I think the Stern report for Canada would be useful, but I'm definitely in the camp that says what we lack is not information; what we lack is political will at this stage. We know what needs to be done. We understand the science. We know what policies work. We know what technologies need to be implemented. If I had a choice between the Prime Minister saying we're going to have a Stern review or him saying we're actually going to get serious about tackling climate change by putting policies into place, I'd pick number two.
