2014 CNG progress

By 2014, virtually all of OSU's bus fleet had transferred from diesel to cleaner burning compressed natural gas. The motor pool fleet had been positioned to do the same with plans to lease additional vehicles as they become more competitively available from manufacturers, and Regents approved the purchase of a CNG station on campus that same year, which also offers considerable cost-savings.

The green transport movement on campus started small in 2010, when OSU Transit initially purchased nine CNG buses, a number that quickly grew after the first natural gas fueling station was added in 2011, thanks to OSU's partnership with Clean Energy.
