the UK Royal Commission has issued a report on the spread of nano-materials, stating, "Urgent action needed on testing and regulation". In its report, the Commission found no evidence of nano-materials causing harm to health or the environment, but raised concerns that current levels of testing and regulation are inadequate. Consequently, the report calls for REACH to be expanded to make it more suitable for the regulation of nano-materials. This report believes that REACH is a suitable framework for regulation but fails in some aspects specific to nano-materials.

It also highlights REACH's failure to treat nano-scale versions of existing substances as separate entities, despite the potential for them to possess different properties. The report believes that current regulations should be adapted to cover the areas where legislation is currently inadequate to deal with nano-materials. Sir John Lawton, chair of the Commission, said, "We are also concerned that more sophisticated later generation nano-products will raise issues which cannot be dealt with by treating them as chemicals or mixtures of chemicals. Current testing arrangements and existing regulations are inadequate." There are immediate concerns of the report but it also highlights that regulations must evolve as nano-materials develop in coming years.
