In December 2015 the European Commission launched a targeted consultation on the long-term sustainability of pan-European Research Infrastructures. The purpose of this consultation was to identify trends and possible corresponding actions that could be implemented at regional, national and European level, to strengthen the long-term sustainability of Research Infrastructures. The results of the consultation are presented in this report and highlight the need to strengthen the involvement of industry to develop credible business models as well as efficient governance models to develop research infrastructures. It is also necessary to look into the different existing funding schemes both to ensure appropriate synergies and to explore possible new solutions.
