Book excerpt: This second and fully revised edition brings together some of the most influential work on the theory and practice of contemporary EU environmental policy. Comprising five comprehensive parts, it includes in-depth case studies of contemporary policy issues such as climate change, genetically modified organisms and trans-Atlantic relations, as well as an assessment of how well the EU is responding to new challenges such as enlargement, environmental policy integration and sustainability. The book's aim is to look forward and ask whether the EU is prepared or even able to respond to the 'new' governance challenges posed by the perceived need to use 'new' policy instruments and processes to 'mainstream' environmental thinking in all EU policy sectors.
