On Friday, Sept. 6, the $100 discount for early registration ends for the 2013 Green Fleet Conference & Expo. The Conference is in Phoenix on Oct. 1-2.

The Green Fleet Conference offers attendees the opportunity to engage with other fleet professionals through a variety of networking events, and through educational workshops and sessions. The Ride & Drive Event adds to those sessions by giving attendees the chance to test drive some of the latest alternatively fueled and powered vehicles. Around 400 fleet attendees are expected to attend this year.

For the first time, the conference will include multiple tracks — commercial, government, and heavy-duty truck — so that attendees can get the most out of the educational sessions and speakers most relevant to their fleet.

This year will also boast one of the conference’s largest exhibit halls yet. At 70,000 sq.-ft., the hall will include Chevron’s Delo Educational Truck, among many other exhibitors. The University of Michigan Solar Car Team will also display its Quantum electric solar vehicle.

You can see the full list of exhibitors at they currently stand here.

Government fleet attendees also qualify for a per diem hotel rate of $105 per night if the room is booked before the Sept. 6 deadline.
