I had the pleasure of participating at the two conferences which form the basis of this book: as a chairman at the 2007 The Hague Conference 'Tackling Climate Change - An appraisal of the Kyoto Protocol and options for the future' and as a speaker at the 2006 Siena Conference' The Kyoto Protocol and beyond: a legal perspective'. I would like to thank my colleagues Wybe Douma, Leonardo Massai and Massimiliano Montini for those opportunities, and although I was, unfortu nately, unable to contribute a paper to this book due to time constraints, I am glad to be able to say a few words on the issue by means of this foreword. The timing of the two conferences was well chosen: the period between the Siena Conference (June 2006) and The Hague Conference (March 2007) encapsu lated perfectly the period of the drafting, the presentation and the approval of the 'Integrated Energy and Climate Change Package', as presented by the European th Commission on the 10 of January 2007 and as approved by the Spring European th th Council of the 8 and 9 of March 2007. The importance of the Commission's package and the Council's conclusions must be strongly emphasized. They set, at the EU level, legally binding targets regarding the reduction of greenhouse gas of energy, and biofuels.
