Some Member States (for instance, Estonia and Hungary) even require sending copies of all Annex VII documents to the competent authorities, but the countries considered in this project-Denmark, Finland, Norway, and Sweden - do not. Because the companies arrange the shipments between themselves and the authorities are not automatically involved, it can be stated that the control of shipments of green-listed waste is not very strict. On account of this low level of control, the fact that interpreting the regulations requires some experience, and the fact that several kinds of operators are active in the waste business, there is a risk that not all shipments described as shipments of green-listed waste take place "by the book". It might be that some waste requiring a notification is shipped as green-listed or that waste is shipped in contravention of an export ban.
