Footnotes:

a Beginning in 1978, consumption data not collected and assumed to be zero.

b Transportation use of natural gas to operate pipelines and as vehicle fuel. Excludes supplemental gaseous fuels.

c Excludes biofuels.

d Hydrocarbon gas liquids, assumed to be propane only.

— = No consumption. Where shown, R = Revised data and (s) = Value less than 0.5.

Notes: · Data are carbon dioxide (CO2) emissions estimates from fossil fuels primary energy consumption, excluding renewable energy. The state data do not account for interstate flow of electricity and represent CO2 emissions in the state where fossil fuels are burned to generate electricity, although the electricity might be sold to ultimate customers in other states and sectors. · Totals may not equal sum of components due to independent rounding. · The continuity of these data series estimates may be affected by changing data sources and estimation methodologies. See the technical notes for each type of energy.
