Page 28 Trading activity EUA nThe Dec 2005 delivery contract remains the most liquid market nSpot has started and is increasing as more registries are opened nTraded volumes increased rapidly in January 2005 nLiquidity is still hindered by contractual mismatch nExchanges: emerging but fragmenting market.

Page 29 Impact EUA on the power price  Power sector expected to deliver proportionately far larger reductions than any other sector due to:  average lower marginal reduction cost  cost pass through to customers  1MWh coal powered  0.8 tonne CO 2  1MWh gas powered  0.35 tonnes CO 2

Page 30 EUA price drivers; political environment nPolitical –Local distribution of EUA (natural long/short positions in countries) –“Windfall profit” discussion –Future political decisions? nFuel prices –Reduction of EU emissions by fuel switching possible –Swing in world oil&gas prices drives CO2 volatility –EU emissions prices influence dark-spread/spark-spread, power price nWeather –Hot/Cold, Dry/Wet (Hydro v.s. Fossil), Wind nPsychological price barriers –From time to time the market decouples from fuel prices nWorld-wide worries –Kyoto versus non-Kyoto; biomass discussion; VLT CO2 storage n  Security of supply uncertainties / discussion

Page 31 Climex Proposition nAPX Group is working with New Values to create a European wide pool of liquidity for spot trading of CO 2 nAPX and UKPX linking clearing functions to give participants a “local” counterparty either in the Netherlands or the UK nFast and easy accession to the market nLow cost and flexible solution
