Patterned after the nutrition labels we see on many food products, the social 'nutrition' labels promoted by Project Label (http://projectlabel.org/) are a way to leverage consumer knowledge to provide an idea of what impact a company's products are having on
- personal health, nutrition and safety,
- the social and community level,
- and on a planetary, environmental level.
Each one of these areas is further broken down. How is explained in more detail on this page of the Project Label site.
Project Label is a site in public beta release that provides for consumer input. People can collect and post information in articles. Those articles are subsequently voted on by other consumers. The information which is collected in this way is then processed into the form of a social label. The steps on how this works are described here.
