Energy, Emission and Waste Changes Over Time
Carbon dioxide equivalent (CDE) or Equivalent carbon dioxide (CO2e) – An index to express the global warming potential of various greenhouse gases. It is expressed in terms of the mass of carbon dioxide that would have the same warming effect as the given quantity of the greenhouse gas. For example, methane has 25 times the global warming potential of carbon dioxide so one metric ton of methane would have 25 metric tons of carbon dioxide equivalent (MTCDE).
Full-Time Student Equivalent (FTE) – An index that expresses part-time and full-time student enrollment by applying a partial weight to the number of part-time enrollees.
Greenhouse Gas (GHG) – Gases known to trap heat energy within the Earth's atmosphere.
Heating Degree Days (HDD) – An index that calculates the sum of the differences between a given temperature, such as 65 degrees Fahrenheit, and the mean daily temperatures that fall below that given temperature over the course of one year. For example, a day with an average daily temperature of 63oF results in two HDD.
Million British Thermal Units (MMBTU) – A BTU is the amount of energy necessary to heat one pound of water one degree Fahrenheit.
Scope 1 Greenhouse Gas Emissions – Direct University emissions; includes emissions from the steam plant and direct transportation, such as staff work vehicles.
Scope 2 Greenhouse Gas Emissions – Emissions from purchased utilities; primarily from electricity providers.
Scope 3 Greenhouse Gas Emissions – Indirect University emissions; includes downstream and upstream emissions such as those produced by commuting and waste disposal.
