The work that I've seen since the Kyoto Protocol was signed suggests that none of the plans put forward by any of the governments would get us there. This is true about this plan, as it was true about previous plans. I think we're not understanding what level of effort is required to get us to emissions reductions.
If the question specifically is whether we are on track to return to 1990 emissions, given the policy instruments in place now it's hard to make a case that we are.
