Welcome to NRMM System

The Air Pollution Control (Non-road Mobile Machinery) (Emission) Regulation took effect on 1 June 2015. From 1 September 2015 all regulated machines sold or leased for use in Hong Kong must be approved or exempted with a label issued by EPD. Existing NRMMs which were in Hong Kong on or before 30 November 2015 could exempt from complying with the emission requirements. Starting from 1 December 2015 only approved or exempted NRMMs with a proper label are allowed to be used in specified activities and locations including construction sites, container terminals and back up facilities, restricted areas of the airport, designated waste disposal facilities and specified processes.

The Regulation was amended in 2018 to tighten statutory emission standards of the following types of newly approved non-road vehicles with effect from 1 January 2019:

(1) newly approved non-road goods vehicles, petrol private cars, buses with design weight of more than 9 tonnes and light buses with design weight not exceeding 3.5 tonnes are required to comply with Euro VI emission standards; and

(2) newly approved non-road diesel private cars are required to comply with California LEV III emission standards.

Emission standards for other non-road vehicle classes, including buses with design weight not exceeding 9 tonnes, light buses with design weight of more than 3.5 tonnes and special purpose vehicles remain unchanged.
