Emissions from non-road mobile machinery
Non-Road Mobile Machinery (NRMM) covers a large variety of engine installations in machines used for purposes other then for passenger or goods transport.
Diesel and spark emission engines installed in these NRMM such as excavators, bulldozers, front loaders, back loaders, compressors contribute greatly to air pollution by emitting carbon oxide (CO), hydrocarbons (HC), nitrogen oxides (NOx) and particulate matters. In line with the EU environmental policy it is the objective to progressively reduce the emissions and to phase out polluting equipment.
Emissions from these engines are regulated before they are placed on the market by four directives: the Directive 97/68/EC 
, amended by the Directive 2002/88/EC , by the Directive 2004/26/EC and by the Directive 2006/105/EC
For the various types of NRMM, the Directive stipulates the maximum permitted exhaust emissions as a function of the power of the relevant engine. Moreover the Directive includes a series of emission limit stages of increasing stringency with corresponding compliance dates. Manufacturers must ensure that new engines comply with these limits in order that they can be placed on the market.
