ICAO forums provide opportunities for advice and advocacy to be shared with government decision-makers by industry groups, civil society non-governmental organizations (NGOs), and other officially-recognized air transport stakeholders. IAF and ICAO have signed a memorandum of understanding (MoU) that defines the cooperation between the two organizations in relation to the ICAO Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA). Part of this MoU is the realization of capacity building activities, such as the development and delivery of training courses on verification under CORSIA.
