The leadership of the EU states know this well. They also know that industry in the EU is a hugely important employer and a major shift to importing more goods would be very destabilizing. So what does it tell you that they choose to move ahead with this policy, even though it means potentially weakening their economies relative to the competition? To me, it says they finally see that the consequences of not acting to mitigate climate change are unacceptable, and that there's no solution without risk left.
