This book brings together the results of two conferences: 'The Kyoto Protocol and beyond: A legal perspective', organised by the University of Siena on 10-11 June 2006, and 'Tackling Climate Change: An appraisal of the Kyoto Protocol and options for the future', held at the T.M.C. Asser Institute in The Hague on 30-31 March 2007. These conferences focused on the legal aspects of the Kyoto Protocol implementation and the post-2012 regime. Experts in European and international environmental law shared ideas and experiences gained so far by the European Union, individual states (including Germany, the Netherlands, the Western Balkans, CIS countries including Russia and developing countries) and private entities in the implementation of the Kyoto Protocol and its flexible mechanisms. Much attention was given to the design of the future regime, from the perspectives of both the European Union and developing states.
