This study firstly evaluates the objectives and strategies of United Nations Sustainable Development Goals (SDGs) to build the relationship between green chemistry 12 principles and circular economy. Based on the definition of green chemistry 12 principles and the concept of circular economy, the related polices and strategies from the United States, the European Union, Canada, the United Kingdom, Germany, Sweden, Netherlands, Japan, Republic of Korea and China were reviewed. The international movement on developing trend of green chemistry, chemical substance management, policy implementation, innovative technologies and integrated promoting strategies on green chemistry was also analyzed. In addition, the policy goals and projects related to green chemistry and circular economy for domestic government agencies including Environmental Protection Administration, Industry Bureau, Energy Bureau, Health and Welfare Department, Ministry of Labor, the Council of Agriculture, the Department of Health and Welfare and the Ministry of Finance were also analyzed and reviewed. To investigate the policy strategies and solution for green chemistry and circular economy, we also invited related experts from government, industries and academy to hold Ad Hoc committees. Moreover, we also conducted four sustainable green chemistry lectures to emplyees of Environmental Protection Administration and students of National Taiwan University, which can promote the educational propaganda of green chemistry and circular economy concept in various field. Finally, the proposed strategies and priorities governance direction (PGD) for implementing green chemistry 12 principles toward circular economy were suggested: (1) to integrate green chemistry 12 principles towards Prevention, Assurance, and Sustainability (PAS) strategies thereby promoting sustainable green chemistry development and a circular economy system; (2) to develop green engineering and green chemistry educational program both in the industry and university; (3) to conduct the developing strategies and action plans on innovative green chemistry technologies; (4) to facilitate the policy implementation on green chemistry 12 principles including use of alternative chemicals, redesign of chemical process and reduction of energy and resources consumption theregy gradually building a completed circular economy system.
