At the beginning of the 1990s the CAs raised the question how to check the provisions for new chemicals introduced in the 7th amendment of the dangerous substances Directive. The work was started with an inspection manual developed by an European working group (a sub-group of the CAs) to assist the enforcement authorities. After that, the CAs started with three enforcement inspection projects; after these projects were completed, the representatives of the CAs agreed upon the need for a network. So the informal network CLEEN was established during a CA Conference in Athens in 2000.

In the Regulation 1907/2006/EC (REACH), a Forum for Exchange of Information on Enforcement is foreseen as part of the European Chemicals Agency. This Forum shall coordinate a network of Member States authorities responsible for enforcement of the REACH Regulation. The tasks of the Forum will be essentially a continuation of some undertaken currently by the informal CLEEN network, therefore the experience of the CLEEN gained in the last 10 years will be useful for the activity of the Forum.
