Leather Working Group is working to drive measurable change through the LWG Audit Standards.

LWG Audit Standards are designed to provide transparency and accountability within the leather supply chain. Our flagship audit standard, the LWG Leather Manufacturer Audit was first launched in 2005. Since then, we've launched additional audit protocols to further connect up different actors in the value chain and deliver maximum impact.

LWG Trader Audit Standard

Available since 2016, the LWG Trader Audit assesses the environmental impact of traders of raw and part-processed material, as well as finished leather. The standard also helps to facilitate traceability through the complex leather supply chain. The audit takes place over one day on site and the certification is valid for 12 months.

LWG Commissioning Manufacturer Audit Standard

Launched alongside the subcontractor audit in 2020, the LWG Commissioning Manufacturer Audit assesses the performance of companies that buy leather and commission subcontractors to perform all manufacturing operations on the material, before selling it on. These companies buy their own material for processing, but do not complete any operations themselves, instead using a series of LWG-certified subcontractors. The LWG Commissioning Manufacturer certification is valid for 24 months.
