London's 'Low Emission Zone' for Non-Road Mobile Machinery
Non-Road Mobile Machinery (NRMM) is a broad category which includes mobile machines, and transportable industrial equipment or vehicles which are fitted with an internal combustion engine and not intended for transporting goods or passengers on roads.
NRMM, particularly from the construction sector, is a significant contributor to London’s air pollution. The NRMM Low Emission Zone uses the Mayor and London Borough’s planning powers to control emissions from NRMM used on construction sites.
In a similar way to the Ultra Low Emission Zone the NRMM Low Emission Zone requires that all engines with a power rating between 37 kW and 560 kW meet an emission standard based on the engine emission “stage”.
The standards that need to be met depend on where the construction site is:
The current standards are stage IIIB for construction machinery operating in the Central Activity Zone and Canary Wharf Areas and stage IIIA in the rest of London.
