  1. Emissions of FFCO2 for Hestia-Baltimore and CO2e for the SRI are reported in kilotonnes of carbon (kt C). The 95% confidence intervals for Hestia-Baltimore emissions are provided in parentheses. The SRI includes emissions of methane and nitrous oxide as well. “NA” denotes a Scope 2 emissions category that was never intended to be quantified in Hestia-Baltimore Scope 1 emissions
  2. aHestia-Baltimore includes negligible emissions from coal consumption in the residential and commercial sectors
  3. bOnroad emissions in Hestia were disaggregated by fuel type (gasoline and diesel) while the onroad emissions in the SRI were disaggregated by vehicle class. The sum of onroad emissions from all fuels and vehicle classes is presented in the table
  4. cThe SRI includes emissions from electricity generation from facilities that are not within the geographical city boundary in the Scope 1 total, though these are not technically Scope 1 emissions for the City. The reported Scope 1 FFCO2 emissions for only the facilities that are within the city boundary total 103.0 kt C
  5. dHestia-Baltimore only contains rail emissions from fossil fuel burned by prime movers on trains and emissions from railyards while the SRI only contains Scope 2 emissions from electrified railways
  6. eThe totals in reported in the SRI do not include emissions from energy generation supplied to the grid because these emissions would be double counted with Scope 2 emission. In this manuscript, Scope 1 emissions from the SRI are quantified and included in the comparison with Hestia-Baltimore (Tables 5 and 6)
