Environmental Claim Validation

Environmental claim validations provide independent verification that products live up to their marketing claims. This kind of validation gives both manufacturers and their customers peace of mind.

Working together to protect the environment through environmental claim validations


UL's environmental claim validations help manufacturers communicate their products' environmentally preferable attributes clearly and credibly, equipping them with a powerful tool for differentiation in an increasingly cluttered marketplace. Environmental claim validations from UL include:

Recycled content

Validates the post-consumer, pre-consumer (post-industrial) or total recycled content of a product by means of auditing.

Byproduct synergy

Validates supply chain localization, material optimization, waste minimization and virgin material substitution achievements through active dialogue and working across facilities from diverse industries.

Rapidly renewable content

Validates that a product contains material that has a harvest cycle of less than 10 years. Examples of raw materials with a short harvest cycle include bamboo, corn and cork.


Evaluates a product’s recyclability through testing or auditing.

Paper-based products recyclability

Validates the recyclability of paper-based products through conducting repulpability tests and calculating recyclability rates based on the fiber content in sample products.

Volatile organic compound (VOC) content

Tests the VOC content of products in accordance with standard test methods and South Coast Air Quality Management District (SCAQMD) rules. Note these test are only conducted on liquid or aqueous solutions, such as paints, adhesives, sealants, coatings and other similar products.

Reclamation program/facility

Validates claims associated with reclamation programs or centers that a manufacturer might have to reclaim used products/materials by means of auditing.

Mold resistance

Tests certain products/materials for resistance to microbial growth in accordance with standard test methods, such as ASTM D3273, ASTM C1338 and ASTM G-21.

Landfill waste diversion

Validates a company’s waste diversion claims to a variety of levels through auditing.

Energy-saving power strips

Evaluates the energy savings of a power strip through testing.

Biobased content

Validates that a product contains biobased content through testing. Examples of biobased content include polylactic acid (PLA), crop residues and wood residues, among others.


UL Environment validates claims that a product does not contain formaldehyde, or formaldehyde precursors, using a combination of auditing raw material inputs and testing chemical emissions from the product. Qualifying products must also maintain UL GREENGUARD Gold certification to ensure no other harmful chemicals are emitted into indoor air.

Particulate, VOCs or mold and bacteria filtration efficacy for air filters

Evaluates and ultimately validates the performance claims regarding the percentage reduction of particulate, VOC, mold and bacteria levels for air filters.

Innovative claims

UL Environment sometimes provides validation of environmental claims that are new to market or do not have an existing UL protocol. Please contact 888.485.4733 for questions about claims not found on this page.


With UL's environmental claim validations, products get independent third-party confirmation of their compliance with various green codes, standards and procurement policies, including the LEED® Green Building Rating System, IgCC, GSA Advantage!®, ASHRAE 189.1 and more. This helps product visibility among key specifiers while driving marketplace demand.

Because these environmental claim validations are backed by UL, one of the world's most trusted names in product safety and certification, customers are empowered to make more informed purchasing decisions that help combat greenwashing.

Why UL

UL is one of the world's most trusted names in product safety and certification and delivers environmental claim validations that help manufacturers and brands demonstrate the sustainable attributes of their products to fulfill green building requirements.

“For us, the value UL Environment brings is to help us have trust in the recycle streams we’re utilizing, and then also convey that trust to our customers.”
