Montreal, 30 June 2021 – New Airports Council International (ACI) World forecasts for the global airport sector show that approximately $2.4 trillion (figures in US Dollars) in airport total capital investments will be needed to address the long-term trend in passenger demand to 2040. The Global Outlook of Airport Capital Expenditure – Meeting Sustainable Development Goals and Future Air Travel Demand, published today, shows that significant investment in new greenfield airports, as well as significant investment to expand and maintain existing airport infrastructure, is required. The study was supported by Hamad International Airport and developed in collaboration with Oxford Economics.
