Currently all of CATA's fleet buses are CNG-powered and ridership has exceeded seven million passengers, the majority of riders being Penn State students.

In 1993, the CATA Board of Directions made a decision, to start running its buses using Compressed natural gas.

The fuel conversion became easy, as CATA operates its routes close to where natural gas is produced.

In 1996, CATA introduced their first fleet of natural gas buses built by Orion Bus Industries.

Following the completion of the Clean Natural Gas program, CATA continued to experiment more alternate fueling option, by joining with Penn State and Larson Transportation Institute.

[7] This bus was studied for a possibility to use Hydrogen as a fuel for public transportation in Penn State.

Four routes were created as part of the agreement: The Blue and White Loops (in conjunction with the school's colors), and the Red and Green Links (the latter of which is no longer in service).

[11] A special commuter service was added to the College Avenue Connector route west of Butz Street.

Some of the routes have been replaced with CATAGO microtransit service, including Bellefonte, Boalsburg, Pine Grove Mills, Pleasant Gap, and Cato Park.

[13] Tokens can be purchased using credit or debit cards, cash, or LionCash (only at the CATA Customer Service Center on Beaver Avenue).

[14][15] (15) (1) In the summer of 2009, Orlando, FL's Central Florida's Regional Transportation Authority (LYNX) donated 10 35' New Flyer buses to CATA.

[17] In January 2008, CATA officially received $1.4 million in federal funding earmarks through the Transportation/HUD Appropriations bill for the 2008 fiscal year.
