Sulphur in petroleum fuels results in vehicle exhaust emissions that have negative health and environmental impacts. Harmful emission reducing technologies in vehicles also require low Sulphur fuels to be effective.
Hence, the Standards Organisation of Nigeria, after due consultations with relevant stakeholders, has therefore reduced the maximum allowed levels of Sulphur in Petroleum fuels in Nigeria as follows:
- From 1st July 2017, Diesel fuel (AGO) should have maximum Sulphur levels of 50 parts per million (ppm) (Reference NIS 948:2017).
- From 1st July 2017, Petroleum motor spirit (Petrol) should have maximum Sulphur levels of 150 ppm (Reference NIS 116:2017)
- From 1st July 2017, Household Kerosine (HHK) should have maximum Sulphur levels of 150 ppm (Reference NIS 949:2017).
According to a statement by the Director General of National Automotive Design and Development Council, Engr. Aminu Jalal, “Petroleum fuels that have high sulphur levels generate directly high emission levels in automotive engines.
Such vehicle emissions contain high level of toxic pollutants such as benzenes and particulates that have negative impacts on human health and on the environment”.
