ConservativeHome highlights a speech at the LSE in which (despite what I assume to be an error in the first sentence) Cameron today says that whilst they will want to increase environmental behaviour modifying taxes, they will want to use this to cut taxes elsewhere.

Of course they already know that the Lib Dems have specific and costed taxation proposals that use green taxes to cut four pence off the basic rate of income tax and take many low income earners out of income tax completely. We also have a long standing commitment to replace the Council Tax (though of course you know I don't agree personally with our replacement Local Income Tax) which deals nicely with what turns out to be the most hated tax in today's annual Tax Payers Alliance survey, again highlighted yesterday by ConservativeHome. And our "Green Mortgage" proposals will help households deal with their most worrying expense - their fuel bills.

So Cameron, what are you and Osborne going to cook up to beat that? And when? You can't go on just blathering and blustering indefinitely with vague and vacuous platitudes to your CH readership. You're certainly not ready for government if you can't even tell us what you're going to do on taxes.

Speaking at the LSE David Cameron has crushed any idea that the balance of green tax measures under a Conservative government will be cuts to encourage good environmental behaviour rather than tax rises to discourage 'brown behaviours':

"By using green taxes as extra stealth taxes, Gordon Brown has given them a bad name.  I’m determined that the Conservative approach will be different. With my Government, any new green taxes will be replacement taxes, not new stealth taxes.

In a few days, our Quality of Life Policy Group will publish its report. It will contain many recommendations on tackling climate change, at home and abroad, including recommendations on green taxes.  As with all the reports in our Policy Review, we will study its proposals carefully.

But let me be clear.  We will raise green taxes, and use the proceeds to reduce taxes elsewhere.That is the right direction for the environment and it’s the right direction for our economy. It is the best way to deliver the green growth that must be our aim."
