Sustainable Strategies & Solutions for Cleaner Air Transport - The vital question for the future of aviation is: how do we tackle greenhouse gas (GHG) emissions from aviation and their serious impact on the climate? There are not many options available. Electric-driven aviation is, for the next decades, only suitable for short distance flights. The use of bio-based kerosene is confronted by NGOs as “putting unacceptable pressures on natural resources, such as forests and land”. It is also hampered by quality and standard issues for different biomass sources and conversion processes. A big hope are aviation fuels based on the utilisation of CO2 and green hydrogen: CO2 as a GHG is not only the problem, it can also be part of the solution. Essential is the capture and reuse of CO2 – meeting the challenge of climate change in aviation requires a circular use of CO2. And fortunately, a global market is waiting for those who are helping the airlines to meet the requirements of the Paris Climate Agreement. If these questions and the sustainability of aviation is your concern, the “1st European Summit on CO2-based Aviation Fuels”, 23 March, 2020, Cologne, Germany, is the event to attend. This summit is for decision makers in politics, organisations, airlines and the respective industries. You are cordially invited by the International Association for Sustainable Aviation (IASA) and nova-Institute to take part in this essential summit. The aviation summit is one day prior to the 8th edition of the established “Conference on Carbon Dioxide as Feedstock for Fuels, Chemistry and Polymers”, 24-25 March, 2020, Cologne, Germany (http://co2-chemistry.eu/). Combined tickets are available.
