I've been working mainly on LEED projects outside the US (AUS+DK). I'm afraid I have to say we have met numerous problems not directly connected to the level of Energy and Environmental Design quality requirement but related to the LEED national approach.
Numerous future sustainable building ratings will occur outside the US, and if the USGBC does not take that soon into consideration, the owners, builders and consultants will start (or continue) using other rating systems.
More and more clients ask us which sustainable building rating system should they go for. And it seems, that LEED is the only one that has not started to work more locally.
LEED needs to be adapted for each country / region and not just through regional priorities. I advise acutely the USGBC to work more closely with the other national GBC or local partners.
