Environmental Impact

LWG Lifecycle Assessment (LCA)

Understanding the impact of leather made in Leather Working Group-certified facilities.

The Leather Working Group Life Cycle Assessment (LWG LCA) was developed to provide accurate, up-to-date insights into the environmental impacts of leather production. Its primary goal is to help stakeholders reduce environmental footprints and make informed, sustainable decisions. 

The analysis evaluates the environmental impact of producing one square meter of finished leather, with additional metrics available per kilogram. It examines key impact categories, including Global Warming Potential, Eutrophication, Abiotic Depletion, Water Use, Freshwater Ecotoxicity, and Water Consumption. 

Conducted by Spin 360, the LWG LCA delivers a comprehensive assessment of leather production, spanning 50 distinct products across six product families. These include chrome-tanned and glutaraldehyde-tanned leathers used in footwear, furniture, leather goods and automotive upholstery. The analysis covers the entire production process – from raw material sourcing to finished leather manufacturing, and incorporates globally sourced data. 

The LWG LCA outlines actionable measures to improve the environmental credentials of leather production. It is expected that Leather Working Group-certified leather manufacturers will utilise this data to minimise their environmental footprint. Meanwhile, brands and retailers can use these insights to make informed sourcing decisions and advance their sustainability goals. 

A summary of the findings can be downloaded here and the full LWG LCA report is available to LWG stakeholders via their user portal here.

Phase 1: Scope Definition & Tannery Engagement

In the first phase, we defined the study’s goal and scope, considering factors such as geographical origin, animal type, tanning technologies and the industries served (footwear, apparel, upholstery, etc.). 

Phase 2: Data Collection

From April 2022, we begin the data collection phase of the LCA study. This will draw on information about the raw material, energy usage, chemicals, water consumption, water and air emissions, and waste management.

Phase 3: Data Analysis

Once all data has been collected, Spin360 will aggregate all data, conduct thorough data analysis and produce an impact indicators report.

Phase 4: Reporting Results

The results of the LCA study will then be communicated to our membership, and data submitted to Higg for inclusion into the Higg Material Sustainability Index (MSI).
