Use of construction machines and the associated NOx and CO2 emissions
report
Non-Road Mobile Machinery (NRMM) is the collective term used to refer to all machines with a combustion engine that do not come under the categories of road vehicles, sea-going vessels or aircraft. This group also includes diesel trains, inland vessels, generators and construction machines. Mobile machines (NRMM excluding ships, trains and aircraft) are responsible for a substantial proportion of the NO₂ air-quality problems. Estimates based on emission standards in the official laboratory test, as laid down in emissions legislation, and a generic distribution across the Netherlands indicate that around 10% of the NO₂ concentration in problem areas can be attributed to mobile machines. At present little is known about the emissions generated by and the use of construction machines in practice. It is therefore not known whether the emissions resulting from the normal operation of such machines in practice are adequately covered by the legislation requirements for these machines. There are no legal limits for real-world emissions of these machines. From the new Stage V legislation real-world emissions have to be monitored.
