International Clean Technology Diffusion: Pathways and Prospects
By Wenting Cheng
International clean technology diffusion is essential to mitigate and adapt to climate change, while fast and optimal diffusion can be prevented by the paywall of patents. This article examines three pathways to foster international clean technology diffusion: through restriction of intellectual property, including imposing external restraints in environmental law; striking an internal balance in maximizing TRIPS flexibilities; and keeping the status quo. It finds that the first two treaty-based pathways may not work, and an operable pathway to promote clean technology diffusion is to maximize and consolidate TRIPS flexibilities in national laws. This option challenges the popular proposal of a “Doha-like” declaration on TRIPS and climate change due to the paralysed multilateral trade mechanism, asymmetrical negotiation power of developing countries, prolonged negotiation process, and categorization problem in treaty negotiations.
