NanoCEO is a volunteer citizen organization in Wisconsin that formed after several of us participated in a Consensus conference on Nanotechnology organized in Madison in the spring of 2005. Our recommendations are summarized in a report available here.
After the consensus conference, we formed a citizens group (the Citizens’ Coalition on Nanotechnology, CCoN) and organized Nano Cafés to engage the community in discussing nanotechnology.
In 2008, we changed our name to the Nanotechnology Citizen Engagement Organization (NanoCEO)and became independent from the University of Wisconsin.
Although many people don't know much about nanotechnology, it has been called the "next Industrial Revolution"--and, in fact, the Nano Revolution is already here. Nanotechnologies and nanomaterials are being used in hundreds of consumer and industrial products in nearly every field. These technologies promise many benefits to society, but also pose many environmental and health risks, as well as ethical and societal issues, often overlooked or downplayed by those promoting them.
Meanwhile, lay citizens have few opportunities to engage in discussions and decisions about these matters, which could have significant consequences on their lives and their communities, as well as on future generations.
In this context, the purpose of NanoCEO is to
(1) Educate citizens and workers from diverse backgrounds about nanotechnology developments and impacts;
(2) Facilitate citizen engagement and societal dialogues about nanotechnology's applications and implications;
(3) Facilitate lay citizens’ and workers’ capacities to address nanotechnology issues on the individual, workplace, community, and political levels.
In addition to gathering information about nanotechnology and making it accessible on this website, we organize events, meetings, and other opportunities for lay citizens to learn about emerging nanotechnologies and to engage with their friends and neighbors, other interested citizens, and policymakers in discussions and decisions about them. To date we have organized numerous successful Nano Cafés throughout the Madison area.
Broader than our Nano Cafes, we also engage in a range of nanotechnology events and policy meetings organized by government agencies and others--where we work to bring our questions, perspectives and recommendations to decisionmakers at community, state, and federal levels.
For example, we participated in the meeting organized by the National Nanotechnology Coordination Office (NNCO) on January 4, 2007 about environmental, health, and safety aspects of nanotechnology.
See our press release: Madison resident's lone citizen voice in the Halls of Washington. You can read Mr. Miller's testimony here (see pgs. 280-284). Also, see the comments CCoN submitted together to the NNCO in 2007 after the January meeting, available here.
In March 2009, we took part in the ICTA/CFS petition for rulemaking requesting EPA to regulate nanoscale silver products as pesticides. See our letter here.
In September 2010, we wrote to the EPA asking that the agency not give "conditional approval" to a nanosilver antimicrobial product until it is thoroughouly tested for its environmental and health effects. See our letter here.
For the last several years we have been advocating for an inventory or registry in Wisconsin to track engineered nanomaterials used or sold in Wisconsin industries and consumer products. You can read more about these efforts here and here.
