Strategic research and innovation agenda The proposed European Partnership for Clean Aviation Draft - Version July 2020 Courtesy of DLR STRATEGIC RESEARCH AND INNOVATION AGENDA Foreword Substantial amounts of information contained within this document originate from before the coronavirus crisis Information and figures, data and forecasts included in this document originate from before the coronavirus-re- lated crisis. It is much too early to understand the full impact of the coronavirus-related crisis on short and mid- term traffic. However, it is clear that this crisis calls for even more action from the European Union institutions on green innovation and in support of the aviation sector’s transformation than there has been to date. • The need and challenge of tackling climate change is an unrelenting priority. • Connectivity and mobility are essential to humanity. While we believe the long-term need for connectivity and mobility will remain strong, and demand for aviation will recover, the short- to medium-term will be significantly impacted. • The capability of the sector to self-finance is rapidly eroding due to the severity of the economic and finan- cial emergency that is propelling the aviation and aeronautics industries into an unprecedented crisis. • For Europe to maintain a leading role in aviation its industry needs a level playing field. On the worldwide stage other economic powers such as the US and China are heavily supporting their sectors with R&I. The US has recently announced a significant stimulus package for the aeronautics industry going well beyond previous levels of R&I support and tax breaks. China’s capacity to invest is comparable. There is a significant risk of losing jobs, intellectual property and activity if Europe does not invest proportionately and protect its sovereign capability. • For the EU political agenda, the success of the Green Deal in aviation depends on the European aeronaut- ics industry’s ability to keep its rank on the worldwide stage through its capacity to export its aircraft and European technologies. Making smart use of the recovery programmes being prepared in terms of accelerating the technology tran- sition to a new, sustainable aviation system with green aircraft, engines and systems can position the Euro- pean aviation and aeronautics sectors to take a commanding leadership role in a globally strategic value chain, ensure critical capabilities and set new global standards in sustainability.
