Definitions
Scope 1 emissions refer to those generated on site. Examples are gasoline for vehicles, towngas for cooking, and leaked refrigerants from air conditioning.
Scope 2 emissions refer to those generated by off-site power plants. While the university is responsible for using electricity, it has no control over the conditions in the plant.
Scope 3 emissions refer to emissions emitted by someone else, but are influenced by university actions. Examples are employee commuting and university-sponsored air travel.
