While environmental concerns have recently taken a backseat to the economic and financial crisis, scientific projections on climate change continue to call for action. Yet, international cooperation has been hampered and a rift between developed and developing nations is increasingly evident. Companies from developed countries are interested in recouping their investments in clean energy technology through property rights; developing nations contend, however, that such technology must be made available to all nations. This Policy Report, featuring essays from Robert Percival and Miranda Schreurs, examines American and German views on this contentious issue, focusing on what roles technology transfer and intellectual property rights play in the climate policy debate.
