But wait, wait, how do they rate all these products and what is there methodology?

GoodGuide is building a comprehensive source of information on the environmental, social, and health performance of products and companies. The GoodGuide team works with a network of leading academic institutions, government data sources, non-governmental organizations, and private research firms to bring world-class information to consumers. GoodGuide’s scientists have collected data from around the world on chemical ingredients, products, brands, factories, companies, industrial sectors, and even countries. We gather the highest quality data available and convert this information into ratings that can be used by non-scientists to easily evaluate products and companies. In the future, GoodGuide will have tools to let consumers screen this data through their own personal preferences, allowing them to “filter” and search for products and companies that match their specific values.
