Low Sulphur Fuel– Environmental, Legislative and Economical Aspects

The clean fuels have a critical role in preservation of clean air. Understanding of urban air pollution and the role of vehicle exhaust are one of the prerequisites for environmental sustainability. Sulphur in gasoline and diesel contributes to overall air pollution that negatively affects the health of population and the global environment. Concerns related to the health effects of air pollution, especially in urban areas, have been a primary driving force in settling sulphur standards. Regulating the sulphur content in fuels has economic and social benefits for society, as well as cost and competitiveness implications for the refining industry. Establishing limits for sulphur in gasoline and diesel fuel is one aspect of a larger program for clean air that has involved many federal, provincial and municipal actions worldwide and a broad consultative effort. The outcome of European efforts to stop further air pollution was a decision to regulate sulphur to below 50 ppm by the year 2005 and even less by the introduction of zero sulphur fuel with sulphur content below 10 ppm. Zero sulphur fuel with less than 10 ppm clearly reduces the contribution of road traffic to sulphur emissions. Moreover, zero sulphur fuel not only has a beneficial effect on particulate, HC, NOx and CO emissions but also indirectly reduces the CO2 emissions of road traffic compared to use of current commercially available fuels. Promoting sustainable urban transport through usage of low sulphur fuel is one part in achieving global environmental sustainability and therefore all parties involved have to give a maximum effort in attaining placed goals.
