"How may the G20 countries take a lead on facilitating the global transition to decarbonized societies?"

Scientific evidence suggests that cumulative GHG emissions have already caused climate change, which has not only tolled victims all over the world, but quite often charged disproportionally high costs to the poor segment of the world. Substantial mitigation actions are likewise needed to avoid an irreversible catastrophic change in ecosystems that underpin human survival itself.

As a group of world leading countries, the G20 is expected not only to pioneer ambitious actions for transition to low-carbon or decarbonized society, but to also to lead international cooperation in the capacity development of less developed countries for implementing and financing these ambitious actions.

This policy brief, produced by a collaboration between multiple organizations, offers six proposals for how the G20 should take the initiative in devising and implementing these mitigation efforts for transition to decarbonized society.
