The Next Frightening Step To Meeting Emission Targets?
Friday, 11. December 2015
2 years ago I reported on some comments made by an environmental and technical expert who said that European targets for emissions were not only becoming difficult to meet but impossible to meet.

He explained that an internal combustion engine burns fossil fuel which has the negative effect of emitting undesirable gasses and particles that pollute the air. That is a fact that can’t be changed. The objectives to continually reduce the gasses is fine and very environmentally friendly but technology and additives can only go so far before the targets are impossible to meet.
We all know that the harder we drive our cars the higher the amount of fuel we use. We may get from A to B quicker but we use much more fuel in doing so and it goes without saying the more fuel we use the more gas we emit from the exhaust. So as we reach the limit of gas reduction is the next step a control on the way we drive.
The only measure used at the moment is CO2 but will NOx enter the equation following the VW debacle? And by halving the NOx emissions target (Euro VI diesel engines) have we created an impossible task for the manufacturers? As we know fuel consumption figures are shown using different driving conditions, urban, extra urban and combined.
They may not exactly reflect actual driving conditions but we have three, often very different figures so why do we have just one CO2 emission figure as well as other singular gas emission figures when clearly they must differ from 10mph to 100mph? It was clear, even 2 years ago when I expressed my opinion on this subject that some creativity would have to enter the equation if targets were to be met.
However, I didn’t expect that creativity to extend to out and out deception. And whilst there wasn’t a murmur when the new Euro VI emissions came into effect on the first of September, following the VW debacle many manufacturers have announced that they are struggling to meet the Euro VI targets – strange that isn’t it? So what next? Will we see driving style and speed controls?
Limits on motorways dropped to 60mph and a drop from 30 to 20 around town? Or maybe cameras that can measure acceleration away from lights to stop drivers from pretending to be Lewis Hamilton? All very worrying for us petrol heads! By Graham Hill
