A number of countries, in announcing or suggesting their 2020 goals, have described certain conditions for those targets. For example, the European Union has articulated a 2020 goal that's in legislation. It said it would go to 30% below 1990 levels, provided that other countries achieve comparable reductions and that major developing countries also take meaningful steps. They have also attached conditions to the outcomes of the negotiations on international offsets. Japan, in announcing its target, has described similar conditions.
We should look to the representatives of these countries to describe their conditions. I think a number of people have described the conditions under which they would implement certain measures in a global agreement. Australia has also made such conditions known. Of course, if those conditions are not met, it implies that those countries would commit to achieve less.
