UL's Standards contain the requirements used to investigate materials, components, products, and systems for determining the eligibility of the material, component, product, or system to use UL's Listing, Classification, or Recognition Mark, or other UL Mark that may be required.

UL Environment standards will establish the basis for identifying environmentally preferable products, based on environmental sustainability criteria associated with the product's manufacture, distribution, use, and eventual disposal. The requirements in UL Environment standards will be developed based on the life cycle stages of the associated products.
