The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 75-76).This thesis contrasts the quantification of avoided emission benefits of renewable generation as determined by a marginal emissions analysis and the methodology specified by the Massachusetts Greenhouse Gas Policy and Protocol. Both methodologies are applied to an offshore wind installation that is currently being proposed by the Town of Hull, Massachusetts. The key finding is that the Massachusetts Greenhouse Gas Policy undercounts the avoided emissions benefits of the proposed installation by a range of 30%-50%, depending on the emission. Finally, the policy implications of this finding is explored and expounded upon.Tarek Rached.S.M
