Abstract: A real-time electricity emissions estimating tool, the Locational Marginal Price Emissions Estimation Method (LEEM), is assessed for its ability to reduce emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), global warming potential measured as carbon dioxide equivalent (CO2e), mercury (Hg), and lead (Pb) on a residential scale. Through LEEM, residential electricity use can be shifted to low emissions times of day. In the study area of Michigan, USA emissions from five types of appliances (hot water heater, refrigerator defrost, dishwasher, clothes washer, and clothes dryer) were calculated to be theoretically reduced by 21–35% annually through a “best-case” application of LEEM. Annual emissions of the five pollutants, SO2, NOx, CO2e, Hg, and Pb, can be reduced across the state by 429,000, 110,000, 87,240,000, 2.21, and 4.53 pounds, respectively – all without a reduction in the electricity used in the period of study. Despite different fuel mixes, similar emissions reductions were calculated for other regions of the country, as well.
