Gold
85% to 100% in every critical section.
LWG certified leather comes from a tannery audited by the Leather Working Group. The audit scores how the facility handles energy, water, waste, chemicals and traceability, and rates it Gold, Silver, Bronze or Audited. It rates the factory. The finished product isn't assessed, and animal welfare isn't one of its sections.
Each section of the audit gets a score, and the overall rating is the lowest one achieved.

The leather manufacturer audit known as P7, launched in 2021. LWG has updated it since, most recently in May 2025.
