The IEA carries out a comprehensive programme of energy co-operation among its member countries, each of which is obliged to hold oil stocks equivalent to 90 days of its net imports. The PEPDEE work is being undertaken by the IEA as a contribution to a Task Group within the International Partnership on Energy Efficiency Cooperation (IPEEC). Financial and in-kind support for the lEA's contribution to the PEPDEE work programme comes from UK DECC, the US Department of Energy, the Australian Department of Climate Change and Energy Efficiency (DCCEE), and the European Commission's Directorate General of Energy (DG-Energy).
