Depends on how you are routing the cable. If you are running the cable in air spaces such as through drop ceilings or in air ducts, you're required to run plenum rated. Plenum rated cable is just a cable with an outer jacket which if it catches fire doesn't emit toxic fumes.
If you're running the cable exposed to the environment, then you should run environmentally/outdoor rated cabling. Otherwise, you run the risk of a physical cable failure.
