Celilo Group created a digital version of its Chinook Book tailored to Portland State University students and employees.
The app, funded by PSUs Institute for Sustainable Solutions, enables 33,000 students, faculty and other university staff to have access to discount vouchers in the book, which is geared toward environmentally progressive businesses around town.
Coupons can be redeemed at Bike Gallery, Hotlips Pizza, Ben and Jerrys and other merchants. The book also includes bike maps, articles and videos about sustainability themes and green-job opportunities.
Portland-based Celilo now publishes Chinook Books for Portland, Seattle, the San Francisco Bay Area, Denver and Minneapolis.
The company added smart-phone apps to supplement the coupon book in 2010.
