'With this book, the Harvard Project on International Climate Agreements provides an excellent analysis of the potential instruments and policies available for a new climate regime. The UN Climate Change Conference in Copenhagen in December 2009 is a decisive moment for our ability to address a global challenge together. As the host of the Conference, Denmark plays a critical role in facilitating a global agreement. This book is a valuable tool for the negotiations.' Lars Løkke Rasmussen, Prime Minister of Denmark and President of the 15th Conference of the Parties of the UN Framework Convention on Climate Change
