This project period was from March 2009 to December 2009, and the budget was allocated at the total amount of 2500K NTD. The mission of this project supported by the Office of Sustainable Development, Environmental Protection Administration (EPA) Taiwan, was to gather current important international information regarding the broad environmental, health, and safety (EHS) issues on nanotechnology, thus to provide dialogue platform for various stakeholders. It was expected that through this dialogue mechanism to reach perception risk study, good practice management and law and policy management for nanotechnology development. In 2009, the project working group consolidated the already functions of Environmental Nanotechnology Knowledge Platform (ENKP) and spread it to the general public. The revised website started operation on August 2009, and added another 8 target information sources for ENKP. These information sources were proposed by the project working group in a written report “The Current Status of The Nanotechnology EHS Database Worldwide”. The information sources were further confirmed by the experts’ panel in a workshop and have been adopted in the ENKP web-spider. Based on the implement of ENKP and results from the information source confirmation workshop, the project working group raised three issues in the ENKP for general stakeholder to discuss, these issues are: perception risk study, good practice management, and law and policy management. It was expected that the output of the discussion result may serve as policy recommendation for government. The project working group also assembled a one-day “Environmental Nanotechnology Forum 2009” with more than 140 registered and 10 lectures articles in a collected publication. The themes of the forum centered on nanotechnology of environmental challenge and towards sustainable development. Some lectures in the forum came from the 2009 EPA Taiwan funded nanotechnology related projects. It was expected that through the forum the general stakeholder on Taiwan can share and exchange the research result, thus to promote the science and technology research. The project working group also proposed “Taiwan’s Strategic Plan for Responsible Nanotechnology (2009-2014)” on the basis of the 2008 position paper of Taiwan EPA, and organized two workshops to expend the governmental position to international society.
