EU adopts world’s first test for diesel car emissions ‘on the road’

EU regulators have today agreed new test procedures that will, for the first time, measure the ‘real world’ emissions of diesel cars under the Euro 6 air quality standard. It will require vehicles to be tested on roads rather than in laboratories, overcoming obsolete tests and ‘cycle beating’ techniques used by carmakers to achieve results in tests many times lower than actual air pollution emissions on the road.

Rail tunnel financing saves congestion charge in Gothenburg

The city council in Gothenburg has decided to keep the city’s congestion charge despite the result of a referendum held last September that called for its abolition. The decision to maintain the charge was taken in order to protect funding for a new rail tunnel under the city centre.

UK car industry's desperate attempt to wash out diesel cars' image

Today's greenwashing of dirty diesel by the UK car industry is an attempt to hide the fact that a typical diesel car emits 10 times more nitrogen oxides than an equivalent gasoline car, sustainable transport group Transport & Environment has said. With 12 out of 13 Euro 6 diesel cars failing to achieve the Euro 6 limit in tests conducted on the road, the SMMT is ignoring the inconvenient truth that new diesels can’t reach the limits agreed back in 2007 without fitting new technology.

France moves against diesel

France has set itself on course to displace diesel as the preferred fuel for private cars, with the prime minister describing French pro-diesel transport policy as ‘a mistake’ and announcing financial incentives to replace the country’s extensive diesel car fleet in order to tackle air pollution. The mayor of Paris has also announced plans to largely ban diesel cars, buses and trucks from the city by 2020.

Realistic real-world driving emissions tests: a last chance for diesel cars?

Sketch of a book (default image for publications

Air pollution emissions limits for cars, vans and trucks (Euro Standards) have been progressively tightened, on paper, over 25 years but have failed to deliver real-world improvements for several key pollutants, notably nitrogen dioxide. This is because obsolete tests and “cycle beating” techniques have been used by carmakers leading to levels of emissions from some cars many times higher on the road than in laboratory tests. In October 2014, the Commission will be discussing progress and next steps with EU member states. This paper outlines key issues for member states to ensure that the new real-world (PEMS) tests are robust and representative of real-world driving in order for emissions to decline on the road. 

Brussels and Gothenburg highlight difficulties of tackling congestion

The unofficial capital of Europe is the most congested city in Europe, according to the latest ranking of congested cities, but opinion sampling and a vote in Gothenburg suggest public willingness for tackling congestion is not great.

High diesel NOx emissions ‘likely for decades’ due to failing tests

High levels of nitrogen oxides (NOx) in cities, caused by diesel cars, are likely to persist for decades, the UK Government was recently forced to admit. In evidence to the European Court of Justice, in a case brought by Client Earth, the government admitted it would be at least 2030 before London, Leeds and Birmingham meet nitrogen dioxide standards that should have been achieved in 2010.
