I think it's important to distinguish between the broad sustainable development objectives that Canada has as a country. For example, Canada wants to and aspires to become a low-carbon economy. That's a broad objective, and then the targets are the kinds of specific numerically measurable things that you're talking about. What is the target for the Government of Canada's own greenhouse gas emissions? What is the current level? What is the short-term target, the medium target, and the long-term target?
I can tell you another hat I've worn as co-chair of the City of Vancouver's greenest city plan, and this setting of short-, medium-, and long-term targets has been absolutely vital to the City of Vancouver's success in becoming one of the greenest cities in the world. In terms of climate change we had two specific targets. One for the city as a whole, and one for the city's own operations. We had both short-, medium-, and long-term targets with respect to both of them, and those targets and the public nature of those targets have driven progress so that Vancouver now has the lowest emissions of any city in North America.
