The European Commission launched on 29 October 2003 its proposal for a new chemical legislation con-cerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH). In August 2004 the Nordic Council of Ministers granted funds to the Nordic Chemicals Group to start a joint Nordic project on "Analysis of the enforcement according to REACH". The objective of the project was to examine, from an enforcement perspective, the main titles (registration, evaluation, authorisation and restrictions) of the Commissions REACH proposal of October 2003 and result in proposals and viewpoints on enforceability of REACH and how REACH will affect today's enforcement including new demands on enforcements authorities, enforcement methods and cooperation between en-forcement authorities and Member States. In brief, REACH means new challenges for enforcement in the Member States. These exercises are compiled and discussed in this report with proposals for further work.
