Massdep GHG Reporting Program Summary Report and Facility List

MassDEP GHG Reporting Program Summary Report and Facility List

Emissions Year 2015

(Publication Date: August 2016)

This document includes 2015 greenhouse gas emissions data reported to the Massachusetts GHG Registry by facilities in Massachusetts. The Massachusetts GHG Registry is an electronic greenhouse gas (GHG) emissions registry that was created by MassDEP and The Climate Registry to address requirements of the Massachusetts Global Warming Solutions Act. Additional information about the MassDEP GHG reporting program is available at www.mass.gov/dep/ghgreporting. The document includes two parts: Part 1 summarizes key information in charts and narrative form, and Part 2 lists all facilities that reported greenhouse gas emissions to the MA GHG Registry. This is the seventh annual summary report published, and the sixth that includes all six GHGs (only carbon dioxide emissions from fuel combustion were reported for emissions year 2009). One of the charts compares emissions over the 2010 – 2015 time period, and shows a general trend toward reduced emissions of carbon dioxide from combustion of fossil fuels. This trend is largely attributable to reduced emissions from coal combustion at power plants in Massachusetts.

All quantities included in this report are expressed in carbon dioxide equivalent metric tons. Carbon dioxide equivalent (CO2e) means that for gases other than carbon dioxide, the number of tons of emissions is adjusted to account for differing global warming potentials. For example, since the MA GHG Registry uses a global warming potential of 21 for methane, if a source were to emit 100 metric tons of methane, this report would show 2,100 tons under the methane (CH4) column heading. For more information about greenhouse gases and global warming potentials, consult The Climate Registry’s General Reporting Protocol, available at http://www.theclimateregistry.org/resources/protocols/general-reporting-protocol/.

Part I: Summary Report

For emissions year 2015, 296 facilities reported 18,959,938 metric tons of carbon dioxide-equivalent greenhouse gas emissions to the MA GHG Registry. This represents approximately one quarter of the total greenhouse gas emissions inventory for Massachusetts, as most recently estimated for emissions that occurred in 2012.[1] When considering the information below, it is very important to understand that only emissions from large stationary facilities are reported to the MA GHG Registry. Emissions from sources such as motor vehicles, residential and commercial space and water heating, and leaking refrigeration systems are not reported unless they are located at a large facility that reports greenhouse gas emissions to the MA GHG Registry.

The Largest Emitters: The twenty-five largest emitters emitted 76% of the total quantity of carbon dioxide-equivalent emissions reported to the registry, and the top 10 accounted for 53%. The twenty-five largest emitters include electric power plants of various types, two large natural gas distribution systems, an academic institution, a sewage treatment facility, and a manufacturer. For most of these facilities, combustion of fossil fuels contributed to the vast majority of their emissions. The exceptions were: (1) five waste-to-energy facilities, 55%-58% of whose emissions came from carbon dioxide emitted through combustion of biogenic fuels (biogenic CO2), (2) one wood-fired power plant, 98% of whose emissions were biogenic CO2, (3) one sewage treatment facility, 40% of whose emissions were biogenic CO2 and 25% were nitrous oxide (N2O); (4) two natural gas distributors, 96% and 83% of whose emissions were methane, respectively, largely due to natural gas leaks. The largest emitter was a coal-fired power plant.

Motor Vehicle Emissions: 243 facilities reported a total of 146,403 tons of carbon dioxide equivalent emissions from motor vehicles, or only 0.77% of the total reported to the registry. Only six facilities emitted more than 5,000 tons. The top ten emitters accounted for 53% of the motor vehicle emissions. For most facilities, motor vehicle emission accounted for a very small percentage of their total emissions. (The requirement to report motor vehicle emissions is limited to vehicles that operate in support of a facility that triggered the reporting requirement based on emissions from stationary sources, and are owned or leased by that facility.)

Fossil Carbon Dioxide (CO2): 293 facilities reported a total of 15,256,442 tons of carbon dioxide emissions from fossil fuel combustion, or 80% of the total reported to the registry. The top ten emitters, consisting of ten fossil fuel electric power generation facilities, accounted for 61% of the emissions from combustion of fossil fuels. (A small quantity of other process emissions of non-biogenic carbon dioxide is included in this category.[2])

Biogenic Carbon Dioxide (CO2): 51 facilities reported a total of 2,263,380 tons of carbon dioxide emissions from combustion of biogenic material, or 12% of the total reported to the registry. Ten facilities, including six waste-to-energy facilities, one wood-fired power plant, one sewage treatment facility, one paper mill, and one manufacturer, accounted for 88% of the emissions from combustion of biogenic material. (Biogenic carbon dioxide emissions include emissions from combustion of biomass, biofuels, municipal solid waste, and landfill gas, and any carbon dioxide emitted as a component of landfill gas. Separate reporting of biogenic emissions from blended biofuels in motor vehicles was not required because of technical limitations in the software platform; instead reporters were allowed to quantify these emissions using emission factors intended for the corresponding petroleum-based fuel. For example, a facility that combusted 100 gallons of gasoline-ethanol blended fuel was allowed to report the combustion of 100 gallons of petroleum-based gasoline.)

Methane (CH4): 292 facilities reported a total of 1,090,279 carbon dioxide-equivalent tons of methane, or 5.8% of the total reported to the registry. Ten facilities, including six natural gas distribution systems, three solid waste landfills, and one waste-to-energy facility, accounted for 75% of the methane emissions.

Nitrous Oxide (N2O): 290 facilities reported a total of 179,147 carbon dioxide-equivalent tons of nitrous oxide, or 0.9% of the total reported to the registry. Ten facilities, including five electric power plants, four solid waste incinerators, and one sewage treatment plant, accounted for 71% of the nitrous oxide emissions.

Sulfur Hexafluoride (SF6): 24 facilities reported a total of 48,452 carbon dioxide-equivalent tons of sulfur hexafluoride, or 0.3% of the total reported to the registry. Ten facilities, including five semiconductor manufacturers, two electric power transmission and control stations, one plastics manufacturer, one electric power plant, and one academic institution, accounted for 93% of the sulfur hexafluoride emissions.

Hydrofluorocarbons and Perfluorocarbons (HFCs and PFCs): 156 facilities reported a total of 106,774 carbon dioxide-equivalent tons of hydrofluorocarbons and perfluorocarbons, or 0.6% of the total reported to the registry. Ten facilities, including various facilities such as manufacturers and research institutions, accounted for 70% of these emissions. (Hydrofluorocarbons and perfluorocarbons are used as refrigerants, and by electronics manufacturers. Each gas in this category has a different global warming potential. More information is available in The Climate Registry’s General Reporting Protocol.)

The sectors within this chart are categorized by Institutions, Manufacturing, Natural Gas and Petroleum Infrastructure, Power Generation, Waste Management, and Other. Institutions include hospitals, universities, hotels, correctional facilities, and national security institutions. Manufacturing includes material manufacturing, pharmecuetical preparation, and paper and fabric finishing mills. Natural Gas and Petroleum Infrastructure includes transmission and distribution of natural gas, and oil terminals. Power Generation facilities include fossil, biomass, and landfill gas-powered EGUs. Waste Management facilities include landfills, sewage treatment, and waste-to-energy facilities. Other includes transportation systems and steam and air conditioning suppliers.
