International Energy Agency The International Energy Agency (IEA) acts as energy policy advisor to 27
member countries. Founded 1974 – energy securitygy y IEA’s mandate has broadened to incorporate energy security, economic
development and environmental protection. Current work focuses on climate change policies, market reform, energy g p , , gy
technology collaboration and outreach to the rest of the world, especially major consumers and producers of energy like China, India, Russia and the OPEC countries.
E t bli h d “I l ti A t ” i hi h t b Established “Implementing Agreements” in which two or more member states agree to co-operate or exchange information on specific topics
Today there are 41 IAs covering full range of energy supply and demand issuesissues
Most are task sharing, a few are cost sharing in which members subscribe to maintain staff to undertake programmes of work determined by the members
One of these is IEA Greenhouse Gas R&D Programme (IEA GHG)

Role of CCS in climate change mitigation?Role of CCS in climate change mitigation?• IPCC Special Report (2005) – CCS contributing 15-55% of CO2
mitigation to 2100
• IEA Technology Perspectives (2006) – CCS 20-28% of mitigation to 2050. Second only to energy efficiency.
• Stern Report (2006) – CCS ~10% mitigation by 2025, ~20% by 2050. Marginal mitigation costs without CCS increase by ~60%.
• EC/Shell (2007) - 7 yrs delay CCS = 90GT CO2 to 2050 = 3 yrs global emissions = 10ppm
