to boost profits, hawking so-called “African quality” fuels that have had devastating health and environmental impacts across many sub-Saharan states.
In a 160-page report based on research in eight African countries, Public Eye found fuels sold at the pump which contained high levels of toxins, notably sulphur.
Such toxic blends would be illegal to sell in Europe, which caps sulphur rates in fuel at 10 parts per million, Public Eye said.
In Africa, sulphur limits are on average 200 times higher.
“By selling such fuels at the pump in Africa, the traders increase outdoor air pollution, causing respiratory disease and premature death,” said the report from Public Eye, a group previously known as the Bern Declaration and founded in 1968.
Among the key culprits, Public Eye named Swiss traders Vitol and Trafigura as well as the multi-national energy group Oryx, which specialises in the African market.
In a statement sent to AFP, Vitol called the report “inaccurate and misinformed,” stressing that African governments were responsible for setting their own fuel standards.
Oryx made the same case, noting in a statement that it sells fuel products “that strictly comply with the national legislation of each client country.”
Call to act
Public Eye tested fuel sold in Angola, Benin, Congo-Brazzaville, Ghana, Ivory Coast, Mali, Senegal and Zambia.
While sub-Saharan Africa includes major oil producers like Angola and Nigeria, limited refining capacity on the continent means that most African oil is sold as crude on the international market.
States then import fuel products refined abroad, often from European traders.
These transactions often involve regional brokers in Africa, who are sometimes responsible for mixing the fuel.
Public eye called on African governments “to set stringent fuel quality standards” in line with European levels, arguing that was the most effective way to crack down on toxic blends.
Fears that banning low-quality blends will raise costs for consumers are misguided, the report said.
It noted that measures in East Africa to limit sulphur continent had “no impact on prices at the pump.”
Importing better fuel would also lower healthcare expenses and reduce vehicle maintenance costs in the long run, Public Eye argued.
With many of the toxic blends produced in Europe and the United States, Public Eye urged Western governments to ban the export of fuel products that do not meet their own domestic standards.
