Voters not as green as cabbage looking
Most voters believe "green taxes" are more about raising money than helping the environment, a BBC poll suggests.
All three main parties say they want to use the tax system to encourage more environmentally-friendly behaviour.
But the Populus poll suggests they may have a fight on their hands convincing voters there is not a hidden agenda.
Some 62% of those polled said they thought green taxes were just a revenue-raising measure and nearly half were against the idea altogether.
