Enforcing the EU F-Gas Regulation, what can Member States do?

This paper explores the tools that Member States have, or can create, in the context of the EU-F-Gas Regulation. The legal base of the EU F-Gas regulation is article 191(1) of the Treaty on the Functioning of the European Union. It therefore leaves it to Member States to take additional measures as long as they do not interfere with the fundamental principles of the European Union, in particular, the free circulation of goods and persons.
