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 six directives: the "mother" Directive 97/68/EC, the amendments Directive 2002/88/EC, Directive 2004/26/EC, Directive 2006/105/EC, Directive 2011/88/EU and the last amendment Directive 2012/46/EU
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.
Proposal for a Regulation of the European Parliament and of the Council on requirements relating to emission limits and type-approval for internal combustion engines for non-road mobile machinery - 25.09.2014
The European Commission has proposed measures which will cut emissions of major air pollutants from engines in non-road mobile machinery and cut the complexity of the legal framework for the sector. The proposal provides for more stringent emission limit values for internal combustion engines installed in non-road mobile machinery (NRMM). At the same time, it sets out harmonised rules for placing those engines on the EU market. The new Regulation will replace a patchwork of 28 national laws on this matter. It will also repeal an extremely complex directive comprising 15 Annexes and amended 8 times since it was adopted in 1997.
