ClientEarth warns that hazardous substances remain in widespread use due to rare inspections and lack of sanctions for non-compliance. The European Chemicals Agency reported significant compliance failures among companies, particularly with carcinogenic substances like chromium trioxide. The report highlights a systemic failure of oversight and a 'sense of impunity' among companies, with the European Commission criticized for not enforcing regulations effectively. ECHA acknowledges the issues but emphasizes that enforcement is the responsibility of EU governments. The REACH system has faced ongoing controversy regarding compliance and data accuracy.
