This third annual edition of "Climate Action" focuses on some of the major issues for resolution in Copenhagen and the actors who can help to implement the solutions. Progress will require commitment and cooperation. Partnerships will be central, both in Copenhagen and beyond. Climate Action is produced to encourage and assist governments and business to lower greenhouse gas (GHG) emissions. This book features a range of articles that encourage the sharing of best practice and the development of new technologies and initiatives and illustrates the opportunities for business and governments to reduce costs and increase profits while tackling climate change. The articles cover human impact, policy, business and finance, technology, energy, transport, ecosystem services, built environment and a regional focus on Canada.
