The National Green Pages™ is a directory listing nearly 3,000 businesses that have made firm commitments to sustainable, socially just principles, including the support of sweatshop-free labor, organic farms, fair trade, and cruelty-free products. Companies who join as members may display the Seal of Approval.

To be listed, companies must pass Green America's screening process, and commit to fair treatment of their employees and workers in their supply chain, to promoting healthy communities where they do business, to preserving the environment, and to delivering quality products to their consumers. The Screening Committee, which is appointed by and reports to Green America's board of directors, investigates each applying company to determine its familiarity with and commitment to social and environmental responsibility, and looks for significant evidence of this commitment in the practices and policies of the company. 

To qualify to appear in the National Green Pages™ and carry the Seal of Approval, companies' representatives must demonstrate that they: - Actively use their businesses as tools for positive social change; - Run "values-driven" enterprises that operate according to principles of social justice and environmental sustainability;- Are socially and environmentally responsible in the way they source, manufacture, and market their products and run their offices and factories; and- Are committed to developing and employing extraordinary practices that benefit workers, customers, communities, and the environment.
