5.3% of company cars and vans being operated by customers of FleetCheck only meet the Euro 4 emissions standard or older, according to a new analysis.

A further 18.2% of vehicles from the total sample of 85,792 also fall behind the latest Euro 6 legislation by only achieving Euro 5, figures released by the fleet software specialist show.

Peter Golding, managing director at FleetCheck, said: “We compiled these figures to illustrate the disparity that currently exists across fleets when it comes to emissions. While at one extreme, some are actively working to achieve zero emissions, at the other, we can see that almost a quarter of all the vehicles our customers operate are Euro 5 or older.

“Because there is a strong SME bias in our customer base and these businesses tend to hang on to cars and vans for longer than corporates, they are probably worse than the fleet parc as a whole. However, they remain an indication of how far the industry will have to travel to achieve the kind of low or zero-emissions performance we’d all like to see.”

Peter added that most of the oldest and most polluting vehicles in the analysis appeared to be diesel vans, many of which were operated on a spare or pool vehicle basis.

“It is not uncommon for smaller businesses to continue to operate vans until they become uneconomic to repair or too unreliable for everyday use. Even some of the latter will be kept in the yard as a spare van and used occasionally. However, there is a strong argument that these vehicles shouldn’t be on the road at all, given their poor emissions.”

Over the next few years, he added, there was a strong possibility that the introduction of Clean Air Zones would start to see more of these vehicles disappear from fleets.

“While CAZs have arguably got off to a slow start, it seems likely that at least some will ultimately move to the ULEZ model and operate a Euro 6 minimum for diesel vehicles. This is one of the factors that will start to see some of these older vans start to disappear.

“However, well ahead of that point, more could be done to persuade fleets to stop operating these vehicles. That might mean disincentives using measures such as Vehicle Excise Duty or it could mean incentives such as wider use of scrappage schemes.

“On a simpler level, the economics behind the ongoing operation of these older vans are often highly questionable, and getting this message across to businesses is also something that we perhaps should be communicating more widely as an industry.”
