The authors acknowledge the contributions by the chairmen and participants of the two meetings where first results of the research and a draft of this report were discussed: • First, the Industrial Council Meeting, 1st September 2011 in Brussels, chaired by Ronnie Belmans, where the robustness of the preliminary results was tested (Annex 3), with special thanks to the expert panel consisting of the invited experts Inge Bernaerts, Isabel Apolinário and Benoît Esnault as well as project advisors Dörte Fouquet and Nils-Henrik von der Fehr. The authors also thank members of the Industrial Council that contributed to this meeting: José Arceluz, Bart Boesmans, Nicolas Beaulaton, Christophe Bonnery, Magnus Callavik, Federico D’Alberti, Peter De Laet, Olivier Despouys, Pascale Fonck, Uros Gabrijel, Georges Fabian, Eric Ghekiere, Fernando Lasheras, Carole Le-Henaff, Robert Maaskant, Geert Magerman, Manel Martinez, Francois Meslier, Guillano Monnitza, Christian Neus, Mats Nilsson, Marie- Anne Plagnet, Jozef Sannen, André Sarens, Friedrich Schwarzlaender, and Peter von Meirhaeghe. • Second, the Scientific Council Meeting, 19th October 2011 in Brussels, chaired by William D’haeseleer, where a first draft of the report was discussed (Annex 4). The authors thank members of the Scientific Council that contributed to this meeting: Ronnie Belmans, William D’haeseleer, Ottmar Edenhofer, Dörte Fouquet, Serge Galant, Jean-Michel Glachant, Peter Kaderjak, François Lévêque, Wladyslaw Mielczarski, Peter Mombaur, Eduardo de Oliveira Fernandes, Ignacio Pérez-Arriaga, Pippo Ranci, Nils-Henrik von der Fehr, and Jorge Vasconcelos. The authors also thank Serge Galant for organizing the Public Consultation (November 01-25, 2011), and ac- knowledge the contributions by consultation respondents (Annex 5). Special thanks go to Ignacio Pérez-Arriaga, who took time out of the pressing agenda to read several drafts of our report, to answer our requests, and to discuss various issues. We are deeply indebted to his unreserved sup- port all along the project.
