With your permission, Mr. Bigras, I will answer that question in English.
One of the things I was trying to say in my opening remarks is whatever level you choose to stabilize and whatever pathways you choose and whatever contribution you choose, it's informed by science, but it has also to be as a result of a political process. There are political decisions to make, political decisions because it depends on values, what you value and, among what you value, what you do not wish to see disappear as a result of climate change.
It's also a matter of our values when one talks about the level of ambition. What level of ambition does Canada want to display internationally? That's as a result of how we are regarded internationally, but also, as I said earlier, as a result of what we want to achieve as an economy. So although you can go through scientific arguments and say yes, as I think all four of us have said, we need globally to reduce emissions by 2050 by at least 50%, you have to think of what part of that 50% is Canada going to contribute. And that is partly scientific, but it's going to be partly political.
My own view is that you need a level that is going to unleash the innovative strengths of Canadians and be a real challenge. It needs to be ambitious. So in that argument, one might say that the stronger the level of ambition, the better.
