Environmental law is only effective if people comply with it. In order to improve compliance assurance of (European) environmental law, an action plan has been adopted at European level. Studies show that compliance with environmental law must also be improved in Germany. Following-up on these ideas, the Ecologic Institute, in cooperation with its partners (GAF AG and Dr. Aron Buzogány), puts them into practice in the project "Legal and technical review of selected questions of compliance assurance at European and national level".
