The requirements for reduction of truck emissions (in EU e.g. Euro 5 in 2009) are increasing on a worldwide scale. SCR-systems (SCR=selective catalytic reduction) are used in combination with the chemical synthetic product urea AUS 32 (AdBlue®) and thus lead to a reduction of NOx-emissions. In order to achieve a worldwide coverage of the product urea AUS 32 the VDA has registered the trademark “AdBlue” in all relevant car markets. By using the SCR-technology the truck industry can contribute worldwide to further reductions of emissions..
