Exhaust emissions from diesel engines used in road transport and in non-road mobile machinery are subject to stringent approval requirements. Manufacturers must evidence that vehicles or engines comply with the latest environmental standards before being placed on the market.

The latest standards for road vehicles include assessment of emissions over a wide range of driving conditions during on-road testing. This has resulted in significant reductions in the real-world emissions of new diesel vehicles.
