2 Overview Why markets? The efficiency of markets Permits vs. taxes Carbon markets EU Emissions Trading System The Kyoto mechanisms Voluntary markets The future of carbon markets Creating a market Policy environment: the global deal

3 The need for emission cuts From the Stern Review

4 United States Can-Aus-NZ Russia Japan W. Europe E ITs Middle East China Latin America Other Asia Other Africa India Population (Million) Emissions (Tonnes of Carbon Per Capita) South Africa Developing country (non-Annex I) countries Sharing the abatement burden

5 The benefits of emissions trading Source: Manne and Richels (1998) US$ billion Cost of meeting Kyoto targets for the USA, 2010 Effectiveness Track record in reducing emissions Efficiency emission reduction at lower costs Integration Finance and technology flow to emerging markets

6 Taxes vs permits Economic efficiency argument Taxes: certain cost, uncertain quantity Permits: uncertain cost, certain quantity Optimal choice depends on the slope of marginal abatement, damage cost curves (Weitzman)

7 Taxes vs permits Marg. Abatement Cost Flat MB curve Marg. Abatement Cost Steep MB curve target MAC MB

8 Taxes vs permits Marg. Abatement Cost Choose tax Marg. Abatement Cost Choose permits target MAC MB

9 Taxes vs permits Political economy arguments are more conclusive International carbon tax agreement difficult to achieve Domestically, industry prefers (grandfathered) permits

25 11,000 installations in 27 EU countries Energy, refining, minerals, metals, pulp&paper Annual compliance requirement Targets set in National Allocation Plans Mostly grandfathering, some auctioning Possibility to import Kyoto carbon At least three trading phases Phase I Phase II Phase III EU Emissions Trading Scheme

30 Chicago Climate Exchange Self-described as “world’s first and North America’s only voluntary, legally binding, rules- based GHG reduction and trading system” Established in 2000 with currently 312 (voluntary) members power, automotive, chemical industry; banks, universities, municipalities; project developers, offset aggregators, NGOs Six gases, both allowance-based and offset credits In 2006 about 10.3 MtCO 2 e were transacted, worth US$91m; as of July MtCO 2 e had been traded on the exchange

34 New Zealand (NZ ETS) Starts trading in summer 2008 with forestry Covering all emissions by 2013 (industrial processes by 2010) Australia (AETS) Starts trading in 2011 Covering >70% of emissions (ex. Agriculture, forestry, fugitive emissions) Japan Focus on voluntary schemes (JVETS) Asia - Pacific

35 Permit allocation Auctioning, grandfathering, benchmarking Scope Difficult sectors like agriculture, transport Upstream vs. downstream Safety valves against price spikes Carbon leakage and competitiveness Linking with other schemes CDM imports Linking with other schemes (e.g. NZ – Aus) Open issues

36 Carbon markets in practically all OECD countries Regional schemes linked by an extended, enhanced CDM Underlying assets: 7.5 billion allowances, worth 200 billion? Of which > 4 billion in a US federal scheme? Trading volume: 8 – 13 billion tCO2 What is the global deal? Long-term: Markets in 2020

37 The “global deal” Long-term target: a 50% cut by 2050 For a ppm stabilisation target Consistent with G8, EU rhetoric Equitable burden-sharing Up to 80% cut in developed countries Developing countries get help on technology, carbon finance The next 6 months are crucial Target: agreement by 2009, ratified in 2012 Next step: G8 Japan (summer); COP (Poznan)
