Recently a shock admission by Ministers that encouraging uptake of diesel cars may have been a mistake, due to their unexpectedly high nitrogen oxide emissions, has caused a backlash against diesel run vehicles.
The Society of Motor Manufacturers and Traders (SMMT) has praised the new Euro-6 standards which will reduce limits of the air polluting gas nitrogen oxide. In addition, the introduction of a new "real world" testing procedure for cars could help to clarify exactly how much cleaner newer diesel models are.
A news article in the Guardian reported the following:
“Ben Barratt, an air pollution expert from King’s College London, says the early implementation of the new test is critical for the success of the regulations.
“In the absence of a real-world test we have to question these figures because history shows us that past performance has not delivered,” says Barrett.
“The sooner the real-world test comes in the better, without doubt. Because we will not know whether to trust the Euro-6 figures until that test comes in. Cities around Europe are reliant on Euro-6 delivering the reductions it is supposed to. If Euro-6 doesn’t deliver then many parts of Europe, including London and other cities in the UK, will continue to fail to meet European Union air quality standards.””
So the real question is, are diesel cars actually worse than their petrol equivalents? They’re definitely not better than electric that’s for sure.
