Leather Working Group provides a path to a more responsible and transparent leather supply chain through their audit standards. The LWG certification has been developed with input from key actors in the supply chain to promote best practice in a facility's performance across environmental, social and governance considerations.

The audit certification process assesses the environmental performance and compliance of leather manufacturing facilities (also known as tanneries). The standard is used to assess leather manufacturers on the following aspects: water and energy usage, solid waste and effluent management, air and noise emissions, traceability, health and safety, chemical management, restricted substances, compliance and chromium VI (CrVI) management.


Our chrome-free leather comes from the best region in all of Italy and historical tannery known for the highest quality of leather, excellence and expertise for this type of treatment.


The ancient tradition and culture of vegetable tanning was invented in the early 1900’s in Italy and has been a craft of trade for centuries. The tannery which we work with embraces this method as a more sustainable approach to leather production.
