NJ's Emissions Profile

Statewide Greenhouse Gas (GHG) Emissions Inventory

The latest 2018 Greenhouse Gas Emissions Inventory covers statewide emissions for the years 2016, 2017, and 2018. Estimated net greenhouse gas emissions are as follows: 103.3 million metric tons of carbon dioxide equivalent (MMTCO2e) in 2016; 97.0 MMTCO2e in 2017; 97.0 MMTCO2e in 2018. The sectoral distribution of the GHG emissions for 2018 is shown below:

New Jersey Statewide Greenhouse Gas Emissions Inventory Update: 2018 Estimates (2019)

As with previous inventory years, The four leading sources of GHG emissions in 2018 are transportation, electricity generation, commercial and industrial fossil fuel use, and residential fossil fuel use.

Transportation remains the largest source at 40.6 MMTCO2e, which is 42% of the net statewide GHG emissions. Electricity generation follows as the next largest source at 18.1 MMTCO2e, which is 19% of Statewide GHG emissions.

The contribution of commercial and industrial fuel use is 16.6 MMTCO2e, which is 17% of the net emissions, while residential fossil fuel use reached 15.2 MMTCO2e, or 16% of the net total.

On the other hand, carbon captured by the State’s natural sinks (growth of forests and other vegetation plus soils left undisturbed) held steady at 8.1 MMTCO2e in 2018, “offsetting” 8% of the gross Statewide GHG emissions.

What are the Trends Towards GWRA Goals?

The Global Warming Response Act (N.J.S.A 26:2C-37) calls for a reduction of Statewide greenhouse gas emissions to 80 percent below 2006 levels by 2050, which equates to 24.1 million metric tons of carbon dioxide equivalent (MMT CO2e). According to the latest GHG emissions estimate (2018), Statewide releases 97 MMT CO2e, with 86% of those emissions coming from the combustion of fossil fuels to satisfy energy demand and transportation.  

Achievement of the 2050 emissions reduction goal will require a degree of emissions reduction that is far more pronounced than will be necessary to achieve the 2020 limit, although New Jersey’s attainment of the 2020 reduction goal years ahead of schedule attests to the success of efforts thus far.

New Jersey’s Criteria Pollutants Profile: Comparison with Other States

New Jersey has some of the lowest emission rates from power plants in the country. According to the U.S. Energy Information Administration (EIA) data, New Jersey’s sulfur dioxide (SO2) emission rate is amongst the five lowest, nitrogen oxide (NOx) emission rate among the three lowest, and carbon dioxide (CO2) emission rate are amongst the nine lowest among States in the nation. In comparison to the 13-State PJM regional transmission region, New Jersey ranks, by far, the lowest of all.
