Emissions regulations set by the EU and incorporated into UK law now require vehicle manufacturers to meet stringent emissions standards. In order to meet these standards, diesel vehicles often employ selective catalytic reduction (SCR) technology that involves injecting precise amounts of a liquid into the vehicle exhaust.
AdBlue is one of the most common of these systems. When the AdBlue solution combines with exhaust emissions, it produces harmless nitrogen and oxygen by breaking down the harmful mono-nitrogen oxides in diesel exhaust. This helps ensure the vehicle emissions comply with regulation and reduces air pollution.
Most modern diesel cars come fitted with SCR technology and AdBlue, which is stored in a separate reservoir near the fuel tank. Non-road mobile machinery used on construction sites are also often equipped with AdBlue. Where possible, sites should ensure they use AdBlue or an alternative SCR system to minimise their contribution to air pollution.
