TORONTO - Bob Rae is calling for an end to partisan rhetoric on the politically toxic issue of carbon pricing.

The interim Liberal leader says the vicious partisanship that has characterized the debate on the issue so far is disingenuous.

And he says it's paralyzing the real debate Canadians need to have on what is the best approach to reducing greenhouse gas emissions.

He says some form of carbon pricing is inevitable and even the Conservatives -- who now rail against carbon pricing as a "tax on everything" -- have admitted it in the past.

Rae's call for a more reasoned approach to the issue came during a major speech in Toronto, the text of which was made available in advance.

The wide-ranging speech focuses on the need for federal leadership to ensure Canada's resource wealth is exploited in a sustainable, responsible fashion that will produce widely-shared economic benefits.
