Leather Manufacturers can join the group by having an LWG audit conducted by an approved auditor, LWG audits/membership remain valid for 24 months depending on the award. The audit generally takes 2 days on-site and is a comprehensive evaluation of a leather manufacturer’s environmental credentials. The audit is conducted against the LWG's Protocol and if the leather manufacturer performs well they achieve a medal rating and are promoted on the LWG website. The audit is also recognised and favoured by dozens of Global Brands.
Leather Working Group audited tanneries can be found globally and represent 20% of the world’s production of leather.
The LWG Assessment Protocol for Traders of part-processed material has been developed and refined over two years as the natural progression to allow part-processed material trader LWG members to fully engage in the LWG Programme.
