The EN 590 had been introduced along with the European emission standards.With each of its revisions the EN 590 had been adapted to lower the sulphur content of diesel fuel – since 2007 this is called ultra-low-sulphur diesel as the former function of sulphur as a lubricant is absent (and needs to be replaced by additives).
Cold filter plugging point (CFPP) is the lowest temperature, expressed in degrees Celsius (°C), at which a given volume of diesel type of fuel still passes through a standardized filtration device in a specified time when cooled under certain conditions.
In 1993 the European Union began mandating the reduction of diesel sulfur content and implementing modern ULSD specifications in 1999. [ 3 ] [ 4 ] The United States started phasing in ULSD requirements for highway vehicles in 2006, with implementation for off-highway applications, such as locomotive and marine fuel, beginning in 2007.
In the 1990s specifications allowed a content of 2000 ppm max of sulfur, reduced to a limit of 350 ppm by the beginning of the 21st century with the introduction of Euro 3 specifications. The limit was lowered with the introduction of Euro 4 by 2006 to 50 ppm (ULSD, Ultra Low Sulfur Diesel). The standard for diesel fuel in force in Europe as of ...

[31] Circle-K provider delivers winter diesel with a CFFP of –32 °C the whole year. [31] The OKQ8 company offers two types depending on the region with currently two areas separated by the Dalälven river at 60° north ...
Various governmental agencies involved with environmental protection and with occupational safety and health have promulgated regulations limiting the allowable concentrations of gaseous pollutants in the ambient air or in emissions to the ambient air.
Neste MY Renewable Diesel (formerly NExBTL) is a vegetable oil refining fuel production process commercialized by the Finnish oil and refining company Neste.Whether as an admixture or in its pure form, the fuel is able to supplement or partially replace conventional diesel without problems.
In the European Union, emissions of nitrogen oxides (NO x), total hydrocarbon (THC), non-methane hydrocarbons (NMHC), carbon monoxide (CO) and particulate matter (PM) are regulated for most vehicle types, including cars, trucks (lorries), locomotives, tractors and similar machinery, barges, but excluding seagoing ships and aeroplanes.
