The Nigerian government has since 2016 been making repeated promises to end the importation of dirty fuels. In June 2016, members of the Economic Community of West African States convened for a two-day workshop in Abuja. The sole aim was to chart ways to transit into using low sulphur fuels in their respective countries. At the end of the event, Nigeria, Benin, Togo, Ghana and Côte D’Ivoire agreed to ban the importation of Europe’s dirty fuels, thus limiting sulphur in fuels from 3000ppm to 50ppm. The United Nations Environment Programme (UNEP) said the move would help to drastically reduce vehicle emissions and help over 250 million people to breathe safer and cleaner air.
