Hope that works.
|Good find Ross,
I interviewed the creator of this website a year or so ago, she admitted she was quite busy and had a hard time keeping it up to date.
Some of the more active sites are:
The Broadway Green Alliance
and the best general source I have found is the CSPA, or Center for Sustainable Practice in the Arts
Also of note is the stuff at the Arcola Theatre in London UK
Also what the London Green plan is all about
FYI there is a new Sustainability Commission in CITT ythat will be launched at the 2012 conference
