Schedule & Milestones

Clean Sky 2 goes live

The Regulation creating Clean Sky 2 (CS2) came into force on 26 June 2014 following its adoption by the Council of the European Union (the EU member state governments) on 6 May 2014. It will build on, and carry forward, the successes of the first period of the Clean Sky Joint Technology Initiative which ends in 2017. The programme’s principal objectives include reducing aircraft emissions (CO2 and NOx), cutting perceived noise levels, and keeping the European aviation and aeronautics sector as a recognised global centre of excellence.

CS2 will run from 2014 to 2024. The transition from the first period of Clean Sky will be effected in 2014 and be completed by 2016.

In recognition of Clean Sky’s achievements to date and its future potential, CS2 will have a bigger budget: just over €4 billion compared to the €1.6 billion earmarked for its predecessor. It is also committed to build individual Clean Sky research and innovation projects into demonstration platforms and products close to market-ready levels.
