How Connecticut’s carbon emissions compare with other states’

Print More

Connecticut is among states that saw a drop in carbon emissions from fossil fuel consumption, with a decline of 6.5 million metric tons, or 15.9%, from 1990 to 2013.

That’s according to data from U.S. Energy Information Administration. The EIA reported that 37 states saw a drop in CO2 emissions from 2000 to 2013, while 13 saw an increase. The 5.4 billion metric tons of CO2 emitted in 2000 was near the peak for nationwide emissions.

Fewer states have seen declines going as far back as 1990. TrendCT found 19 states and the District of Columbia saw declines over that period, while 32 states saw increases.

To adjust for the year-to-year swings, Trend compared averages for CO2 emissions from the first five years and last five years of the period for which data was available, 1990 to 2013:

Connecticut saw declines by both measures.

Trend looked at total carbon emissions by state and found Connecticut had among the smallest footprints.

But some highly populated states have high carbon footprints, so we looked at per-capita carbon emissions as well.

Where does the CO2 come from?

The largest share of Connecticut’s carbon emissions from fossil fuel consumption come from transportation. Other sectors include electricity generation, industry and the commercial and residential sectors.
