The IEA acts as a policy adviser to its member states, but also works with non-member countries, especially China, India and Russia. The Agency's mandate has broadened to focus on the "3Es" of sound energy policy: energy security, economic development, and environmental protection. The latter has focused on mitigating climate change. The IEA has a broad role in promoting alternate energy sources (including renewable energy), rational energy policies, and multinational energy technology co-operation.
IEA member countries are required to maintain total oil stock levels equivalent to at least 90 days of the previous year's net imports. At the end of July 2009, IEA member countries held a combined stockpile of almost 4300000000 oilbbl of oil.
The Executive Director of the IEA is Nobuo Tanaka. The Deputy Executive Director is Richard Jones.
