This is a great idea! France recently banned fossil fuel ads, so greenhindering is not a wild idea.
I like the comparison to the Bechdel test, which worked to increase the number of female protagonists in films. It makes sense to do the same for green products. For example, maybe the number of electric cars to fossil fueled cars in action movies? (Hint: only the baddies drive gas guzzlers.)
I also think the disposable cup was an apt metaphor by Harvard Review for corporate culture.
