Diesel engines have been demonised for their emissions but the technology has already cleaned up its act.
But the most effective measures will be unpopular.
It's about time Europe ditched the diesels – so what are the alternatives?
South African consumers are paying far too much for petrochemicals products.

The VW emissions scandal is an opportunity to forge ahead with fuel cell technology for cars.
The emissions scandal has already taken its toll on Volkswagen.
It's likely that many people knew Volkswagen was cheating on emissions tests, including the engineers who built the 'defeat device'. But why did no-one at the car maker blow the whistle?
Smog over car-heavy Los Angeles.

Global scrutiny has pummelled VW shares.
The market reaction to the VW emissions scandal is just like that of a jilted lover.
Still a lot of good under the hood.
Current clean diesel technology is more than capable of meeting tough air quality rules while still delivering excellent fuel performance. Biofuels could make it even cleaner.
Eleven million cars worldwide could be affected by the scandal.
Volkswagen's cheating allowed its vehicles to pass rigorous emissions testing, giving customers maximum driving performance at the cost of the environment and our health.
