The biggest concern I see, is that we are trying to continue to affect change to the minor % of polluters. While the big 2 now, China and India are not playing part in the Accords. This goes against so many process improvement concepts that businesses have been utilizing for decades. You don't trim those things that will have a few % effect, but those that will have a large effect on the problem. Without the involvement of reducing the rampant pollution in China and India. What the other countries do is meaningless and will destroy their economies.
