60mph motorway speed plans suspended

Just been reading that plans to being in an enforced speed limit of 60mph on 2 sections of motorways have been shelved for 18 months to allow the Highways Agency to come up with alternate ways of reducing pollution on a section of the M1 in Derbyshire and some of the M3 near Surrey.

Seems all sorts of suggestions have been proffered with even the possibility of banning high polluting vehicles at certain times. Not sure how that would work from a hauliers point of view though.

It was hoped that the more fuel efficient, therefore less polluting vehicles would have had a greater impact on the pollution however its reported that these are taking longer to become the higher percentage of road users.

Looks like they are trying to copy what happens around me locally with the hard shoulder on the M42 used at peak times to ease traffic flow. Be interesting to see how this goes as it does seem to work.

Being a humble plumber I'm not really up on scientific facts, but I would have thought regardless of the speed you are traveling at the same volume of pollution will be produced over the same distance traveled but one will be achieved quicker than the other. Any discrepancies would be minimal. Besides most people drive well over 80mph on the motorways nowadays......

I think the science behind it is - the slower the speed the greater the MPG, ergo less pollution.

My car, now run in, gives me around 50mpg most mornings on my 7 mile run to the office, assuming i dont get held up and i get a clear run. If i do get held up in the village of Studley then it drops to mid 40's

On the motorway, (depending on how close i stick to the speed limit and more like Barneys figure above  ) i get around 40-45mpg, which i would get more from if i dropped to around 60mph. 2 problems for me - 1) i like speed & 2) takes longer to get there!
