Jeremy Hobbs, generalsekreterare för Oxfam International, sa idag:
- The rumours around Copenhagen are of a political deal to keep us below 2°C but no-one is mentioning the scale of emission cuts needed to get there. There is more talk about a $100bn per year for developing countries by 2020 but no-one is talking about who's going to pay, whether the money will be new, or where it is coming from. Everything is left to play for on the final day. We need guaranteed action and more substance - leaders won't sell this deal on trust alone.
