*The Power Scorecard reflects the collective exercise of expert judgement by the sponsoring organizations, based on its interpretation of available data and assessment of its accuracy and reliability, and application of state-of-the-art techniques in the identification and quantification of environmental impacts of electric power generation technologies. The Power Scorecard ratings appearing on this website may be based on assumptions made by the sponsoring organizations as to the composition, fuel sources, technologies, and associated environmental attributes of particular products where such information is unknown to or has not been provided by the supplier, and where such information is not publicly available. However, every effort is made to validate the information used in rating products with supplier.
