Glossary of Terms



Additionality:  Term used to describe the fact that a carbon reduction or renewable energy project would not have occurred had it not taken into account its ability to sell carbon offsets or renewable energy credits (RECs), respectively. More succinctly, a project has proven additionality if it is beyond business-as-usual.

Afforestation:  Establishing a forest on land that is not a forest, or has not been a forest for a long time by planting trees or their seeds.

Alternative Energy:  Renewable sources of power not derived from burning hydrocarbons, which emit less (or no) greenhouse gas.  "Old renewables" include nuclear and less (or no) greenhouse gas.  "Old renewables" include nuclear and hydroelectric power, "new renewables" include solar and wind power.

AMMP Rating:  The AMMP Rating is "Average Miles Per Pound" which is a measure like MPG or miles per gallon, but perhaps a more effective measurement in today’s mixed fleet environment. It is calculated by dividing the miles a vehicle travels in a period by the pounds of carbon emitted in the process of driving those miles. The "pounds of carbon dioxide emitted" are calculated by multiplying the units of fuel consumed times the emission rate for the particular type of fuel consumed. For gasoline, the rate is 19.2 pounds of Carbon Dioxide emitted for each gallon of gasoline consumed.

Annual Electricity Consumption:  Refers to the amount of electricity used by a consumer in one year and is typically measured in kilowatt-hours (kWh). This information can be acquired from your electricity bill or by contacting your energy provider.

APPSF Base Rating:  The APPSF Base Rating is “Average Per Pound Square Foot” is calculated by the dividing the total pounds of carbon emitted by a property, (prior to purchasing any carbon offsets) by the total square footage of the property or portfolio of properties.


Baseline:  Accurately comparing and reducing energy consumption and greenhouse gas emissions requires preliminary data gathering to establish baseline measures as a cornerstone for setting climate neutrality goals and targets during the strategic planning process and for measuring progress toward those goals. The baseline inventory also provides a common data set for establishing benchmarks and priorities during the strategic planning stage and a means for estimating associated resource costs and benefits.

Behavior Change:  Behavior change can refer to any transformation or modification of human behavior. Behavior change includes a broad range of activities and approaches which focus on the individual, community, and environmental influences on behavior.

Business Intelligence:  Refers to skills, processes, technologies, applications and practices used to support decision making.

Business unit:  A unit that is recognized by an entity as having administrative responsibility for one or more facilities or departments of and organization.

Cap and Trade:  Approach used to control carbon dioxide pollution by providing economic incentives for achieving reductions in emissions. A cap for pollution is established and reduced overtime. Companies that reduce their emissions faster than the cap can trade their extra reductions to companies that have reduced their emissions more slowly.

Carbon Dioxide (CO2):  CO2 is a colorless, odorless chemical compound built of two oxygen atoms covalently bonded to a single carbon atom. Carbon dioxide pollution is the leading cause of climate change.

Carbon dioxide equivalence (CO2-e):  A standard measure that takes account of the different global warming potentials of greenhouse gases and expresses the cumulative effect in a common unit.

Carbon Footprint:  A measure of your environmental impact from everyday activities such as flying, driving, and using electricity.  A “carbon footprint” is most often expressed in pounds or metric tons of carbon dioxide.

Carbon Monoxide:  Colorless, odorless gas resulting from the incomplete combustion of hydrocarbon fuels. Carbon monoxide interferes with blood's ability to carry oxygen to the body's tissues and results in numerous adverse health effects.

Carbon Neutral:  The means for individuals and corporations to neutralize their GHG emissions by reduction strategies and offsets through carbon credits.

Carbon Offsets:  Allow consumers to reduce the environmental impact of their lifestyles beyond what they are able to conserve. By purchasing carbon offsets in the form of verified emission reductions (VERs) equal to the estimated impact of ones driving or flying, an individual can reduce their impact and do their part to fight climate change.

Carbon Reduction Project:  A business initiative that receives funding because of the reduction in emissions of greenhouse gases (GHGs) that will result from the projects efforts.

Carbon Sink:  A natural or manmade reservoir that accumulates and stores carbon dioxide for an indefinite period.

Certified Emission Reduction (CER):  A Kyoto unit corresponding to one metric tonne of carbon dioxide equivalent emissions, and issued for verified emission reductions or removals achieved by projects approved under the Clean Development Mechanism (CDM). CDM projects undertaking afforestation and reforestation activities issue temporary and long term units known as tCERs and lCERs, which must be replaced after a specified period.

Clean Development Mechanism (CDM):  The CDM allows greenhouse gas emission reduction projects to take place in countries that have no emission targets under the Kyoto Protocol, yet are signatories.  The CDM is defined in Article 12 of the Kyoto Protocol.

Climate Change:  Refers to any significant change in measures of climate (such as temperature, precipitation, or wind) lasting for an extended period (decades or longer). Climate change may result from: a.) Natural factors, such as changes in the sun's intensity or slow changes in the earth's orbit around the sun. b.) Natural processes within the climate system (e.g. changes in ocean circulation) c.) Human activities that change the atmosphere's composition (e.g., through burning fossil fuels) and the land surface (e.g., deforestation, reforestation, urbanization, desertification, etc.).

Coal:  Formed from plant and animal matter that has been subjected to geologic heat and pressure, transformed over millions of years into hard black solids. Because coal is a readily available resource in the United States, coal power plants provide about half of the nation's electricity. However, coal-fired power plants generally cause more pollution per unit of electricity than any other fuel. Most coal plants are required to have several pollution control devices to reduce the amount of pollutants that are released into the air from burning the coal. These controls have played an important role in cleaning up air quality in many areas of the country.

Combined heat and power (CHP):  Also known as cogeneration, is an efficient, clean, and reliable approach to generating power and thermal energy from a single fuel source. CHP is not a specific technology but an application of technologies to meet an energy user's needs. CHP systems achieve typical effective electric efficiencies of 50 to 80 percent — a dramatic improvement over the average efficiency of separate heat and power. Since CHP is highly efficient, it reduces traditional air pollutants and carbon dioxide, the leading greenhouse gas associated with climate change.  Visit EPA’s Combined Heat and Power Partnership web site for additional information.

Commercial Energy Customer:  A commercial energy customer refers to non-industrial customers occupying retail space or office buildings.

Commodity:  Reasonably homogeneous good or material, bought and sold freely as an article of commerce. In terms of energy and resources consumption, commodity refers to both primary and secondary energy, such as electricity, natural gas, propane, gasoline, diesel fuel, water, waste, etc.   

Conventional Electricity:  Electricity generated from non-renewable sources like fossil fuels. Conventional fuel sources include coal, natural gas, oil, nuclear, and large hydro.

Cost Avoidance:  Action taken to reduce future costs. Cost avoidance is the calculated value of the difference between what we actually spend on utilities and what we would have spent had we maintained our old habits and methods of using energy.

Dioxins:  Man-made chemical compounds that enter the air through fuel and waste emissions, including motor vehicle exhaust fumes and garbage incineration. Skin rashes, liver damage, weight loss, and a reduction in the effectiveness of the immune system have all been attributed to human exposure to dioxins.

Emissions:  The release of substances, such as greenhouse gases, into the atmosphere. Emissions caps are legal limits on how much greenhouse gas a business, city or nation can emit.

Emission factor:  A factor that gives the kilograms of carbon dioxide equivalent emitted per unit of activity.

Emissions Reduction Unit (ERU)
:  A Kyoto unit corresponding to one metric tonne of carbon dioxide equivalent emissions reduced or sequestered arising from a Joint Implementation (defined in Article 6 of the Kyoto Protocol) project.

Energy Consumption:  The consumption of energy or power.

Energy Efficiency:  Energy efficiency refers to products or systems using less energy to do the same or better job than conventional products or systems. Energy efficiency saves energy, saves money on utility bills, and helps protect the environment by reducing the amount of electricity that needs to be generated.

Energy Management:  Energy management is the process of monitoring, controlling, and conserving energy in a building or organization, business and homes. Typically this involves the following steps:  1. Metering your energy consumption and collecting the data.  2. Finding opportunities to save energy, and estimating how much energy each opportunity could save. You would typically analyze your meter data to find and quantify routine energy waste, and you might also investigate the energy savings that you could make by replacing equipment (e.g. lighting) or by upgrading your building's insulation.  3. Taking action to target the opportunities to save energy (i.e. tackling the routine waste and replacing or upgrading the inefficient equipment). Typically you would start with the best opportunities first.  4. Tracking your progress by analyzing your meter data to see how well your energy-saving efforts have worked.

Environmental Resources Trust (ERT):  A Washington, DC-based, non-profit organization founded in 1996 to pioneer the use of market forces to protect and improve the global environment. ERT verifies carbon offsets, among their other environmental projects.

Environmental Protection Agency (EPA): A government agency that leads United States environmental science, research, education and assessment efforts. The mission of the Environmental Protection Agency is to protect human health and the environment. Since 1970, EPA has been working for a cleaner, healthier environment for the American people.

Fossil Fuels:  Fossil Fuels are hydrocarbons that come in three major forms- coal, oil, and natural gas). Most electricity today is generated by burning fossil fuels. The burning of fossil fuels causes emissions of carbon dioxide, the leading cause of climate change.  Because fossil fuels are a finite resource and cannot be replenished once they are extracted and burned, they are not considered renewable.

Functional Unit:  A means of expressing the greenhouse gas emissions of a product in a way that is meaningful for the product being investigated (for example kilograms of CO2-e per unit of product).

Green Power:  Electricity that is generated from renewable energy sources is often referred to as “green power.” Green power products can include electricity generated exclusively from renewable resources or, more frequently, electricity produced from a combination of fossil and renewable resources. Also known as “blended” products, these products typically have lower prices than 100 percent renewable products. Customers who take advantage of these options usually pay a premium for having some or all of their electricity produced from renewable resources. To find out more about green power, visit EPA’s Green Power Partnership Web site.

Green Pricing:  Refers to an optional utility service that allows customers of traditional utilities support a greater level of utility investment in renewable energy by paying a premium on their electric bill to cover any above-market costs of acquiring renewable energy resources.

Greenhouse Gas (GHG):  Greenhouse gases are gaseous constituents of the atmosphere, both natural and manmade that effect the temperature of the earth. The primary gases (both naturally existing and manmade) that contribute to global warming by trapping more energy in the earth’s atmosphere than would occur in their absence.  The six Kyoto Protocol classes of greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6).

Gold Standard:  An offset standard based on the Kyoto Protocols clean development mechanism and developed by several international non-profit organizations. This standard certification is for renewable energy efficiency projects.

Ground-level Ozone:  Is formed by a chemical reaction between volatile organic compounds and oxides of nitrogen in the presence of sunlight. Ozone concentrations can reach unhealthful levels when the weather is hot and sunny with little or no wind. High concentrations of ozone near ground level are harmful to people, animals, crops, and other materials.
Haze:  Consists of sufficient smoke, dust, moisture, and vapor suspended in air to impair visibility. The term regional haze means haze that impairs visibility in all directions over a large area.


Hydroelectric Power:  The process of generating electricity by harnessing the power of moving water is called hydroelectricity. Hydroelectric power (hydropower) is generated by forcing water that is flowing downstream, often from behind a dam, through a hydraulic turbine that is connected to a generator. The water exits the turbine and is returned to the stream or riverbed. Much of the hydroelectricity in the United States is generated at large facilities and in the Pacific Northwest, where it meets about two-thirds of the electricity demand. In the U. S., hydroelectricity contributes about 10 percent of the total electricity supply.

Industrial Air Pollution:  This term refers to the emissions of the following pollutants: sulfur oxides, nitrogen oxides, mercury, and carbon dioxide. These air emissions contribute to such environmental concerns as urban smog; acid deposition; excessive nutrient loads to important bodies of water, such as the Chesapeake Bay; haze in national parks and wilderness areas; and global climate change.

Industrial Energy Customer:  Include businesses involved in manufacturing or industrial processing.

Kilowatt Hour:  Is a unit of energy equal to 1,000 watt-hours. Power companies produce energy which is often purchased by the customer in units of kilowatt hours. Many electric utility companies use the kilowatt hour for billing because the typical consumer can readily conceptualize the notion of “using a kilowatt for one hour.” Megawatt-hours are used for metering of larger amounts of electrical energy. For example, a power plant’s daily output is likely to be measured in megawatt-hours.

Kyoto Protocol:  An internationally binding agreement that falls under the more general United Nations Framework Convention and Climate Change (UNFCCC). The Protocol sets GHG targets for countries that sign and ratify the agreement. Even though the United States has not ratified the agreement, the United States is responsible for 25% of the world's hydrocarbon emissions and has a voluntary program. States and municipalities are putting legislation in effect to meet the Kyoto Protocol guideline.

Kyoto Unit:  An emissions unit recognized for compliance under the Kyoto Protocol. Kyoto units include Assigned Amount Units (AAUs), CERs (including tCERs and lCERs), ERUs and Removal Units (RMUs).

LEED Certification (Leadership in Energy and Environmental Design):  The main route to certifying a green building. This includes new building construction and major renovation projects. LEED certified buildings enjoy government incentives, marketing benefits, increased property values and lower utility/energy costs.

Life Cycle Assessment: The compilation and evaluation of the inputs, outputs and the potential environmental impacts of a product system throughout its life cycle.

Line Losses:  The amount of energy lost during transmission and distribution of electricity, including unaccounted for uses.

Megawatt Hour:  One thousand kilowatt hours.  1 Megawatt = 1000 KW or 1,000,000 watts. One megawatt is enough electrical energy to power 1000 average homes.

Mercury/Mercury Compounds:  Mercury is a toxic heavy metal that is a byproduct of thermo combustion of fossil fuels, especially coal. Mercury and compounds containing mercury can accumulate in the environment and are highly toxic to humans and animals if inhaled or swallowed. Exposure can permanently damage the brain, kidneys, and fetuses.

Methane (CH4):  A hydrocarbon that is a greenhouse gas with a global warming potential most recently estimated at 23 times that of carbon dioxide (CO2). Methane is produced through anaerobic (without oxygen) decomposition of waste in landfills, animal digestion, decomposition of animal wastes, production and distribution of natural gas and petroleum, coal production, and incomplete fossil fuel combustion. The global warming potential (GWP) is from the Intergovernmental Panel on Climate Change’s (IPCC's) Third Assessment Report (TAR).

Metric Ton:  A metric ton is the unit of measurement used for large amounts of carbon dioxide. This “ton” based on the metric system, rather than the standard system used in the United States. A metric ton is equivalent to 1,000 kilograms, or 2,204.62262 pounds.

Natural Gas:  Underground deposits of gases consisting of 50 to 90 percent methane (Ch3) and small amounts of heavier gaseous hydrocarbon compounds such as propane (C3H8) and butane (C4H10).

Nitrogen Oxides (NOX):  Gases consisting of one molecule of nitrogen and varying numbers of oxygen molecules. Nitrogen oxides are produced in the emissions of vehicle exhausts and from power stations. In the atmosphere, nitrogen oxides can contribute to formation of photochemical ozone (smog), can impair visibility, and have health consequences; they are thus considered pollutants.

Nuclear Energy:  Nuclear energy originates from the splitting of uranium atoms in a process called fission. At the power plant, the fission process is used to generate heat for producing steam, which is used by a turbine to generate electricity. Because nuclear power plants do not burn fuel, they do not emit air pollutant emissions. All of the nuclear power plants in the United States collectively produce about 2,000 metric tons per year of radioactive waste. Abandoned uranium mines contaminated with high-level radioactive waste can continue to pose radioactive risks for as long as 250,000 years after closure. There are more than 60 nuclear power plants currently in operation in the U.S., which accounts for approximately 20 percent of the country’s electricity production. No nuclear power plants have been built since 1996, mostly due to economic factors and environmental concerns.

Oil:  A liquid fossil fuel, is formed from layers of buried plants and animals that have been subjected to geologic heat and pressure over a long period of time. The energy that the plants and animals originally obtained from the sun is stored in the oil in the form of carbon. In addition to carbon, oil contains elements such as nitrogen, sulfur, mercury, lead, and arsenic. Oil is a nonrenewable resource because it cannot be replenished on a human time frame.

Particulate Matter (PM):  Very small pieces of solid or liquid matter, such as particles of soot, dust, fumes, mists, or aerosols. The physical characteristics of particles, and how they combine with other particles, are part of the feedback mechanisms of the atmosphere.

Permanence:  With regard to carbon offsets, permanence requires the generation of offsets to have actually occurred and the carbon stored or sequestered not to be released into the atmosphere in the future.

Pounds of Carbon Dioxide Emitted:  The pounds of carbon dioxide emitted are calculated by multiplying the unit quantity of energy consumed (by type) by the applicable conversion rate for your geographic area at a point in time.


Power Grid:  Electric power transmission (sometimes referred to as a grid) is a process in the transmitting of electricity to consumers. The term refers to the bulk transfer of electrical power from place to place. Typically, power transmission is between the power plant and a substation near a populated area. It is then distributed from the substation to consumers.



Primary Energy: As opposed to secondary energy, it is energy embodied in sources which involve human induced extraction or capture, that may include separation from contiguous material, cleaning or grading, to make the energy available for trade, use or transformation. For example, coal is considered a primary energy that can be converted to electricity, a secondary energy. 


RAMPP Rating:  The RAMMP Rating is the "Recorded Average Miles Per Pound" for a fleet is calculated by dividing the miles a fleet travels in a period by the total pounds of carbon emitted by the fleet in the process of driving those miles.



Reforestation:  Restoring and recreating areas of woodlands or forest that once existed but were deforested or otherwise removed or destroyed in the past.



Regional Greenhouse Gas Initiative (RGGI):  Is a regional initiative by states in the Northeastern United States to reduce greenhouse gas emissions with a cap and trade system.



Removal Unit (RMU):  A Kyoto unit corresponding to one metric tonne of carbon dioxide equivalent emissions sequestered and issued for removals of carbon dioxide from the atmosphere by eligible land use, land use change and forestry activities.


Renewable Energy:  The term renewable energy generally refers to electricity supplied from renewable energy sources, such as wind and solar power, geothermal, hydropower, and various forms of biomass. These energy sources are considered renewable sources because they are continuously replenished on the Earth.



Renewable Energy Certificate:  A certificate that represents the environmental attributes of 1 MWh of electricity from a renewable energy source.



Renewable Energy Credits (RECs):  Are also know as Green tags or Tradable Renewable Certificates (TRCs). They are a market mechanism that represents the environmental benefits associated with generating electricity from renewable energy sources. A wind farm is credited with one Renewable Energy Credit for every 1000 kWh of electricity it produces. A certifying agency gives each REC a unique identification number to make sure it doesn't get double-counted. The clean energy is then fed into the electrical grid.



Renewable Portfolio Standard (RPS):  Regulatory policy that requires the increased production of renewable energy sources such as wind, solar, biomass, and geothermal energies.



Retail Competition:  In states with retail competition, consumers have the opportunity to choose their energy provider and purchase products based on the price or on the source of power supplied to their home or business.


Scope 1 emissions:  The release of greenhouse gas into the atmosphere as a direct result of activities at a Facility; for example, natural gas or propane combustion.



Scope 2 emissions:  The release of greenhouse gas as an indirect result of energy consumption by a Facility; for example, electricity usage.



Scope 3 emissions:  The release of greenhouse gas into the atmosphere that is generated in the wider economy as a consequence of a facility’s activities but that are physically produced by another Facility.



Secondary Energy: As opposed to primary energy, this energy is embodied in commodities that come from human induced energy transformation. For example, coal is considered a primary energy that can be converted to electricity, a secondary energy.



Sequestration:  The removal of atmospheric carbon dioxide, either through biological processes (for example, photosynthesis in plants and trees), or geological processes (for example, storage of carbon dioxide in underground reservoirs).



Sinks:  A natural reservoir that withdraws and traps a pollutant. Soil and plants act as carbon sinks, for instance.



Small Hydro:  In addition to very large hydro plants in the West, the United States has many smaller hydro plants. Like large plants, small-scale hydroelectric systems capture the energy in flowing water and convert it to electricity. Although the potential for small hydroelectric systems depends on the availability of suitable water flow, these systems can provide cheap, clean, reliable electricity where the resource exists.



Smog:  Brownish haze that pollutes our air, particularly over cities in the summertime. Smog can make it difficult for some people to breathe and it greatly reduces how far we can see through the air. The primary component of smog is ozone, a gas that is created when nitrogen oxides react with other chemicals in the atmosphere, especially in strong sunlight.



Sulfur Dioxide:  High concentrations of sulfur dioxide affect breathing and may aggravate existing respiratory and cardiovascular disease. Sensitive populations include asthmatics, individuals with bronchitis or emphysema, children, and the elderly. Sulfur dioxide is also a primary contributor to acid rain, which causes acidification of lakes and streams and can damage trees, crops, historic buildings, and statues. In addition, sulfur compounds in the air contribute to visibility impairment in large parts of the country. This is especially noticeable in national parks. Sulfur dioxide is released primarily from burning fuels that contain sulfur (such as coal, oil, and diesel fuel). Stationary sources such as coal- and oil-fired power plants, steel mills, refineries, pulp and paper mills, and nonferrous smelters are the largest releasers.



Sustainability: a.) method of using a resource so that the resource is not depleted or permanently damaged.  b.) of or relating to a lifestyle involving the use of sustainable methods. See the white paper GreenTraking for Profit and Planet for more on Sustainability.



The Standard:  National Carbon Offset Standard.



United Nations Framework Convention on Climate Change (UNFCCC):  An international treaty, adopted in 1992, aimed at achieving the stabilisation of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.



Utility:  A utility is a municipal or private business that provides electricity to the public and is subject to governmental regulation.


Verified Carbon Unit (VCU): A unit corresponding to one metric tonne of carbon dioxide equivalent emissions reduced, certified and issued under the Verified Carbon Standard.



Voluntary Carbon Standard (VCS): Program that sets forth strenuous quality standards for and verification of carbon offsets.



Voluntary Emissions Reduction (VER): Emission reduction units that have been generated according to defined voluntary standards.


White Tag:  A certificate equivalent to 1 MWh of energy savings.



Wind Farm: Collection of wind turbines in the same location and is used for the generation of wind power electricity. A wind turbine is a machine for converting the kinetic energy in wind into mechanical energy. If the mechanical energy is used directly by machinery, such as a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator.



Wind Power: Conversion of wind energy into electricity using wind turbines. Globally, wind power generation more than quadrupled between 1999 and 2005. Most modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical currents by means of an electrical generator. Wind power is used in large scale wind farms for national electrical grids as well as in small individual turbines for providing electricity to rural residences or grid-isolated locations. Wind energy is ample, renewable, widely distributed, clean, and reduces the greenhouse effect when used to replace fossil-fuel-derived electricity.



Wind Turbine:  A rotary engine driven by the wind in which the kinetic energy of a moving fluid is converted into mechanical energy by causing a bladed rotor to rotate
