The Leather Working Group (LWG) has released a comprehensive Life Cycle Assessment (LCA) report [1], conducted by Spin 360, analyzing the environmental impact of producing one square meter of finished leather. The report evaluates 50 leather products across six categories, including footwear, furniture, leather goods, and automotive upholstery, covering the entire production process from raw material sourcing to manufacturing.
The LCA report identifies key environmental contributors, such as raw material sourcing and post-tanning processes, and offers actionable insights to help stakeholders reduce their environmental footprint. The analysis focuses on several impact categories, including Global Warming Potential, Eutrophication, Abiotic Depletion, Water Use, Freshwater Ecotoxicity, and Water Consumption.
The report emphasizes the importance of a holistic approach to mitigating adverse impacts, highlighting that upstream processes, such as farming and slaughtering, are significant contributors to the environmental impact of leather production. However, core manufacturing processes, particularly the post-tanning stage, also play a crucial role in environmental impact, especially concerning abiotic depletion and freshwater ecotoxicity.
The report provides stakeholders with robust data to make informed, sustainable decisions and advance their sustainability goals. LWG-certified leather manufacturers are expected to utilize this data to minimize their environmental footprint, while brands and retailers can use these insights to make informed sourcing decisions.
The report outlines actionable measures to improve the environmental credentials of leather production, advocating for a comprehensive approach to reducing environmental impacts across all stages of production. By addressing these key areas, the leather industry can work towards a more sustainable and environmentally friendly future.
