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.
China has limited sulfur in diesel fuel to 150 ppm (equivalent to the Euro III standard). The limits of 10 ppm (equivalent to the Euro V standard), only apply in certain cities such as Beijing. [15] From 2014 to 2017, China will limit sulfur in diesel fuel to 50 ppm. After 2017, the sulfur content in diesel fuel will be limited to 10ppm. [16]

Air pollutant concentrations, as measured or as calculated by air pollution dispersion modeling, [1] must often be converted or corrected to be expressed as required by the regulations issued by various governmental agencies.
The Clean Fuels 2 standard, expected to begin in 2017, includes the reduction of sulphur to 10 ppm; the lowering of benzene from 5 percent to 1 percent of volume; the reduction of aromatics from 50 percent to 35 percent of volume; and the specification of olefins at 18 percent of volume.
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.
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.
