Mitigation or emission reductions is at the very heart of these negotiations. In Copenhagen we're looking for developed countries to commit to binding economy-wide quantified emission reduction targets for 2020. We are also looking to establish targets that place us on a pathway of achieving deep aggregate reductions by 2050.
From developing countries, we are seeking actions that are listed in an agreement and that are subject to review. Clearly, to be environmentally effective, we will have to draw in the major emitters in the developing world. We will need cooperation from China, India, Indonesia, Brazil, and Mexico. At the same time, we are working in the agreement to undertake much broader action. There are more than 192 countries involved in these negotiations, most of them developing countries. We want to build a regime that enables broad participation and broad action from countries that are smaller but still significant. Columbia, Peru, and others will be significant.
In addition, significant action on forests could be a very important outcome of these negotiations, and on this matter you might also have to address some countries that are not as far along in their development.
