Clean Sky was launched in 2008, following increased recognition of the growth of the aviation sector – an integral and legitimate driver of a more mobile workforce within the global economy - and its bearing on the environment.


European Aeronautics: A Vision for 2020

This report, published in 2001, set out a vision for the European Air Transport System for the next 20 years. It recognised the growing societal pressure to enhance airline passenger capacity and efficiency in an environmentally benign manner, whilst drawing on Europe's leadership in aero-industrial innovation to achieve that vision.

The report also recommended the creation of the Advisory Council for Aeronautics Research in Europe, ACARE, which produced a Strategic Research Agenda (SRA 1) in 2002 built around 5 Challenges for technology development, and a second updated edition (SRA 2) in 2004, which describes 6 High Level Target Concepts and their associated technologies with respect to different socio-economic scenarios. Each Target Concept highlights a particular aspect of the Air Transport System.

Clean Sky works towards meeting two of these Target Concepts:

  • Ultra Green Air Transport System: reducing the impact of air transport on the environment.
  • Highly cost-efficient Air Transport System: through innovative technological developments, Clean Sky will contribute to answering society's needs and securing European leadership in aeronautics.



Since its launch in 2008, the Clean Sky JU has celebrated a number of landmarks and milestones. Explore our timeline below and discover the story of Clean Sky.
