Thanks, Mr. Chair.
Ms. Parkinson-Marcoux, it's good to hear from you again. I was pleased to hear your comments about consumption taxes. A lot of Canadians hadn't connected the environmental aspects of a consumption tax. It's interesting, because in the debate that surrounded the government's decision to reduce GST by a point, what we heard mostly was not on the question of environmental impact but on the question of cutting a consumption tax, and its negative effect on savings levels, investment, and productivity in the country. It would have been a more productive thing to cut income taxes. It's interesting how you're talking about the shifting here. I just wanted to remark on that.
Perhaps I could turn to our colleague from the Suzuki Foundation, Mr. Marshall.
Mr. Marshall, I was really happy to hear that there is a study from the oil and gas sector. I think all of us would benefit from hearing more about the ability to reduce greenhouse gases. I know the forest products sector of Canada has already reduced its greenhouse gases with strong related air pollution reductions. They have reduced their greenhouse gases by 44%, using 1990 as a baseline in this country. It's interesting to see there's another success story and sector out there that could achieve—with some effort.
Mr. Freeman, I'd like to turn to your specific recommendation. I want to thank you for your notes, your comments, and your recommendations, because they're highly specific. They're good for us to work with. You mentioned the idea of creating new air quality zones. For Canadians who are watching or listening, I guess you're talking about dividing up the country into zones. You mentioned the specific areas where you have high pollution levels and high population levels.
The country is urbanizing much faster than we ever thought it was going to, to the point where we now know—I think it was Mr. Drouin who said this—that roughly 80% of the population lives in 12 or 14 cities.
Then you went on say that the emissions standards for those areas must nonetheless be in the most protective category of emissions standards. I didn't understand what you meant by that. Could you help us understand this? If we divide the country into these air quality zones and set standards, how would this work where there are areas that are more polluted than others, for example?
