Massdep GHG Reporting Program Summary Report and Facility List

MassDEP GHG Reporting Program Summary Report and Facility List

Emissions Year 2010

(Revision Date: December 2014)

This document includes 2010 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 second annual summary report published, and the first that includes all six GHGs (only carbon dioxide emissions from fuel combustion were reported for emissions year 2009).

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 2100 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 2010, 302 facilities reported 26,653,516 metric tons of carbon dioxide‐equivalent greenhouse gas emissions to the MA GHG Registry. This represents approximately 32% of the total greenhouse gas emissions inventory for Massachusetts, as most recently estimated for emissions that occurred in 2011.1 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

1 See Massachusetts Annual Greenhouse Gas Emissions Inventory: 1990 through partial 2011 data (July 2014), available at http://www.mass.gov/eea/agencies/massdep/climate-energy/climate/ghg/greenhouse-gas-ghg-emissions-in-massachusetts.html#2. 1 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 81% of the total quantity of carbon‐dioxide equivalent emissions reported to the registry, and the top 10 accounted for 64%. This category includes electric power plants of various types and three large natural gas distribution systems. For most of these facilities, combustion of fossil fuels contributed the vast majority of the emissions. The exceptions were: (1) Five municipal waste combustors and one wood‐fired power plant emitted more than 100,000 tons of carbon dioxide emissions from combustion of biogenic fuels, (2) Three natural gas systems reported more than 100,000 tons of carbon dioxide‐equivalent methane emissions from natural gas leaks, and (3) One facility reported stationary combustion emissions and more than 50,000 tons of emissions from conversion of calcium carbonate to lime. The largest emitter was a coal‐fired power plant.

Motor Vehicle Emissions: 229 facilities reported a total of 125,775 tons of carbon dioxide‐equivalent emissions from motor vehicles, or 0.5% 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): 294 facilities reported a total of 22,576,534 tons of carbon dioxide emissions from fossil fuel combustion, or 85% of the total reported to the registry. Ten large electric power plants accounted for 72% 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).

Biogenic Carbon Dioxide (CO2): 50 facilities reported a total of 2,442,729 metric tons of carbon dioxide emissions from combustion of biogenic material, or 9% of the total reported to the registry. Ten facilities, including seven municipal waste combustors, one wood‐fired power plant and one manufacturing company, accounted for 85% 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): 291 facilities reported a total of 1,151,706 carbon dioxide‐equivalent tons of methane, or 4% of the total reported to the registry. Ten facilities, including natural gas systems, landfills, and one municipal waste combustor, accounted for 77% of the methane emissions.

Nitrous Oxide (N2O): 290 facilities reported a total of 283,720 carbon dioxide‐equivalent tons of nitrous oxide, or 1% of the total reported to the registry. Ten facilities, including electric power plants, one electronic manufacturer, and one water treatment facility, accounted for 73% of the nitrous oxide emissions.

Sulfur Hexafluoride (SF6): 17 facilities reported a total of 78,386 carbon dioxide‐equivalent tons of sulfur hexafluoride, or less than 1% of the total reported to the registry. Ten facilities, including electronics manufacturers, two electric power plants, one academic institution, and one electric switching station, accounted for 99% of the sulfur hexafluoride emissions.

Hydrofluorocarbons and Perfluorocarbons (HFCs and PFCs): 122 facilities reported a total of 119,758 carbon dioxide‐equivalent tons of hydrofluorocarbons and perfluorocarbons, or less than 1% of the total reported to the registry. Ten facilities, including electronics manufacturers and one medical institution, accounted for 77% 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.)
