The Portable Emission Measurement System (PEMS) aims to supplement
laboratory tests -- the flaws of which were laid bare by the VW
experience -- with more realistic testing on roads.
But Europeans shouldn't expect to be breathing much cleaner air in
the near future, experts and analysts say, because all the testing
regimens in the world won't solve the problem until the European
Union introduces much tougher pollution limits and finds a foolproof
way to enforce them.
VW's use of a banned "defeat device" has led to the scrutiny of a
system that has allowed nitrogen oxide (NOx) emissions to reach up
to seven times their European limits.
EU officials who spoke to Reuters on condition of anonymity said
that industry manipulation of the testing regime had been obvious
for years. The European Commission failed to stop it, they said,
because of the influence of the auto industry and because protecting
a pillar of the economy was for many a higher priority than the
environment.
"I was not in the least surprised when this came to light. I just
thought 'finally they have been caught' but I was amazed at their
stupidity in trying to cheat in the U.S.," said one of five EU
officials interviewed by Reuters.
The officials, who asked not to be named because they are not
authorized to speak to the press, said it was a mistake to leave
vehicle regulation primarily in the hands of the industry section of
the European Commission, rather than the environment department.
Although regulators did not know of anything clearly illegal going
on, they were aware loopholes were being exploited and chose to tune
out the problem, the officials said.
"There was no push from the hierarchy," said the EU official. "It
was failure by neglect."
A second official said: "Policy officers (on the lower levels)
develop a desire to do something meaningful ... higher up, they
don't want to rock the boat. The lower down the pecking order you
are, the closer you are to the facts."
Commission spokeswoman Lucia Caudet said the Commission had worked
for many years to improve regulation in consultation with all
relevant parties, including the car industry.
"The Commission always acts in the general European interest, not in
the interests of any one group or stakeholder," she told Reuters in
answer to written questions.
NEW TESTING REGIMES
PEMS have been used on trucks for years following a previous defeat
device scandal in 1998, which, like the Volkswagen case, was
discovered in the United States.
Early versions of the device, which cost around 150,000 euros
($166,335) each, were too heavy for cars, but they have since become
less unwieldy and are going on trial pending their mandatory use as
part of EU vehicle authorization from September 2017.
A VW spokesman said the company was already using the devices to
test carbon dioxide (CO2)and NOx emissions in research and
development.
Emissions Analytics CEO Nick Molden bought a PEMS in 2011, seeing a
business opportunity serving people who wanted to know why their
cars used much more fuel, and therefore produced more CO2, than
manufacturers promised.
An economist by training, Molden specializes in advanced modeling
techniques to help businesses extract profit from data.
His company, based in an industrial unit in Feltham on the western
edge of London, attaches the device to cars, drives them around and
collects the data, selling it on to interested individuals,
businesses and even regulators. So far it has gathered data from
1,000 vehicles, Molden said.

Business is brisk. Five major car makers subscribe to Emissions
Analytics' database and the company set up a Los Angeles branch in
2013.
Molden said the PEMS is a powerful tool but questioned how
effectively its use would be enforced given the long history of
industry, together with member states, diluting Commission plans.
Since he formed his company, Molden has been invited to sit on EU
working groups to debate proposed legislation in Brussels, and the
experience is instructive.
"It's clear for all to see the power of the automotive lobby versus
the number of specialists from the Commission side. German
manufacturers send their top engineers," he said.
Only a month after the VW scandal was exposed, Germany and the car
industry lobbied successfully for leeway to allow them to carry on
polluting above official limits up to 2021 and beyond.
They argued they needed the flexibility to protect the profitability
of an industry that provides around 12 million jobs, directly and
indirectly, and accounts for 4 percent of EU GDP, according to
European Commission data.
RESISTANCE IS INEVITABLE
Isolated EU officials have spoken out for the use of PEMS for years
to tackle diesel fumes. In 2011, then-Environment Commissioner Janez
Potocnik noted PEMS were already being used for trucks and said the
Commission was working to ensure the "necessary technical
developments" were completed by 2013 for cars.
But resistance to the system is inevitable, analysts say, as
carmakers are wedded to testing in laboratories using dynamometers,
which they say they provide a predictable, repeatable result.
By contrast PEMS are affected by many variables, such as different
altitudes and temperatures, known as "boundary conditions", a
spokesman for the European Automobile Manufacturers' Association (ACEA)
said.
Ongoing debate to define these boundary conditions legally could
amount to another watering down of standards, Molden said.
It is not clear how using PEMS would affect a system that has grown
up in Europe whereby the government agencies that put their seal of
approval on the cars -- so-called national type approvers -- work
with manufacturers to put the cars through tests.
That system has tolerated practices such as the use of specially
prepared cars, known as golden vehicles, which are primed to be as
fuel efficient as possible. Air conditioning is turned off, for
instance, and special fuel and tires are used.
The European Commission says PEMS will make it much harder to cheat.
But although the Commission is redoubling efforts to tighten the
regulations, it has stopped short of proposing a powerful
independent regulator along the lines of the U.S. Environmental
Protection Agency, the body that forced Volkswagen to admit its use
of defeat devices.
