Portland State University
OP-20: Employee Commute Modal Split

Institution's employees (faculty, staff, and administrators) get to and from campus using more sustainable commuting options such as walking, bicycling, vanpooling or carpooling, taking public transportation, riding motorcycles or scooters, riding a campus shuttle, telecommuting, or a combination of these options. 

Employees who live on campus should be included in the calculation based on how they get to and from their workplace. 

This credit applies to all institutions.

Institutions earn the maximum of 2 points for this credit by having all employees use alternative modes of transportation for getting to and from campus. Incremental points are awarded based on the percentage of employees that use alternative modes. For example, an institution for which 50 percent of employees use alternative modes and the other 50 percent drive alone would earn 1 point (half of the available points for this credit). 

See a scoring table in the STARS Technical Manual.

Sampling and Data Standards

Institutions may use a representative sample to gather data about employee commuting behavior. The South Coast Air Quality Management District provides guidelines on how to measure commuting behavior (pdf). 

This credit is scored based on the percentage of employees using alternatives to single-occupancy vehicle commuting (i.e. more sustainable commuting options). It is not required that the various transportation modes reported in the optional reporting fields total 100.
