I think, although the hearts in the right place, it doesn't seem like the best way to do it.

First, just targeting CO2 emissions will probably do more harm than good, since there are other contributing gases that probably should go with it (don't remember which though).

Second, some of the biggest emitters didn't sign on, so it's largely ineffective anyway.

Third, setting targets instead of having an actual plan tends to fail. Leaving it up to individual countries only hinders progress towards the goal.

It doesn't help that the Liberals sign the thing, waffle over an actual plan for a few years, then turn around and try to tell the current government to come up with a plan. If you commit to it, they should have gotten a plan together right away.

EDIT: Oh ya, and the idea of CO2 credits sounds wrong. If your gonna reduce the pollution, reduce it, don't pass it around...Sounds like a new currency.
