Scope 2 Emissions
Scope 2 emission sources cover purchased electricity and steam that are vital for the activities of UPitt. These two items usually make up the majority of emissions of any institution. 4.2.1. Purchased Electricity and Steam Purchased electricity and steam are a part of scope 2 emissions of the GHG inventory. Electricity consumption was 198 million kWh for this study period. The CO2 emissions from purchased electricity were calculated using the emission factors present in the CA‐CP calculator. The primary source is from U.S. EPA’s E‐GRID program [15]. E‐GRID has fuel mix information both on a state level, and on a sub‐region level based on fuel mix. UPitt is located in the RFC West power pool (RFCW) (Figure 2) with the majority of electricity generated from coal as presented in (Figure 3). The given regional fuel mix and emissions factors were used to convert electricity consumption into MT CO2E emissions. The results yield 138,700 MT CO2E for electricity consumption.
