1 Exploring the Potential for International Mitigation Clubs for the Road from Paris - An initial exploration - Preliminary results Steven Rose and Richard Richels 15th IEA-IETA-EPRI Annual Workshop on Greenhouse Gas Emission Trading, Paris, France September 29, 2015

2 Motivation The Challenge Shifting global emissions trends to stabilize/reverse temperature growth (e.g., to avoid 2 C or? of warming) Aggressive climate targets likely expensive. Policy design important! INDC country pledges are just the beginning How will/can INDCs be implemented? INDCs take us to 2030 where do we go from there, and how? Important issues The opportunities for international cooperation? The implications of long-term policy for near-term decisions and opportunities? Building blocks to a more comprehensive international system? Aggressive action requires looking beyond sectors, borders, and

3 Sample of INDC statements regarding international market mechanisms USA: At this time, the United States does not intend to utilize international market mechanisms to implement its 2025 target. EU: No contribution from international credits. Russia: The INDC indicator is to be achieved with no use of international market mechanisms. Switzerland: Carbon credits from international mechanisms will partly be used. Mexico: In order to achieve rapid and cost efficient mitigation, robust global market based mechanism will be essential. Mexico s unconditional INDC commitment will be met regardless of such mechanisms, although these would assist cost-effective implementation. Achieving our conditional goal will require fully functional bilateral, regional and international market mechanisms. Norway: [Supports] inclusion of market based mechanisms in the 2015 agreement, and the opportunity to continue using units accruing from the CDM and JI. 3

4 Scope of Present Analysis Exploring opportunities for and implications of international cooperation between US, EU, and China in the form of tri-lateral trade in emission permits Emissions pathways under unilateral & tri-lateral action Emissions permit market volumes, prices, financial flows Regional power sector, energy system & economic implications 4

5 Scenario Design Exploring two key dimensions: Regional mitigation action: unilateral, bilateral or multi-lateral Post-2030 additional policy ambition: none to more Near-term policy Post-2030 policy Regional coordination INDC Pledge No additional ambition Unilateral to multi-lateral More aggressive Unilateral to multi-lateral Using MERGE a global intertemporal optimization integrated assessment model (economy, energy, & climate systems) 5

12 Initial Observations & Insights There is the potential for mutually beneficial small clubs The size of the permit market and whether a country is a seller or buyer will depend upon a variety of factors Coalition composition, individual emission reduction goals, relative marginal costs Permit trade could lead to substantial financial transfers & have trade balance implications Expanding the number of trading partners will likely increase the trade benefits for the whole coalition, but may change the distribution Long-term policies shape near-term actions, especially peaking & permit trade However, peaking emissions pathways create a challenge for emissions trading Interesting additional lines of inquiry International club composition, permit trade & technology, permit banking Could international emissions trading be a means of engaging countries, increasing global effort, increasing receptiveness to pledge verification? 12
