Meanwhile, the Conservative party received an F+ because it has chosen a "completely inadequate" target for reducing greenhouse gases and because it is relying on intensity targets to meet its goals.
So, all the other parties get at least a B grade. The conservatives are relying on so called greenhouse gas intensity targets, or emissions/dollar of GDP, which is a meaningless statistic. As many have pointed out previously, greenhouse gas intensity is a meaningless statistic and decreases naturally as processes grow more efficient and economies transition from a manufacturing to a service oriented economy. The GHG intensity dodge was invented by the Bush administration and the conservatives were happy enough to follow along.
So, as Harper turns his high profile and the utter fragmentation of centre/left of centre vote into an opinion poll lead, a reminder that ever other party in this race has at least a half way realistic climate policy.
Canada can’t really wait too long to get in front of this problem. I believe that the US will have something proposed/in place by 2010 and as Canada’s biggest trading partner, will be in enforce a carbon regime on Canada, so this may be moot.
