There are two aspects here. First of all, the problem of climate change that we are facing is global and worldwide. Whatever action Canada takes, regardless of what all other countries do, will have essentially no effect on the problem itself. Canada produces about 2% of greenhouse gas emissions. This is why we have to see this issue as an international relations problem. There needs to be an international approach where large emitters, like Canada, play a very special role.
I understand where your question is coming from, but I think that we need clear targets to enable Canada to be a player on the international scene. When all the players worldwide play together, we will have an impact on the problem. That is why targets are important. You have to look at the level of effort.
