The EU ETS
• 27-state multinational CO2 trading system • Classic cap-and-trade covering large sources
– About 45% of EU CO2 emissions
• Hybrid implementation of Kyoto Protocol
– Trading and non-trading sectors – Decentralized cap within a cap with CDM linkage
• 2005-07 trial period, 2008-12 second period, and post 2012 periods
MIT CEEEPR
The EUA Market
• Mostly futures trading in front contract
– Also, spot but 10-15% of total volume
• OTC market initially, but exchanges developed quickly and account for 30-40% of volume
– US allowance markets all OTC
• An EUA is a downloaded AAU, but non-EU AAUs are not acceptable; CERs/ERUs are.
– Also any linked systems: probably Norway

Weekly observations
MIT CEEEPR
Three Prominent Features
• Higher than expected initial prices
– Energy price relations – Adverse weather – Institutional features
• Sharp adjustment upon revelation of lower than expected emissions
– All prior information was speculative – Similar response in US SO2 program
• End-of-period price separation
MIT CEEEPR
Temporal Trading: An Important Pricing Feature
• Unrestricted intra-period banking and borrowing, but none between trial and subsequent periods • Explains 1st and 2nd period price separation in 2007 • Inter-period banking expected from 2008-12 on

EU ETS: Over-allocation
• Not an issue until first data release • Muddled concept; conflated with being long • With inter-period banking constraint, sure to be either long or short • Concept also used to imply no abatement; data are showing abatement • Inherently difficult problem of ensuring shortage with ambition is modest; ex post rarely coincides with ex ante

MIT CEEEPR
Allocation in the EU ETS
• Delegation to member states to decide total and distribution with 95% grandfathered • Member state decisions subject to review by the European Commission
– In practice, limited to the proposed totals, and – No ex post adjustment or quota management
• Huge data problems at installation level • Extended discussion between industry and government on data and allocation principles
MIT CEEEPR
What Choices were Made?
• Allocations based on recent emissions
– Benchmarking proved infeasible
• Shortage allocated to the power sector
– More abatement possibilities & no competitive problems
• Very little auctioning (4 MSs & 0.13% of total) • New entrant and closure provisions
– Potentially distorting effects but ubiquitous
MIT CEEEPR
Principles or Politics?
• Near universal disapproval of grandfathering, yet always chosen
– Is there more than just politics & lobbying?
• Unacknowledged social norms?
– Lockean prior use and squatter rights – EU variant: production conveys the right
• A convergence of fairness and expediency?
– Allowances permit Coasian separation of efficiency and equity – Assign rights to mitigate financial impact of the change in prices and rules
MIT CEEEPR
NAP2 Differences
• More auctioning: 11 MS’s, 3% of total • Some increase in benchmarking, but still little • Substantially lower caps
– Based on aggregate 2005 Verified emissions – All East European MS’ suing in ECJ – Wide variation among MSs (-19% in Denmark to +33% in Lithuania (relative to 2005 emissions)
• Updating at micro level only in East Europe

The Next Steps for the ETS
• The East European challenge in NAP2 • Expanding the scope: Aviation proposed • The ETS (post-2012) Review: Dec 07
– An EU-set cap? -20% from 1990 – Much higher auctioning share? – More harmonized allocations?
• Maintaining a credible price
– Overlapping mandates (i.e., renewables) – International market linkage (CERs, greened AAUs)
MIT CEEEPR
The EU ETS as Prototype
• A multinational trading system with a uniform price on carbon throughout the EU • The east/west parallel to the global north/south divide
– Differing criteria for EU15 and Accession-10 – Differing responsibilities for non-covered emissions
• What made all 25 join up?
– The European idea? – Or the benefits of the club?
MIT CEEEPR
The Geopolitical Importance of the EU ETS
• The Fact on the Ground • The Pioneering Example
– Learning experience for those who follow – The subtle influence on the American debate
• The €20/tonne incentive and the CDM
– Attracting interest from those outside – Influencing Chinese and Indian preferences
MIT CEEEPR
The Challenges Ahead
• Continuing the EU ETS and keeping it open • Avoiding trans-Atlantic acrimony in global environmental diplomacy
– First step is linking EU and US systems
• Developing combination of community and interest that will attract others (as in the EU) • Finding a multinational institution to coordinate and negotiate accession/membership
