'Something weird' in European car emissions tests, say analysts | |
(34 minutes later) | |
Environmental campaigners say they believe that cheating similar to what happened at VW is going on in Europe. | Environmental campaigners say they believe that cheating similar to what happened at VW is going on in Europe. |

Industry bodies deny there is any deliberate deception in European tests. | |
While there has been widespread indignation at the scale of VW's manipulation in the US, the number of diesel cars being used across the states mean the impact on the environment and air quality is likely to be limited. | |
But in Europe it is a different story. Over half the cars purchased in the EU in 2014 were diesel powered. | But in Europe it is a different story. Over half the cars purchased in the EU in 2014 were diesel powered. |
Several European cities, including London and Paris have had significant issues with nitrogen dioxide, a harmful gas produced as a result of diesel use and linked to increased deaths from heart attacks and asthma. | Several European cities, including London and Paris have had significant issues with nitrogen dioxide, a harmful gas produced as a result of diesel use and linked to increased deaths from heart attacks and asthma. |
But according to the latest research from Brussels-based Transport & Environment, only one in 10 new diesel cars sold in Europe meets the standards for emissions for nitrous oxides (NOx). | But according to the latest research from Brussels-based Transport & Environment, only one in 10 new diesel cars sold in Europe meets the standards for emissions for nitrous oxides (NOx). |
"New diesel cars should be achieving 80mg of NOx per kilometre, typically an average diesel is producing five times more than that at the present time," said Greg Archer, a former UK government adviser and now head of clean vehicles at Transport & Environment. | "New diesel cars should be achieving 80mg of NOx per kilometre, typically an average diesel is producing five times more than that at the present time," said Greg Archer, a former UK government adviser and now head of clean vehicles at Transport & Environment. |
Extreme lengths? | Extreme lengths? |
Testing in Europe is said to be more open to manipulation than in the US because the evaluations are carried out by companies paid for by the manufacturers, and they are generally done before the cars go into full production. | Testing in Europe is said to be more open to manipulation than in the US because the evaluations are carried out by companies paid for by the manufacturers, and they are generally done before the cars go into full production. |

"We think that gaming will give you about a 25% difference, we can't explain how these vehicles are achieving real world performances 50% higher, unless something weird is going on in the way they are being tested, that would point to something similar (to VW), a different sort of defeat device being used." | "We think that gaming will give you about a 25% difference, we can't explain how these vehicles are achieving real world performances 50% higher, unless something weird is going on in the way they are being tested, that would point to something similar (to VW), a different sort of defeat device being used." |

"The EU operates a fundamentally different system to the US - with all European tests performed in strict conditions as required by EU law and witnessed by a government-approved independent approval agency," said the chief executive of the UK's Society of Motor Manufacturers and Traders, Mike Hawes. | "The EU operates a fundamentally different system to the US - with all European tests performed in strict conditions as required by EU law and witnessed by a government-approved independent approval agency," said the chief executive of the UK's Society of Motor Manufacturers and Traders, Mike Hawes. |

Be it gaming the system or outright cheating, researchers including Prof Alastair Lewis say the impact of dodgy data on UK government attempts to clean the air are significant. The UK is currently being prosecuted by the European Commission because of its inability to reduce levels of nitrogen dioxide in many locations to safe levels. | Be it gaming the system or outright cheating, researchers including Prof Alastair Lewis say the impact of dodgy data on UK government attempts to clean the air are significant.

"The UK has terrible problems with nitrous dioxide in city centres but the government can only work with the data provided by manufacturers and that has proved to be highly unreliable," said Prof Lewis. | "The UK has terrible problems with nitrous dioxide in city centres but the government can only work with the data provided by manufacturers and that has proved to be highly unreliable," said Prof Lewis. |
