Carpet padding minimizes wear and provides warmth and comfort. It also acts as a moisture and dirt barrier and compensates for inconsistencies in sub-flooring.

Currently, sustainable carpet padding choices include nylon, natural and recycled wool felt (available without pesticides or glues), natural jute fiber, polypropylene felt and rag pad, and recycled content padding. Recycled-content carpet padding is available in several types, including old padding from reclaimed carpet fibers and many commercial and industrial flooring materials contain recycled tire rubber or tire cord. Recycled content padding is priced competitively.
Some rubber flooring materials are suitable for both exterior and interior applications. Some of the recycled-content commercial and industrial flooring products have residential applications in exercise rooms, laundry rooms, entryways or for exterior stairs and outdoor walkways.
LEED points: possibly EQ Credit 3 - Construction IAQ Management Plan and EQ Credit 4.3 - Low-emitting Materials, MR Credit 6 for rapidly renewable materials or MR Credit 4 for recycled content materials.
