Its obviously EU - so not the UK, or Norway or Switzerland or Russia...
I agree it is Eu-wide or pan-EU rather than pan European.
Its probably not going to solve the problems it sets out to given all the differences between EU countries legal systems, tax, regulation etc.
EEA applicability might be less obvious than you imply however.
It's not obvious to me at all, that's why I asked, precisely because of the use of "pan-European".
