The Green Good Housekeeping Seal is an emblem signifying that a product has been reviewed by the scientists at the Good Housekeeping Research Institute, is covered by Good Housekeeping’s limited warranty, and has met Good Housekeeping’s environmental criteria.

Before a product can apply for the Green Good Housekeeping Seal it must be evaluated by the scientists at the Good Housekeeping Research Institute for performance and effectiveness and earn the Good Housekeeping Seal. The Seal represents Good Housekeeping's limited warranty: If the product proves defective within two years of purchase, Good Housekeeping will replace the item or refund its purchase price to the consumer.

Once a product has earned the Good Housekeeping Seal it is evaluated on a wide range of environmental criteria—including ingredient and product safety, reduction of water use in manufacturing, energy efficiency in manufacturing and product use, packaging reduction, greenhouse gas emissions, and the brand's corporate social responsibility. Validation is required for all answers.
