The Electronic Product Environmental Assessment Tool (EPEAT) is a method for consumers to evaluate the effect of a product on the environment. It is assessing lifecycle environmental standards and ranks products as gold, silver or bronze based on a set of environmental performance criteria.

It is managed by the Green Electronics Council, itself a programme of the International Sustainability Development Foundation (ISDF) which ‘envisions a world where commerce, communities and nature thrive in harmony’. To qualify products to the IEEE 1680 family of ‘green electronics’ standards and identify products as EPEAT Bronze, Silver or Gold the organisation has signed an MOU (Memorandum of Understanding) with a group of technical and environmental assessment organisations.

The Council evaluates computing equipment on 51 criteria - 23 required and 28 optional - that measure a product's efficiency and sustainability attributes. Products are rated Gold, Silver, or Bronze, depending on how many optional criteria they meet. On 2007-01-24, President George W. Bush issued Executive Order 13423, which requires all United States Federal agencies to use EPEAT when purchasing computer systems.
