A British magazine called Ethical Consumer has firm ideas on what makes for good products.
At their web site, the company says:
Ethical Consumer magazine publishes buyer's guides designed to help you find the products which best fit with your own values.
- Read the truth about the social and environmental records of the companies behind the brands you buy
- Learn about alternative products and support smaller, more ethical companies
I've never seen the magazine, but apparently its September-October 2006 issue includes their special "Ethiscore ethical rating tables for non-dairy milk." The Utne Reader magazine reports that the list includes familiar U.S. brands.
If any British readers find the magazine, let me know what the ratings are. And what an Ethiscore is.
