The project aims to increase the pace of airport environmental work and thus become the forerunner of the European regional airport world. The overall objective is to significantly reduce carbon dioxide emissions at SRF airports and enable airlines to refuel fossil-free aviation fuel and recharge electric aircraft as technological developments make it possible. The project will cooperate with at least 120 SMEs that will have the opportunity to develop and reach new markets. The airports will develop a joint and structured way of working on the issues, both in terms of operations and operations at the airports themselves and in terms of the conditions for the airlines responsible for traffic. The project will build new knowledge, disseminate experiences and best practice, as well as plan the implementation of changes that lead to reduced energy consumption and less emissions.
