Unless the event is dedicated to being green continuously then I think it's a wasted effort just like the Academy Awards going carbon neutral and using hybrids for the year An Inconvenient Truth won. IMO, it feels like a media stunt. Are the Oscars still carbon neutral each year? Do they still use hybrids? I have no respect when events promote themselves as being green but it only happens that one time. It completely sends the wrong message that we need sustainability and environmental responsibility CONTINUOUSLY!
