People have got to get used to making low carbon choices. If they have a direct incentive to do so they will think about it. Many times a day you have a choice between a low carbon option and a high carbon option, whether it is at home or at work.

For the first time perhaps since Margaret Thatcher, we will have at the head of the Conservative Party someone who is genuinely an equal match for Tony Blair.

The next four years, there won't be a week that goes by without a discussion of climate change. It's a naturally Conservative issue.

I personally think that a couple of pounds a week - maybe rising to almost £3 a week - is a reasonable price for Britain to achieve a degree of energy security to reduce its total dependence on fossil fuels and to honour its commitments to cut green house gases.
