A new test protocol for non-road mobile machinery (NRMM), developed by scientists at the JRC Institute for Environment and Sustainability (IES) in cooperation with experts from the United States and Japan, has been adopted as a global technical regulation by the United Nation’s Economic Commission for Europe (UN-ECE) Working Party on Pollution and Energy (GRPE).
Internationally harmonized test protocols for emission control contribute to reducing pressures on the environment and to more efficient use of energy. They also facilitate innovation and competitiveness by allowing manufacturers to develop engine models that can meet internationally consistent emissions regulations.
