The objective of the book is to explain the EU's climate policies without the jargon, and to demonstrate the step-by-step approach that has been used to develop these policies and the ways in which they have been tested and further improved in the light of experience. The book shows that there is no single policy instrument that can bring down greenhouse gas emissions, but the challenge has been to put a jigsaw of policy instruments together that is coherent, delivers emissions reductions, and is cost-effective. Set against the backdrop of the 2015 UN Climate Change conference in Paris, this accessible volume will be of great relevance to students, scholars and policy makers alike.
