Mr. Speaker, in 1993 I was part of the global climate change task force that toured five different cities across the country. We were dealing with Rio at that time. Those very questions were asked because that was how primitive the debate was at that time. We were at the infancy of the debate and starting to draw attention to climate change. I think the global climate change task force came away satisfied that the issues of climate change and global warming had a secondary impact and that was the air pollution side. There were two parallel tracks.
One of the recommended methodologies by which Canada will meet its Kyoto targets will be to look at the urban transit strategy. The emissions that will be avoided by a rapid transit urban strategy will include, not only CO
2
, but also other poisonous hydrocarbons such as mercury. A number of pollutants will be eliminated as we seek to reduce other greenhouse gas emissions. Poisons will be reduced in concert with the reduction of greenhouse gas emissions.
I hope that answers some of the hon. member's questions.
