In the five years since its launch, the Clean Energy Transitions Programme (CETP) has become the largest and most important programme at the International Energy Agency (IEA). It has been the main vehicle through which the IEA has established, deepened and strengthened partnerships with major nonmember countries – those countries that are at the forefront of the clean energy transition. The programme has also played a crucial role in enabling the IEA to strengthen its global leadership role in clean energy transitions at a pace and scale that would otherwise not have been possible, with great benefit to the programme’s focus countries and IEA member countries alike. This CETP Annual Report 2022 provides an overview of the programme’s major achievements in the last year. During this time, the CETP has driven forward an ambitious and impactful agenda, even as the world has contended with multiple overlapping crises.
