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 Joint Undertaking (CSJU) is a successful public-private partnership between the European Commission and the European aeronautics industry that is on the way to achieving its environmental performance targets. The 2nd phase, Clean Sky 2, will build on this success by:

Continuing to integrate breakthrough technologies in aircraft

Demonstrating innovative configurations in aircraft, enabling changes in environmental & economic performance.

Clean Sky 2 technologies will enable future aircraft to:

Cut fuel burn & related CO2 emissions by 20-30%

Cut noise levels (compared to 2014) by a similar amount.

It is also expected to significantly improve competitiveness and mobility in Europe.
