During the first years of discussions on a draft directive; the document was an item of discussion at each meeting and many comments and proposals were sent to the Commission; i.e. DG XI (now DG Environment). The eighth draft was completed on the 20th of December 1994 as Directive 94/62/EC on Packaging and packaging waste (Ref.1).
The environmental aspects are very important parts of the Directive; and in 1996 the Commission mandated work on Environmental packaging standards to TC 261 and its SC 4.
