To mitigate the dangerous impacts of global warming to the greatest extent possible, various greenhouse gas stabilization scenarios have been proposed. Integrated studies are proceeding on emission pathways and the costs of achieving climate stabilization, as well as on the impact risks of global warming. This paper summarizes the existing knowledge on temperature rise, mitigation measures and impact threshold values, with a particular emphasis on climate stabilization scenarios. It also gives an outline of the AIM/Impact [Policy] policy support tool developed for integrated assessment of global warming, and reports on the results of analyses of global mean temperature increase, emission pathways, and global warming impacts under GHG concentration stabilization constraints.
