(John Connor, CEO Climate Institute): «The debate is shifting into even deeper reductions that we need to have beyond 2020 and it shows that the emissions reduction fund is just an inadequate tool to be the primary tool for emission reductions, while the renewable energy target is a critical target that we need to be strengthening, not weakening.

I would also very much like to see some costings of the emissions pathway being championed by the Worldwatch Institute — costings both of the climate change impacts which would still occur, and of the efforts required to reduce emissions to the proposed degree — because I think this particular mitigation scenario can be as valuable in getting us on track as has been James Hansen's promotion of 350ppm as a target.
