The Prime Minister has mentioned this in his own interventions. He was very explicit in referring to this as a new step forward for the United States, a willingness to commit to a process of setting targets. He made that explicit in his direct address to the President, and in his address to other G8 members, as a significant step forward. At the same time, he made clear to all in the room, including the U.S., the importance of setting targets, the importance that we all have to bind ourselves to a process. As he said later, this is particularly important for Canada because of course we share a border, we are economic partners with the United States, we share an airshed with the United States.
So it's seeing the U.S. move to a new position where they're willing to set targets and move forward. It's important not just for the G8 but for Canada too.
