REGULATIONS’ CORNER – Emissions from Construction Equipment Engines

Emissions from construction equipment engines are regulated in four stages of Directive 97/68/EC amended by Directive 2004/26/EC relating to engine emissions of non-road equipment in the EU. Stage II entered into force in 2004, stage IIIA in 2006. Stage IIIB is scheduled for 2011 and stage IV is schedules for 2014. Introduction dates and emission levels are aligned with US-based rules for non-road mobile machinery.

On 8 November 2011, the Council of the European Union (representing EU Member States) supported a decision already taken in October by the European Parliament, in favour of increased flexibility for the introduction of new engine emissions for mobile machinery.

The revised flexibility clause for construction equipment relates to exhaust emissions of non-road mobile machines (thus also construction equipment). It ensures that technical modifications required to fulfill emissions limits of stage IIIB can be introduced over a longer period of time. The European Parliament accepted the increase of flexibility to 37.5% and also the increase of the fixed quantities with a factor 2.5  as it was requested by the European Commission. This measure will lead to a smooth transition from the engine emission stage IIIA to IIIB but is only valid during the duration of stage IIIA with a maximum of 3 years.
