a) PCs at certain Departmetns b) Palm Pilot flight logs (AHEC) c) Spreadsheet Inventory d) CABS Drop-Down Menu Benefits: - Annual Updates - Immediate Computerized Data Entry - Less Labor Intensive - Orthographic Accuracy a) Encourage CABS Training b) Goal: One universally-accessible Web-based Inventory Separate “Air Travel” from “Travel” a) Flight Legs  Enhancing Precision b) Contractual Obligation to UNC Climate Commitment

a) Rail for Short Trips (less than 300 miles) - Magnetic Rail…still waiting Benefits - Less emissions - Avoid airport hassle - More productive use of time (Rail can be fun!)
