I’ll just quote the source:
The term greenwashing applies when companies (or governments) spend more money or time advertising being green, than on investing in environmentally sound practices.
In business, greenwashing often means changing the name and/or label. Early warning signs that a product is probably toxic include images of trees, birds, or dew drops. If all three are on the box, the product will probably make your skin peel off in seconds…
Thanks to John Thackara at Doors of Perception, and to One Plus One Equals Three for the pointer.
