Carbon Dioxide Equivalent. The amount of carbon dioxide by weight that would produce the same amount of global warming impact as a given weight of another greenhouse gas, based on the best available science, including information from the Intergovernmental Panel on Climate Change. The global warming potentials included in 40 CFR Part 98 shall be used to quantify and report greenhouse gas emissions in carbon dioxide equivalents pursuant to 310 CMR 7.71.
Entity. A person that owns or operates, in whole or in part, a source of greenhouse gas emissions from a generator of electricity or a commercial or industrial site including, but not limited to, a transportation fleet.
Facility. A building, structure or installation located on contiguous or adjacent properties of an entity, or a natural gas facility.
Greenhouse Gas. Any chemical or physical substance that is emitted into the air and that the Department may reasonably anticipate will cause or contribute to climate change including, but not limited to, carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and any other gas for which 40 CFR Part 98 includes a method for calculating greenhouse gas emissions from any stationary emissions source.
Method. A way of calculating greenhouse gas emissions provided in 40 CFR Part 98 and any related monitoring, reporting, and recordkeeping requirements included in 40 CFR Part 98, but does not mean a reporting threshold, specific source category exemption, or any other type of requirement.
Natural Gas Facility. A collection of interconnected natural gas containing equipment (e.g., transmission and distribution pipelines, service lines, customer meters, compressors, tanks, metering stations, regulating stations, and any other interconnected equipment that contains natural gas) that is owned or operated by an entity.
Short Ton. 2000 pounds or 0.9072 metric tons.
Stationary Emission Source. Any individual stationary piece of equipment or other stationary point from which any greenhouse gas is emitted to the ambient air. For the purpose of reporting greenhouse gas emissions pursuant to 310 CMR 7.71, a source of greenhouse gas emissions located within the facility is a stationary emission source if 40 CFR Part 98 includes a method for calculating greenhouse gas emissions that can be used to quantify emissions from the source.
