This project was started 2008/5 till 2008/12, and the budget was allocated at the total amount of 3500K NTD. The mission of this project supported by the Office of Sustainable Development, Environmental Protection Administration (EPA) Taiwan, is 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 strengthen EPA policy quality. The project working group has constructed a Web 2.0 based knowledge platform website, named as Environmental Nanotechnology Knowledge Platform (ENKP). The address of the website was located at http://sta.epa.gov.tw/portal_sgs/, which started operating on 2008/10, includes more than 480 reference articles ranging from the related government reports, governmental (mainly EPA Taiwan) funded project reports, latest original journal articles or research news recommended from the experts, and output effort of this project. Currently there are 21 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 three workshops 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 has raised three important issues for stakeholders to discuss in three workshops including: green nanotechnology, the current research status of USEPA on the environmental nanotechnology of health effect, the societal implication of nanotechnology-european perspective. The project working group also raised three issues in the ENKP for general stakeholder to discuss, these issues are: perception risk study, good practice management, 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 2008” with more than 110 registered island wide and 10 lectures articles in a collected publication. The themes of the forum centered on nanotechnology of environmental risks and towards sustainable development. Some lectures in the forum came from the 2008 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 “The EPA Taiwan Strategy Towards Responsible Nanotechnology (2009~2014)” on the basis of the position paper of EPA Taiwan 2007, and organized two workshops to expend the governmental position to international society.
