I think there are a number of things.
First, the G8 summit was preceded by the Canada-EU summit, which happened in Berlin on the Monday. Climate change was also on the agenda for that, and we ended up with an agreement with the EU that in effect recognized the commonality of our approach, the notion that Canada and the EU underline the need to reduce global greenhouse gas emissions by at least half by 2050.
So there was, I think, a significant meeting of the minds following the Prime Minister's meeting with the German Chancellor and with President Barroso of the EU. He also, of course, met with President Sarkozy and Premier Fillon of France in Paris on Tuesday.
And finally, at the G8 itself, I think he was credible and effective in terms of explaining to all in the room why we in Canada have accepted and are moving towards measurable targets, and why it's significant to aspire to an agreement that includes everybody around the G8 table, including the United States, and that reaches out to the major partner economies, the major industrial developing economies like India and China.
I would say, in those discussions, he and Prime Minister Blair were particularly effective in recapping for the other G8 leaders what essentially was on the table and why it was important to aspire to seize that opportunity and to continue to challenge one another to move forward. There were a number of times when he intervened just to remind people of what was in reach and that it really meant something; that it meant we would hold ourselves to targets, that we would work together to ensure that we were achieving something and that our partners in the developing world were achieving something.
He held out a level of ambition and commitment acknowledging that Canada had come a long way and that we had significant issues that we had to address and were addressing—so with real credibility—but I think he was very persuasive in making that presentation.
