Mr. Chairman, the minister did in New York announce her intention to issue a notice of intent to regulate in the area of HFCs. That is important, in a sense, because of the relationship between the two environmental issues of climate change, on the one hand, and ozone depletion on the other hand. The committee members will be aware that the Montreal protocol is a very successful international agreement that addresses ozone depletion. The first key substance that was attacking the ozone layer was chlorofluorocarbons, or CFCs. The Montreal protocol helped to reduce, and then phase out, CFCs. Then the world moved to HCFCs, a less potent type of destructor of the ozone layer, and that was quite successful. Then the world moved to HFCs. The good news about HFCs is that they don't destroy the ozone layer. The bad news is that they are a very potent greenhouse gas. So, in a sense, you were trading off one problem for another problem.
What Canada has been trying to do internationally is to work with the United States to get increased attention on the importance of stopping this trend towards the increased use of HFCs, which, if left unchecked, would lead to very significant greenhouse gas emissions and make climate change worse. What the minister announced in New York was the intent for Canada to bring forward a regulatory initiative that would be aligned with that of the United States to try to put a brake on the emissions of HFCs.
