Launched to tie-in with the United Nations Climate Change Summit in Copenhagen (COP15), Dr Steffen Bohm and Siddhartha Dabhi's new book, Upsetting the Offset: The Political Economy of Carbon Markets, challenges the environmental claims made about carbon markets and carbon offsetting schemes. The book - which collates contributions from more than 30 leading experts - is another voice in the growing criticism about the business of carbon and how it has failed to deliver promised reductions in greenhouse gases. The book contributes to a growing field of critics of carbon markets by highlighting several up-to-date examples of where the system has failed and often led to negative social, economic and environmental impacts in deprived countries. http: //mayflybooks.org/wp-content/uploads/2010/07/9781906948078UpsettingtheOffset.pdf"
