Climate change is one of the biggest challenges for mankind. Although there is increasing evidence that climate change is already occurring, there is neither sufficient knowledge as to what extent climate change poses risks to societies and companies, nor about adequate strategies to cope with these risks. Bringing together an international group of scholars from environmental economics, political science and business, this book describes, analyses and evaluates climate change risks and responses of societies and companies. The book contributes to the question of how climate change can be mitigated by discussing efficient and effective design of mitigation measures, in particular emissions trading and clean development mechanism (CDM). Placing special emphasis on the impact of climate change risks on business, the book investigates in which way selected sectors of the economy are affected and what measures they can undertake to adapt to climate change risks.
