LibDem magic - it will be so because we say so

Last Friday, the LibDems launched "new transport polices to create a zero carbon transport system by 2050." And no one noticed. Not even their website, which carried the press release, but doesn't seem to carry the document, -Towards Carbon Free Transport.-

We are given a few hints how they might achieve this mighty ambition, but are otherwise left to speculate. The hints are:

• Introducing a distance charge on road freight, related to weight and emissions, as an incentive to shift freight to rail, raising at least £600m a year
• Establishing a new 'Future Transport Fund' to fund a programme of investment on our railways; removing bottlenecks, providing more trains and reopening lines
• Backing new North-South and East-West high-speed rail lines to the best European standards to replace internal flights
• Toughening new legal limits on the average emissions of new cars sold in the EU, to be reinforced with a steadily declining total that reaches zero by 2040
• Introducing a new 'Climate Change Charge' on internal flights, except life-line routes, starting at £10 per ticket to help fund the 'Future Transport Fund,' which will generate at least £150m a year

So we will still be using trains, planes and automobiles, but they will somehow magically become zero-carbon vehicles. I'm looking forward to discovering how the full document explains how they will achieve this miracle.
