A trial of the UK's voluntary reporting scheme for engineered nanomaterials was carried out between September 2006 and September 2008. DEFRA received 13 submissions to the scheme during this period. Although the scheme has now officially closed submissions are still accepted.
As stated in the Government's June 2009 response to the Royal Commission for Environmental Pollution's December 2008 Report “Novel Materials in the Environment: The Case of Nanotechnology”, we recognise that, given increasing interest in this area, additional work to boost our understanding is required. Work is currently ongoing to define in more detail how any successor to the voluntary reporting scheme could effectively be introduced, including whether or not it should be mandatory.
