The Clean Sky 2 program in Europe has made strides in transforming the aviation sector for a more sustainable future. Led by the German Aerospace Center (DLR), the program has focused on developing technologies that reduce carbon dioxide emissions, mitigate noise, and enhance European competitiveness. The recent Technology Evaluator report, coordinated by DLR, showcases the significant positive impact of Clean Sky 2 innovations. These technologies have the potential to reduce CO₂ emissions per seat-kilometer by up to 32.5% and cut nitrogen oxide emissions by up to 60%. Furthermore, noise reduction of up to 44% at airports could enhance public acceptance of aviation. The report also emphasizes the importance of progress in hydrogen propulsion, hybridization, and alternative fuels for achieving climate-compatible aviation. Socioeconomic benefits include job creation and a projected 40% increase in value creation in the European aviation industry by 2050. The successful collaboration between research institutions, industry, and policymakers in Europe through Clean Sky 2 serves as a model for addressing climate challenges and ensuring aviation sector competitiveness.
