Following yesterday’s piece on ‘insert green credential here releases’, have you ever looked at an advert with more than a little skepticism about its green claims? Adverts such as oil firms stating everything except they produce oil etc. have a habit of getting Greenbang slightly annoyed.

To highlight these a greenwash index web site has been created. Linking into YouTube it asks its visitors to rank adverts on how believable the claim actually is, ranking the commercials from 1 (green) to 5 (so freshly greenwashed you can still see the oil seeping down the wall).

The personal favourite is ranked at 4.85. The advert promotes states Coal: clean, green energy. Hmmm
