UL’s NSF and Institute of Electrical and Electronics Engineers (IEEE) certifications are voluntary, multi-attribute, life cycle-based environmental certifications. These certifications indicate that your product has undergone rigorous scientific testing, exhaustive auditing—or a combination of both—to prove its compliance with stringent, third-party environmental performance standards.

As an approved certifying body for a variety of industry standards, we set metrics for criteria in the following categories:

  • Materials
  • Energy
  • Manufacturing and operations
  • Health and environment
  • Product performance and use
  • Product stewardship and innovation
