Silly, and typical of California.
The California State Senate and Assembly passed a bill requiring AEG to make the new stadium 100 percent carbon neutral including the emissions generated from private car trips to and from the stadium.
If they honestly believe their own rhetoric, then the only sensible thing to do would be to pass a bill outlawing the proposed stadium altogether. There is no such thing as "100 percent carbon neutral", and if carbon is the threat that they claim it is, they have no business spending billions of dollars on something as frivolous as another entertainment complex.
