The European Commission has released Survey on Open Access in FP7
Here's an excerpt:
In May 2011, the Commission identified the 811 projects designated at the time with Special Clause 39 in their grant agreement and sent a questionnaire to all project coordinators in order to collect feedback on experiences of both the implementation of the pilot and the reimbursement of open access publishing costs. The objective was to provide input for the future of the open access policy and practices in Horizon 2020, which is the future EU framework programme for research and innovation, and for the preparation of a communication from the Commission and a recommendation to Member States on scientific publications in the digital age.
The online questionnaire was open between 29 June and 26 August 2011 and enabled the collection of a total of 194 responses (success rate: 24 %). Many respondents used the possibility to answer ‘no opinion’ to some questions, but this constitutes valuable information. The final report was prepared in October/November 2011. Annexes include tables of statistical results in each FP7 research area.
