In-line with the government commitment to reduce emission to protect human health, the Federal Ministry of Environment in collaboration with Ministry of Trade and Investment/Standard Organization of Nigeria (SON), and in due consultations with relevant stakeholders, have successfully reviewed Standards of sulphur content in diesel and Petro- products. The specified level of sulphur that would henceforth be acceptable in petroleum fuels used in the country is as follows: From July 1, 2017, diesel should have maximum sulphur levels of 50 parts per million (ppm) (Reference NIS 948:2017); from July 1, 2017, petrol should have maximum Sulphur levels of 150 ppm (Reference NIS 116:2017); and from July 1, 2017, Household Kerosine (HHK) should have maximum Sulphur levels of 150 ppm (Reference NIS 949:2017).
Nigeria also facilitated an ECOWAS Agreement on Sulphur content in diesel and Petro- products.
Petroleum products that have high sulphur contents levels produce high emission levels in automotive engines. Such vehicular emissions contain high level of toxic pollutants such as benzenes and particulates that have negative impacts on human health and on the environment. Modern vehicles require fuels that meet high quality standards for a more efficient operation of their engines. Nigeria’s current import standards are 3,000 ppm on diesel and 1,000 ppm on gasoline.
