The UK sees things differently, though, and is proposing domestic laws that mandate carbon emissions:
Milliband said failure to meet targets could land governments in court. Governments that fail to meet the stipulations of the bill will be subject to judicial review. It will be for the courts to decide what sanctions to apply," he said.
Honestly, I can't think of a better way to bog down the process of cleaning up the enivironment than getting the courts involved.
Now, if they really wanted to lower carbon emissions, they could spend lots of money replacing existing power plants with solar and wind power. But that would require action rather than vague promises to fix the problem later, which is much easier.
