Surely the first thing that any government with a real green agenda would do is ban large cars. Do we still need to be asking whether a 3-litre engine consumes more resources than a 1.5?

And this is enough reason to ban them. Of course, I hear the free-choice lobby up in arms telling me that those who can afford should be able to choose ... but this is no longer a question of economics, but of sharing physical resources.

For all the inequalities in this world, money is the greatest. But global warming will eventually be a question of life and death, not real estate. So is it just the richest who have the rights? The conclusion is of course that no government yet has a green agenda. It's all just politics.
