Clean Sky is the largest European research programme developing innovative, cutting-edge technology aimed at reducing CO2, gas emissions and noise levels produced by aircraft. Funded by the EU’s Horizon 2020 programme, Clean Sky contributes to strengthening European aero-industry collaboration, global leadership and competitiveness.
Clean Sky 2's total budget exceeds €4 billion.
Clean Sky's projects are helping to dramatically slash the air industry's CO2, other gases and noise footprints by developing new engine architectures, improved wing aerodynamics, lighter composite structures, smarter trajectories, and more electrical on-board energy.
While some technologies can be assessed during their development phase at component or system level, many key technologies will need to be validated via dedicated test programmes, involving large-scale ground or in-flight demonstration installations: this is the major goal of Clean Sky. These demonstrators integrate several technologies at a major system level or at aircraft level, enabling them to be tested in a relevant operating environment.
