The European Stage V emission standard - you've heard all about it. But what is it exactly? Who is it interesting for? And why, actually? In case you can't see the wood for the trees: Boels has put together 5 facts and 5 myths for you:


  1. STAGE V IS MANDATORY Yes. Only for engine manufacturers in the NRMM sector (non-road mobile machinery). As of 1 January 2020, they are required to build cleaner engines that emit less harmful substances.

  2.  YOU CAN ALSO STILL USE OLD ENGINES Yes. Manufacturers may continue producing transitional engines (up to 56 kW and from 130 kW) until 30 June 2020 and continue to sell them until 31 December 2020. The same applies in 2021 for machines from 56 to 130 kW.

  3. STAGE V IS EXPENSIVE Yes. Buying machines with Stage V engines is generally more expensive and they consume slightly more diesel. In addition, virtually all of the machines require the addition of AdBlue to reduce nitrogen oxide (NOx) emissions. AdBlue is a mixture of demineralised water and urea. It is injected into the exhaust gases, converting most of the NOx into nitrogen and water vapour. Generators and compressors in particular consume a lot of AdBlue. 

  4. STAGE V IS THE LAST STEP Yes. The stricter environmental requirements for diesel engines have been gradually phased in since 1996, and Stage V is the last step. However, development of alternative fuels and machines that cause even less pollution is well underway! Think, for example, of electric equipment (battery-powered) and hydrogen-powered vehicles.

  5. CLIENTS CAN REQUIRE USE OF STAGE V Yes. Clients can include a provision in the project requirements or in tenders that requires lower-emission construction. Stage V could then provide a solution.



    1. STAGE V IS MANDATORY FOR EVERYONE No. Stage V is not mandatory for end users, who are also allowed to use machines without Stage V engines. Construction equipment manufacturers are still permitted to install older engines. Within a few years, the older machines will be naturally phased out and at that point everyone will only be using Stage V.

    2. DIESEL ENGINES STILL CAUSE POLLUTION Yes and no. The emissions are minimal, but not at zero. Over the past 20 years, however, emissions have been drastically reduced. When Stage I was applied in 1999, the standard for particulate matter was 0.54 g/kWh. That is now at 0.015 g/kWh, representing a staggering 97% reduction!  NOx emissions have decreased by 96%, from 9.2 g/kWh to 0.4 g/kWh.  

    3. STAGE V WILL NOT BE IMPLEMENTED DUE TO CORONAVIRUS No. The implementation of Stage V will certainly continue, but the European Parliament agreed on a proposal from the NRMM sector last week to extend the deadlines by one year for engines up to 56 kW and from 130 kW. The sector strongly maintained the need for this extension as many 'old' stock engines would otherwise no longer be able to be used or sold due to the corona crisis. This would not positively contribute to the sustainability objectives.

    4. STAGE V IS THE SAME AS EURO 6 No. Euro 6 is the emission standard for road transport. Stage V is the European standard for off-road traffic (NRMM), i.e. construction equipment and generators as well as (inland) vessels. You also have TIER (Transcript Individual Engine Regulations), the standard used in the US. TIER 4 Final is comparable to Stage V.

    5. ELECTRIC IS BETTER THAN STAGE V Yes and no. Electric engines have zero direct emissions and, if they are charged with green electricity, they are more environmentally friendly than Stage V diesel engines. However, not every machine has an electric version, meaning that a Stage V diesel engine can still be the cleanest solution.



    As previously mentioned, buying new machines with Stage V engines can be a pricey endeavour. In other words, making a Stage V purchase is not always an option. However, hiring one is. Boels has an extensive fleet equipped with Stage V diesel engines. Some of our most commonly requested products are listed below:

    • Articulated boom lifts: 16 metre (product code 18022) or 26 metre (18041). These boom lifts have an extremely versatile range and high manoeuvrability. This makes them particularly well-suited for work in warehouses and factories, for example. You can also use an articulated boom lift outdoors to access areas that are inaccessible with a scissor lift or scaffolding, or are otherwise hard to reach. They are self-propelled, four-wheel drive and equipped with JIB for easy positioning.
    • Telescopic crawler aerial work platform: 14 metre (18011). Thanks to the low ground pressure, this boom lift can be used in the muddiest conditions. 
    • Compaction rollers: 7 tonne (13437) and 12.5 tonne (13445) and Sheep foot rollers, 1.5 tonne (13411), 7 tonne (13446) and 13 tonne (12432). Suitable for compacting and levelling large surfaces for constructions on land, roads and water such as foundations for roads, sites, etc. The 13446 and 12432 are also extremely suitable for steep inclines. 
    • Vibrating roller: 0.7 tonne (12401) and tandem rollers: 1.5 tonne (13442), 2.4 tonne (13443) and 2.6 tonne (12470). For asphalting and compacting work such as new constructions and maintenance of roads, sports grounds, car parks and playgrounds.
