1. 30/10/2006 MARKET BASED MECHANISMS TO FIGHT CLIMATE CHANGE Jean-François Conil-Lacoste Chief Executive Officer, Powernext SA APEX Conference October 30, 2006 Seoul

2. 30/10/2006 CLIMATE CHANGE IMPLIES A POLITICAL ANSWER Concentration and fossil fuel CO 2 emissions have increased greatly since pre-industrial periods because of human action. To mitigate the human impact, the Governments have set up an international climate change policy.  1979: First World Climate Conference  1992: “Earth Summit” in Rio  1997: Kyoto Protocol (binding agreement reached on emissions reductions for developed countries)  2005: Kyoto Protocol is implemented, launch of the EU ETS Kyoto protocol sets up tools to reduce CO 2 emissions through market based mechanisms:  Emissions trading (allows countries with an emissions reduction target to trade with other countries)  Joint implementation (JI) and Clean Development Mechanism (CDM): a country with an emissions reduction target can get credit by funding emissions-reducing projects other countries

3. 30/10/2006 THE EU EMISSION TRADING SCHEME : HOW DOES IT WORK? CO2 emissions from European industries have been capped; Each industrial plants has got allowances corresponding to its cap (one allowance = one ton of CO2); The allowances are tradable all around Europe; Every year, industrial installations have the obligation to restitute as many allowances as actual CO2 emissions; Two market periods: 2005-2007 and 2008-2012; Free banking and borrowing during each period; Limited possibilities of banking and borrowing between the two periods.

4. 30/10/2006 MORE THAN 50% OF THE ALLOWANCES TO POWER AND HEATING ACTIVITIES Total : 2.2 billion CO2 (50% of the EU CO2 emissions) 11000 industrial sources Breakdown per countryBreakdown per industry

5. 30/10/2006 THE STRUCTURE OF THE EUROPEAN CO2 MARKET Directive 2003/87/EC established a scheme for greenhouse gas emissions allowance trading (1rst period 2005-2007) in Europe.

6. 30/10/2006 A GROWING LIQUIDITY FOR THE EU ETS A very important growth of the OTC market between 2004 (10Mt) 2005 (250Mt) and 2006 (800Mt). 50 to 80 counterparties negotiate regularly on the market (source : Fortis Bank) Share between Exchanges and OTC market : 60/40 Share between Futures and. Spot Markets : 90/10 Share of Powernext : 60% among European spot CO 2 Exchanges Record volume in October 2006 : around 3Mt on Powernext Carbon

7. 30/10/2006 WHAT WE HAVE LEARNT: 4 MAIN MARKET DRIVERS  Temperature and rainfall Long term Short term  Economic growth  Energy relative prices  Level of carbon constraint

8. 30/10/2006 CO2 PRICE : THE CORNERSTONE OF THE ENERGY PRICES (1/2) A strong correlation between CO 2 and power prices. With 65% of its CO 2 emissions produced by the combustion of fossil fuels, the European power generation sector is the largest emitter and is allocated about 30% of the allowances. Consequently, the power producers add to the production cost of the fuels the price of the allowance multiplied by the quantity of CO 2 emitted per MWh generated.

9. 30/10/2006 CO2 PRICE : THE CORNERSTONE OF THE ENERGY PRICES (2/2) Power generation plants are managed on the basis of “spreads”, which represent their operating cash flow calculated as the difference between the selling price of electricity during peak hours and the price of the fuel used, weighted by the energy output of the power plant.  If a power plant burns natural gas, the spread is called the “spark spread”,  And if it burns coal, the spread is called the “dark spread”. All other things being equal, the higher the price of carbon dioxide, the more the operators have an incentive to switch from the power plants with the highest emissions to those that produce fewer emissions.

10. 30/10/2006 THE 2005 DIFFERENCE BETWEEN EMISSIONS & ALLOWANCES Sum of shorts 179,4 Mt [ 9,1% ] Sum of longs 254,0 Mt [ 12,9% ] Net 74,6Mt [ 3,8% ] Millions tons – CO2 EUAs 0100200-100 -200

11. 30/10/2006 SUMMARY ON EU ETS A significant technical and political achievement  The only real CO2 market, emerging standard for carbon credits;  Easily the most important global climate policy development;  A price on 10% of global emissions. A multinational emissions trading system  25 sovereign nations of widely differing circumstances and commitments to climate policy;  Successful allocation of common burden among EU15 and between EU15 and 10 accession states of Eastern Europe. Global implications  An example for others;  A “fact on the ground” in global climate negotiations;  Creating predisposition to and interest in CO2 trading in China, India, Brazil and others.
