Widespread agreement exists that environmentally sound technologies should be transferred from developed to developing countries as part of a strategy for addressing climate change. This transfer, in theory, allows developing countries to focus on economic growth and poverty eradication in a way that prevents their emissions trajectories from being as greenhouse gas intensive as developed country ones have been. This chapter contributes to the dialogue over appropriate legal approaches to climate change technology transfer by providing a law and geography analysis of the technology itself and the way in which it is transferred. It argues that effective technology transfer requires a nuanced analysis of what should be considered environmentally sound and how the transfer can be accomplished effectively. Using the example of technology needs assessment, the chapter argues that more fluid governance models have the potential to help assist in framing appropriate transfers.
