The new protocol includes a number of revisions that will continue to drive environmental stewardship improvement within the sector. The two most significant changes are the implementation of water usage measures and the inclusion of wastewater treatment outflow performance measures.
Through its work, the group has seen the LWG audit protocol accepted by many global brands and tanners as the most effective measure of the environmental performance of leather manufacturers. The system of rating processors has prompted several major footwear brands to set minimum ratings for their suppliers.
More than 50 tanneries have been audited under the protocol to date. The audits have yielded just 17 medal-rated tanneries. According to BLC, the performance by these tanneries demonstrates commitment above the norm to environmental stewardship:
