Answer given by Mrs Reding on behalf of the Commission
The Commission refers to Acrobat Reader as the proposed tool for reading PDF files under the tab ‘Technical questions’(1) in the Frequently Asked Questions section of the interinstitutional Europa portal. Occasionally, other pages on the Commission website refer to this tool. In total, there are less than ten references to Acrobat Reader.
The Commission has no information about references to proprietary PDF readers appearing on websites of other EU institutions and has no competence for issuing guidelines for public sector websites in Member States.
