Notre Dame tracks a number of metrics related to sustainability. These graphs represent the most prominent of those metrics: recycling, carbon emissions, and water use.
- FTE: Full Time Equivalent, a measure of the number of people the campus serves.
- MTCO2e (Metric Tons of Carbon Dioxide Equivalent): emissions of gases other than CO2 are translated into CO2 equivalents so that their impacts may be directly compared. One metric ton is equal to 2,205 lbs.
- GSF (Gross Square Foot): Measurement of indoor building space from outside wall to outside wall.
