CO2 emissions
from fossil-fuel combustion can be estimated at the state or monthly level even
when full data on fuel combustion are not available. Our hypothesis is that a
representative proxy can accurately estimate the pattern of CO2
emissions if a sufficient fraction of the total can be represented, even if the
dataset used does not cover all energy consumption sectors. Our
approach employs monthly sales data for each state from the U.S. Department of
Energy’s Energy Information Administration (EIA). This is used to estimate the
relative proportions of solid, liquid and gaseous fossil fuels for each state
for each month.
