European national authorities “encouraged” car
manufacturers to produce diesel cars that polluted more than EU limits allowed
by insufficiently investigating emissions of cars on the road, a French
committee concluded in a report published Friday (29 July).
The report said market
surveillance of emissions of diesel vehicles, once sold, was “largely
insufficient”.
“The absence or lack of
transparency of surveillance testing and control by public authorities on
emissions of vehicles offered for sale in the European Union, constitutes
incitement to fraud and therefore must be absolutely corrected,” the committee
wrote.
The group was set up in
October 2015 by French environment minister Segolene Royal after the Volkswagen
emissions cheating scandal raised suspicions about other car manufacturers'
behaviour.
It included members from
the environment ministry, French MPs, research institutes, environmental and
consumer groups, but also representatives from industry.
At the committee's
request, France's car certification body carried out emissions tests on 86
vehicles. Just like previous exercises carried out by German and UK
authorities, it found that many diesel cars were emitting much higher
pollutants on the road than in the laboratory.
The committee concluded
that car manufacturers were “systematically” using defeat devices, which
switched off or turned down the emissions filter system under certain
conditions.
These are banned under
EU law, but an exception exists: if they are used to protect the engine.
The authors of the report said it seemed that in some
cases the exception was used too freely.
They asked carmakers to
explain why the emissions filter is sometimes switched off under normal driving
conditions, but complained about lack of cooperation from several carmakers.
“At this stage, the
committee has not demonstrated the use of illegal defeat devices, but can not rule
them out either,” the report noted.
The committee concluded
that car manufacturers designed their diesel cars to pass the test, but not to
stay under EU pollution limits in the real world.
“The impacts that this
approach generates on the emissions of harmful elements and the air quality
near roads seem to have been largely ignored” during the design phase, they
wrote.
The report also gave an
insight into where the cars were certified. The cars that were tested had
mostly been certified in western Europe. However, there appeared to be no
correlation to certain testing authorities compared to bad performances on the
road.
A Citroen C4 Picasso for
example emitted 4.1 times the EU limit when driving on the road. It was tested
and approved in France.
A BMW 116D emitted 6.2
times above the limit. It was tested for emissions in Ireland and received its
final approval to be sold on the market in Germany.
A Ford C-Max (6.1 times
above the limit) was tested for emissions in the UK, and approved in
Luxembourg.
The report was delayed
several times, and the timing of its publication after 10 months of work is
conspicuous.
Originally scheduled to
be published in June, the report was finally released on a Friday afternoon in
the middle of summer, with public attention diverted by the European holiday
season.
The UK and Germany,
which carried out similar tests and produced similar results, published their
reports in April.
