Just so people remember, it was the Lib Dem Tax Commission that put forward the idea of a two grand tax on gas guzzlers and a tax to reflect the effects on climate change of air transport and travel.

According to the Observer the environmental audit committee of MPs agrees and will set out on Monday a range of ways of achieving both. But we must also be plugging the fact that the Lib Dem proposals would not increase the tax burden overall but take many low paid people out of income tax altogether and reduce everyone's basic rate to twenty per cent.

As a side note, if you read this before it goes pay-per-view I am slightly annoyed to know that my Ford Ka is relatively speaking the most regressively taxed of a range the Independent reviewed. Oh well, I guess that means I stand to gain relatively when they put it right. But I'd rather be driving the Bentley any day!

So, now that everyone appears to agree with our current eco-tax proposals, I hope we will get on and develop our Land Value Tax strategy to balance things out for people unable to afford to live close enough to work to avoid the longer climate changing commutes. If eco-taxation's time has come, it won't be long before people begin to understand that location values are part of that whole eco-package.
