Lib Dems plan a £2,000 road tax (BBC) {tax on CO2 emissions!}

[eppur_se_muova]

The owners of cars which generate the most pollution would face annual road taxes of £2,000 under Liberal Democrat plans to tackle climate change.
***
Vehicles producing the greatest pollution - carbon dioxide emissions of 225 grams per kilometre or above - are currently taxed at £215 per year if they run on diesel fuel.

Petrol-fuelled vehicles currently face excise duty of £210. The annual charge is £200 for those powered by alternative methods of energy.

At the other end of the scale, owners of vehicles with emissions of fewer than 100 grams per kilometre are exempt from vehicle excise duty.

The Liberal Democrats' proposals state the £2,000 tax would apply to nearly 200,000 cars in the so-called 'Band G' - 8% of all new vehicles sold in Britain each year.

1. Don't get your hopes up.

1) They are still (sadly) the official "Don't Know" party - not going
to be in power 'just yet' - and by the time that they get power, all
of the good Green stuff they come out now with will have been traded
away for influence, money and votes.

2) To quote from the article:
> It would apply only to new cars, with exemptions for "essential"
> vehicles.

In other words, business as usual ...
