I've certainly indicated very clearly to Yvo de Boer, the executive secretary of the United Nations framework group, that we have budgeted and are paying fully our contributions toward that. I think it's important. It's something that had fallen behind. As I said previously before the committee, we're committed to paying both our voluntary and our assessed contributions to the UN framework. I don't think there's any concern. I don't know whether the cheque has cleared or whether it's arrived. It's something we strongly support. We think it is important, obviously, from the fact that we have come forward with a clean development mechanism and have said we want to participate in it.
You asked me about our policy for 2020. Our regulatory framework for air emissions states clearly that we want to achieve absolute greenhouse gas reduction of 20% by 2020 in Canada.
