UL Environment’s Advisory Services helps companies translate environmental leadership into greater market share and increased profitability. Our experts engage with organizations to identify and capture market opportunities, manage risks, and reduce costs through their sustainability initiatives.

From establishing a sustainability strategy to validating your sustainability achievements and communicating your progress to the market, UL’s Advisory team is your trusted partner in sustainability.



Circular Economy
Moving from a linear economy mindset to a more sustainable, circular approach that eliminates waste and keeps materials in productive use can uncover significant hidden value. UL can provide businesses with tangible, meaningful and actionable steps today, while positioning them for leadership in the future through certifications and validations of circular economy approaches, advisory and performance management. Learn how UL can help companies on their journey to circularity.

Innovative Claims
Claim Validations provide assurance and confidence about the sustainability claims you are taking to market.  If your company has a unique sustainability product claim or program, UL can develop a custom protocol to validate those achievements.  This helps companies communicate their achievements without the risk of making unverified claims in the marketplace. Set yourself apart with first-to-market claims, backed by a reputable third-party like UL.

Zero Waste
Reducing waste and diverting waste from landfills is equal parts sustainability, and smart business. UL offers three landfill waste diversion claim validations to recognize companies that handle waste in environmentally responsible and innovative ways—from energy production via incineration to reuse, recycling and composting.

Greener Product Framework
Purchasers are driving demand for healthier, more sustainable products. As a result, manufacturers are evolving their product offerings to be more sustainable than previous versions, or more sustainable than their competitors. A Greener Product Framework can enable improvement of the sustainability footprint of products in a measurable and meaningful way. UL’s Advisory team can help companies establish a Greener Product Framework; evaluate adherence to the Greener Product Framework, or look at ways to embed sustainability into new product design at the early stages of product development.

Evaluation of Health-Based Risks in Supply Chains
UL can help retailers navigate regulatory risks and support their supply chains by developing custom monitoring and risk assessments, such as compliance to CARB Phase II formaldehyde limits.  UL is uniquely positioned with subject matter experts to advise on global regulations, and conduct testing and certification.
