We will leave that for a second.
Mr. Marshall, as my colleagues have said, you've made the connection between emissions in general and the two issues of air quality and climate change, and there's some debate as to which one to do first. Or do you do both at the same time?
Let's take the issue of intensity for a moment. The government is currently suggesting some intensity standards for the amount of pollution that's allowed out, as a way to measure it; that is, we'll go by intensity rather than say there's a cap on it.
Natural Resources Canada has said that within the oil and gas sector over the next 10 years there will be an improvement of 30% in intensity, just doing business as usual, but with projections of quadrupling, or more, production. What does this do for overall emissions, both of greenhouse gases and air pollutants, using intensity as your guideline?
