Massdep GHG Reporting Program Summary Report and Facility List

MassDEP GHG Reporting Program Summary Report and Facility List

Emissions Year 2012

(Revision Date: August 2016)

This document includes 2012 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 http://www.mass.gov/dep/air/climate/reporting.htm. 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 fourth annual summary report published, and the third that includes all six GHGs (only carbon dioxide emissions from fuel combustion were reported for emissions year 2009). One of the charts in Part 2 compares emissions over the 2010 – 2012 time period, and shows a clear 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 (CO 2e) 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 2012, 310 facilities reported 20,145,486 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

1 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 77% of the total quantity of carbon-dioxide equivalent emissions reported to the registry, and the top 10 accounted for 58%. This category includes electric power plants of various types, two large natural gas distribution systems, an academic institution and a manufacturer. For most of these facilities, combustion of fossil fuels contributed the vast majority of the emissions. The exceptions were: (1) Five waste-to-energy facilities and one wood-fired power plant each emitted more than 100,000 tons of carbon dioxide emissions from combustion of biogenic fuels, (2) Two natural gas systems each reported more than 100,000 tons of carbon dioxide-equivalent methane emissions from natural gas leaks, (3) One academic institution emitted more than 100,000 tons of carbon dioxide emissions, and (4) One plastics manufacturer emitted more than 100,000 tons of carbon dioxide. The largest emitter was a natural gas-fired power plant. The same facility was also the largest emitter in 2011.

Motor Vehicle Emissions: 247 facilities reported a total of 126,769 tons of carbon dioxide equivalent emissions from motor vehicles, or 0.6% of the total reported to the registry. Only five facilities emitted more than 5,000 tons. (The requirement to report motor vehicle emissions is limited to vehicles that operate in support of a facility, and are owned or leased by that facility.)

Fossil Carbon Dioxide (CO2): 302 facilities reported a total of 16,421,386 tons of carbon dioxide emissions from fossil fuel combustion, or 82% of the total reported to the registry. Ten large electric power plants accounted for 66% of the emissions from combustion of fossil fuels. (A small quantity of other process emissions of non-biogenic carbon dioxide is included in this category2.)

Biogenic Carbon Dioxide (CO2): 55 facilities reported a total of 2,199,233 tons of carbon dioxide emissions from combustion of biogenic material, or 11% of the total reported to the registry. Ten facilities, including seven waste-to-energy facilities, one wood-fired power plant, and two water treatment facilities, accounted for 87% 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

1 See Massachusetts Annual Greenhouse Gas Emissions Inventory: 1990 through 2013, with Partial 2013 Data, available at http://www.mass.gov/eea/agencies/massdep/air/climate/greenhouse-gas-ghg-emissions-in-massachusetts.html. 2 Process emissions are the byproduct of a specific industrial process rather than from the fuel combustion required to conduct that process. For example, a manufacturer that produces cement burns fuel to run the process (these are stationary combustion emissions). The cement itself also releases CO2 during the process because heated limestone breaks down into calcium oxide and CO2 (these are process emissions).

2 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): 306 facilities reported a total of 1,132,445 carbon dioxide-equivalent tons of methane, or 6% of the total reported to the registry. Ten facilities, including natural gas systems, landfills, and a waste-to-energy facility, accounted for 76% of the methane emissions.

Nitrous Oxide (N2O): 304 facilities reported a total of 208,786 carbon dioxide-equivalent tons of nitrous oxide, or 1% of the total reported to the registry. Ten facilities, including electric power plants, a water treatment facility, and waste-to-energy facilities, accounted for 69% of the nitrous oxide emissions.

Sulfur Hexafluoride (SF6): 17 facilities reported a total of 67,948 carbon dioxide-equivalent tons of sulfur hexafluoride, or 0.3% of the total reported to the registry. Ten facilities, including electronics manufacturers, an academic institution, an electric switching station, an electricity transmission facility, and a research and development facility, accounted for 96% of the sulfur hexafluoride emissions.

Hydrofluorocarbons and Perfluorocarbons (HFCs and PFCs): 156 facilities reported a total of 107,932 carbon dioxide-equivalent tons of hydrofluorocarbons and perfluorocarbons, or 0.5% of the total reported to the registry. Ten facilities, including manufacturers and, research institutions, accounted for 78% 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 The Climate Registry’s General Reporting Protocol.)

3 4 5 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.
