Women in Europe for a Common Future, (WECF) founded in the Netherlands in 1994, " is a network of 100 member organizations and individual members who share a common concern to promote a healthy environment for all, strengthen the role of women and promote a gender and rights based approach in environment and sustainable development policy and implementation." Recently, WECF issued a position paper, "Nano: The Great Unknown". WECF takes the position that "Neither the industry nor public authorities have shown adequate leadership and willingness in addressing" the possible toxic effects of manufactured nanomaterials (MNMs) on humans and the environment.

After briefly surveying European Union (EU) and non-EU regulatory efforts and finding them all lacking, the WECF calls for applying the precautionary principle and the principle of "no data, no market" for all nanomaterials and products containing nanomaterials.

WECF demands that full information about possible risks of nanoparticles as well as access to information on which products contain nanomaterials should be provided to the public, including developing countries) without delay.

The position paper then presents seven additional demands or "actions" by WECF:

1- "WECF demands that manufactured nanomaterials are treated as totally new substances."

2- " WECF demands the application of "no data, no market" – and in the case of REACH, this is to be independent of tonnage. Registration of nanomaterials under the corresponding bulk chemical should by default be prohibited."

3- "Nanosubstances should be subject to a far reaching health assessment (health, environment)."

4- "WECF asks decision-makers …
