While much of the responsibility for driving climate change solutions that address the needs of the poorest and most vulnerable rests with governments, it has become increasingly clear that businesses will be an essential partner in preparing for and responding to the impacts of a changing climate and in building a global green economy. Developed in collaboration with Oxfam International, the World Resources Institute and the United Nations Environment Programme, this publication aims to support the efforts leading up to Rio+20, as well as the activities, processes, commitments and partnerships that flow from it. By highlighting the nexus among climate change risks and opportunities, sustainable development and climate change adaptation, this book provides useful guidance to business leaders and policymakers alike.
