For energy transformation and extraction, we use a database of SO2 emissions from global electricity generating units (EGUs) . We use the spatial distribution of SO2 emissions (rather than another pollutant) because SO2 emissions are responsible for the vast majority of overall health impacts from EGUs . EGUs typically have tall emissions stacks, and their emissions plumes often continue to rise after release, owing to their upward velocity exiting the stack and their higher temperature relative to surrounding air. To incorporate stack height and plume rise, we assume that EGUs have stack parameters equal to mean values for EGUs in the year-2014 US EPA National Emissions Inventory (US EPA, 2016) as processed by : 63.5 m stack height, 4.1 m stack diameter, 519.2 K emission temperature and 24.7 m/s emission velocity. (There is no global database of EGU stack properties.)
