Non-road Mobile Machinery

Since 1997 Community legislation has required new diesel engines to meet certain environmental standards for air pollutants before they are placed on the market. 

Engines in non-road mobile machinery contribute to emissions of air pollutants.  Diesel engines in excavators, bulldozers, front loaders, back loaders, compressors etc. emit nitrogen oxides (NOx) and particulate matter. Emissions from these engines are regulated before they are placed on the market by Directive 97/68/EC

Also emissions from small spark ignition (petrol) engines are contributing to emissions - especially emissions of hydrocarbons (HC). One hour use of a normal chainsaw equipped with a two-stroke engine emits as much hydrocarbons as driving a modern passenger car for 2000 km. Emissions from these engines are regulated by Directive 2002/88.
