For the first time, the Green Party of Canada is heading to the polls looking down right mainstream.

"It very well might be our first environmental election where that issue is top of the agenda," says University of British Columbia political scientist professor Fred Cutler.

It's good news for the party's star candidate, Adriane Carr.

"I hope the environment is the big issue and, in fact, the ballot question: the question that people go into the ballot box and mark an 'x' beside the green," says the Vancouver-Centre Green candidate.

The Liberals are also courting the earth-friendly vote, including Burnaby-Douglas candidate Bill Cunningham, who is touting his party's carbon tax plan.

"The plan Stephane Dion has proposed -- the green shift -- is admired by economists and environmentalists alike as being ground breaking," Cunningham told CTV News.

But it's not admired by the conservatives.

"At the end of the day I think it's clear middle class people in particular are going to pay for the lion's share of what is essentially a tax grab," Conservative MP Jason Kenney told CTV News earlier this year.

While shying away from a carbon tax, the NDP wants to shift gas tax revenue to public transit.

British Columbians are the only people in the country paying a carbon tax on gasoline. The question is whether they're ready to pay even more for an environmentally friendly federal government.
