Our History 

Created in 2005, the Leather Working Group was the brainchild of a group of well-known brands and leading leather manufacturers that came together to focus on sustainability within the leather industry.  

Our Founding Members included brands such as Adidas, Clarks, Ikea, Nike, Marks & Spencer, New Balance, and Timberland, as well as key leather manufacturing companies from across the globe. 

The cornerstone of the group is the LWG Leather Manufacturer Audit Protocol – first launched in 2006 to assess the environmental performance and practical capabilities of leather manufacturing facilities. Now on Version 7.0 of the protocol, the audit has grown in scope and depth to assess the most important areas of environmental impact within the manufacturing process. 

We also launched the LWG Trader Audit Protocol in 2015, in recognition that traders of leather material play an important part in the global leather industry. This protocol has the added benefit of further enabling traceability across the leather supply chain and ensures the security 

In 2017, we launched the LWG Chemical Management Module (CMM), designed to assess a leather manufacturer’s use, management and disposal of chemicals within their facility. The CMM is also designed to align with the ZDHC MRSL for leather, minimising duplicative effort for our members.  

Today is comprised of over 1000 members from across the supply chain and offers multiple certification standards for different stakeholders in the leather manufacturing industry.
