On June 13, 2013, the Organization for Economic Cooperation and Development (OECD) Working Party on Nanotechnology (WPN) published the final report Nanotechnology for Green Innovation. The report summarizes information collected from various projects undertaken by the WPN regarding the use of nanotechnology for green innovation. It also draws on results and conclusions from the March 2012 symposium on “Assessing the Economic Impact of Nanotechnology,” which was organized by the OECD WPN and the U.S. National Nanotechnology Initiative. The report focuses on an introduction to “green nanotechnology,” strategies for green innovation through nanotechnology, and the impacts of green nanotechnology. The report also highlights investments in nanotechnology, priorities of selected countries, and opportunities for public-private collaboration.
