In the global society eco-innovation emerged as an effort to implement sustainable development as outlined during the 2012 RIO+20 conference. States and firms have established and implemented policies and strategies for eco-innovation as one route to sustainable development. Eco-innovation has been facilitated in developed countries, especially OECD members and European countries through action plans. Recently eco-innovation policies are emerging in the developing countries. Based on this context, this research aims to analyze eco-innovation policies in Asian countries. We investigated policies related to sustainable development in 17 Asian countries with the categories of policy instruments. National policies were interpreted and compared with the classification of development stages according to the World Economic Forum (WEF). As a result this research indicates different approaches to eco-innovation in Asian countries. It offers insights to designing national strategies for eco-innovation in Asia's developing countries. Therefore this research can contribute to facilitating and diffusing eco-innovation toward sustainability in Asia.
