Technology and U.S. Emissions reductions goals: Results of the EMF 24 modeling exercise

Abstract

This paper presents an overview of the study design and the results of the EMF 24 U.S. Technology Scenarios. The EMF 24 U.S. Technology Scenarios engaged nine top energy-Environment-Economy models to examine the implications of technological improvements and technological availability for reducing U.S. greenhouse gas emissions by 50% and 80% by 2050. The study confirms that mitigation at the 50% or 80% level will require a dramatic transformation of the energy system over the next 40 years. The study also corroborates the result of previous studies that there is a large variation among models in terms of which energy strategy is considered most cost-Effective. Technology assumptions are found to have a large influence on carbon prices and economic costs of mitigation. © 2014 by the IAEE. All rights reserved.
