Karsten Neuhoff www.electricitypolicy.org.uk\tsec\2 Create clear emission reduction trajectories Define clear (& small) CDM inflow volumes –CDM for diffusion of technologies / removal of barriers Use auction revenue for international cooperation Avoid leakage (emissions moving outside cap) -> Visibility for investment and corporate strategies

15. Karsten Neuhoff www.electricitypolicy.org.uk\tsec\2 Summary leakage Potential issue only for 1-2% of economic activity –Materiality to be assessed on sub-sector level –Relevance only if there will no strong global deal 2009 Instruments exist to avoid leakage – sub-sector by sub-sector –State aid, free allocation, border adjustment –Side effects: lower efficiency / international complications In Europe decide on instrument in 2010/2011 –Focus first on international deal –Cooperate in parallel internationally on instruments to address leakage –Ensure transparent approach – no special provisions in Directive This creates maximum investment security –Industry & environment interest coincide -> we will avoid leakage –Investments that would be viable under global deal remain viable
