Zac Goldsmith

If you tell people, 'that old banger of yours, we're going to tax the hell out of it,' they'll rightly tell you to get lost. But if you tell people that when they next buy a car, the tax will be adjusted so that the cleanest ones will cost less and the polluting ones will cost more, most people would say 'fair enough.'

We've all heard of the surveys revealing that teenagers think cows lay eggs, and others where children can identify more brand logos than trees, by a staggering margin. My view is that children will form a significant part of the green fightback. They instinctively understand the value of the environment.
