In the face of stark disagreement about the politics of climate change, no-one argues against the benefits of cleaner, greener products. A green revolution seems to have been underway in supermarkets and households as people try to make a difference and reward green companies. But peek behind the advertising funded by the world's greenest brands and corporations and the 'green revolution' starts to look more like greenwash - masking 'business as usual'.
Beneath the seductive branding and spin lies an uncomfortable possibility - that the revolution may be an illusion, and that the biggest marketers of climate-friendly products and brands might be making things worse not better.
