Well, yes and no. This issue suffers from the tragedy of the commons. If I reduce my emissions significantly it will have zero impact if I'm the only one doing it. The only thing it does is help me feel better about myself and lowers my standard of living. The only way to realistically solve this is collective action and that's what the government is for. I actually think that we also have been to gentle about this topic on general. I'm in favor of sanctions against countries who refuse to lower emissions.
