This article shows just how far we have to go:
It is correct that people may become complacent just because they use eco-products and eco-machines, and buy local, but these may not be all they seem. We don’t want to put people off making improvements because it seems too complicated to know what is best and this seems an argument for proper research with clear recommendations for major effective changes. David MacKay’s book Sustainable Energy – without the hot air makes similar points.
There is a temptation for manufacturers of good products to make eco/sustainable claims that are only partially true in order to enhance sales.
