It has been announced that the Lib Dems intend to ban all petrol and diesel cars from the roads by 2040.
Good luck with that then!!
I can't find anything about it on the Lib Dem web site, but
the Telegraph has this story. It would appear that it is a proposal to their annual conference and so isn't policy, and is quite disingenuous of the Telegraph to title the story as if it is: "Lib Dems: ban petrol and diesel cars from UK roads by 2040".
I think it's a useful proposal. We're talking 23 years away remember, so that's plenty of time to develop low-carbon transport, and if we really do have a global warming problem it will take a timely decision like this to encourage some positive action. Telegraph readers may harumph, but doing nothing is not a good option.
Obviously, over 23 years I would guess that the policy may well be refined, but I think the idea of banning petrol and diesel per se is misguided, and what is necessary is a ban on fossil fuels - diesel is a particularly useful fuel having a high energy density but also being difficult to ignite in a crash, so for me the holy grail is to produce a non-fossil diesel-like fuel without growing it on valuable agricultural land with all of the environmental problems that go with it. There are already non-food crops that produce diesel quite efficiently, but they don't grow in Northern Europe and our own energy security is important. We have some wind and wave power, so if an industrial process could be developed to turn that electricity into diesel that would be excellent. It would also be good if we could develop nuclear fusion in addition to wind and wave.
I still think that very much more could be done to reduce road miles though. Commuting isn't good for anyone, so if commerce could come to terms with working-from-home that would help.
I'm assuming of course that domestic road miles contributes significantly to our national CO2 footprint - because if it doesn't then this is just a pointless exercise.
