UK, France and Germany lobbied for flawed car emissions tests, documents reveal
The UK, France and Germany have been accused of hypocrisy for
lobbying behind the scenes to keep outmoded car tests for carbon
emissions, but later publicly calling for a European investigation into Volkswagen’s rigging of car air pollution tests.
Leaked documents seen by the Guardian show the three countries
lobbied the European commission to keep loopholes in car tests that
would increase real world carbon dioxide emissions by 14% above those
claimed.
Just four months before the VW emissions scandal broke, the EU’s
three biggest nations mounted a push to carry over loopholes from a test
devised in 1970 – known as the NEDC – to the World Light Vehicles Test
Procedure (WLTP), which is due to replace it in 2017.
“It is unacceptable that governments which rightly demand an
EU inquiry into the VW’s rigging of air pollution tests are
simultaneously lobbying behind the scenes to continue the rigging of CO2
emissions tests,” said Greg Archer, clean vehicles manager at the
respected green thinktank, Transport and Environment (T&E). “CO2
regulations should not be weakened by the backdoor through test
manipulations.”
Vehicle emissions are responsible for 12% of Europe’s carbon emissions and by 2021, all new cars must meet an EU emissions limit of 95 grams of CO2 per km, putting accurate measurements of real emissions at a premium.
The loopholes would not only raise real world CO2 emissions from new
cars to 110g CO2 per km – well above the EU limit – but increase fuel
bills for drivers by €140 per year according T&E.
Huw Irranca-Davies, Labour MP and chair of an influential select
committee of MPs, the environmental audit committee, said: “Given that
the UK is struggling to bring down carbon emissions and other harmful
pollutants from road vehicles it is extremely worrying that the UK
government appears to be trying to water down the EU’s proposed new road
testing regime.

“As
well as cutting CO2 emissions, improving the efficiency of vehicles can
save lives by reducing the illegal levels of air pollution in UK
cities, so the Department for Transport should be making these tests
more rigorous not less.”
The WLTP test was supposed to remove loopholes that had allowed a gap
between real world CO2 emissions and test cycle ones to develop, which EU consultants have estimated at up to 20%.
But the UK lobbied for car makers to be allowed to exploit
flexibilities such as externally charging their batteries to full before
testing. The Department for Transport also argued that the best
available technologies should be shunned in favour of outdated ‘inertia
classes’, which involve manually adding 100 kilo weights to the car to
see what effect greater weight on the amount of CO2 the car pumps out. Research by the International Council on Clean Transportation
has found that car manufacturers often game these tests by optimising
test car performances at one pound below the desired inertia class. Germany
went further than the UK, calling for the tests to be conducted on
sloping downhill tracks, and for allowing manufacturers to declare a
final CO2 value 4% lower than the one measured. France supported all the
proposed loopholes, bar the 4% lower CO2 value.
Together, these flexibilities would allow some 14% more CO2 to be
emitted than EU regulations permit, according to an analysis by T&E.
CO2 emissions contribute to climate change, while the nitrogen oxides
(NOx) that VW rigged tests for are primarily a cause of local air
pollution.
In a letter to the European commission on 29 May, Bob Moran, the
Department for Transport’s head of regulation and R&D argued that a
‘correlation tool’ between the old and new tests should include the old
procedures for inertia classes and battery recharges.
“It appears to be a common position under NEDC test conditions that
manufacturers will (request to) recharge the battery during the soak
period, or (request to) replace a partially depleted battery with a
fully charged one at the start of the test proper,” he wrote. “We
believe this commonly used approach should be reflected in the
correlation tool.” France
backed this position for technical reasons, arguing that it provided
“repeatable information”. But a fully-charged battery also prevents a
car’s alternator from kicking in and releasing carbon emissions during
tests, as would happen in real world driving situations.
The head of IG Metall Trade Union, Berthold Huber, says the VW CEO’s resignation was received with the greatest respect
In a sign of growing anger at the VW emissions-rigging scandal, which saw Martin Winterkorn resign on Wednesday,
the European parliament’s environment committee voted earlier today for
real world air pollutant emissions tests to begin no later than 2017.
The panel of MEPs also demanded that no loopholes or deviations be allowed for pollution limits.
“For too long European car makers have been ducking the EU’s rules to
enable them to keep their highly polluting cars on the road,” said
Keith Taylor, the Green MEP for south-east England. “The huge scandal
with Volkswagen on car pollution rules must focus the minds of EU
politicians and the British government. Air pollution kills tens of
thousands in the UK every year. With the added unchecked emissions from
Volkswagen cars, I worry about how much worse the situation actually
is”.
