Increasing demand for energy consumption leads to concerns of global Greenhouse Gas (GHG) emissions. Most of the supplied energy comes from dirty generating units. Since there are no regulations to limit emissions of CO2 from electricity generation, power plants can emit unlimited amount of CO2. This dissertation, first, aims to explain some government directed plans to reduce GHG emissions. It gives an overview about the Clean Power Plan (CPP) and its benefits and challenges. Further, it explains several options of CPP in reducing emissions and its repeal. Further, this dissertation, discusses the Climate Action Plan (CAP) corresponding to Fort Collins, Colorado, U.S. and its timeline targets.Demand side management (DSM) is discussed as a solution from engineering practices to affect GHG.Several options from DSM are investigated to reduce emissions. In fact, reducing energy consumption through DSM leads to a reduction in harmful emissions to the environment. This dissertation aims to identify the best available DSM options that will make the biggest difference for GHG reductions.A framework is created to examine several options of DSM in reducing carbon footprints. The framework states that affecting GHG in electric power system is the main goal. The goal can be achieved by implementing DSM technologies in distribution systems. The framework proposes criteria such as cost, power quality, reliability, environmental collateral, and socioeconomic equity to examine the effectiveness of several alternatives: energy management, communication and intelligence, electrification of heating and transportation, and distributed generation.Multi-Criteria Decision Making (MCDM) algorithms have been proposed to prioritize alternatives and select the ones that achieve suitable emissions reduction. Analytic Hierarchy Process (AHP) is one of the most common tools to perform decision-making analysis. The findings from AHP show that the "communication and intelligence" option is the potential optimal alternative in achieving the goal. Analytic Network Process iii (ANP) is another method for making decisions. It provides feedback and interdependence relationships between all nodes of the problem. It is more realistic and accurate than AHP. The results obtained from ANP suggest that "communication and intelligence" is the optimum technology to reach the target. By using ANP, the overall priority ranking has changed and the difference in priorities has reduced.Institute of Electrical and Electronics Engineers (IEEE) 13-node test feeder is used, through Open Distribution System Simulator (OpenDSS), to perform power flow analysis on yearly load profile corresponding to Fort Collins, Colorado, U.S. The analysis includes simulation for several scenarios from the MCDM alternatives, either individual alternatives or mixed alternatives. The obtained results for the base case show the emissions decreased by 16.26% from 2005 level which comply with the results from emissions indicator released by the city. Integrating the MCDM alternatives indi...
