What Are EU Stage V Emissions Regulations?
The EU emissions regulations were introduced in 1997 with the purpose of reducing the level of harmful diesel engine emissions for nonroad mobile applications. This legislation introduced limitations on emissions of particulate matter (PM) and nitrogen oxides (NOx), carbon monoxide and hydrocarbons. Since then, a range of stages have been introduced with varying degrees of restrictions.
The latest regulations, EU Stage V, were introduced in 2019 and aim to further reduce emissions by setting stricter limits on particulate matter and extending the power ranges to which these regulations apply. The new regulations will now also cover the smallest (<19kW) and largest (>560 kW) engines, setting a minimum stringency over the entire power range.
