Leather shoes, despite not being the highest volume product, contribute significantly more to environmental impacts like acidification, eutrophication, and global warming compared to other shoe types. This sustainability research insight is drawn from a 2015 study published in Chalmers Publication Library (Chalmers University of Technology). Using Life cycle assessment (lca) combined with product flow analysis and material flow analysis., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize material selection and production efficiency for leather footwear to significantly reduce the environmental footprint of shoe consumption.
Leather footwear carries a disproportionately high environmental burden in Swedish consumption.

Key Findings
- 01Shoe consumption in Sweden increased by 20% between 2000 and 2010.
- 02Leather shoes accounted for up to 50% of the environmental impact in 2010, despite comprising 24% of consumption.
- 03Material production accounts for 80% of the total life cycle environmental impact.
- 04Leather, wool, nylon, aluminium, synthetic rubber, PET plastic, PU plastic, and viscose were identified as high-impact materials per kilogram.
Application
Design takeaway
Prioritize material selection and production efficiency for leather footwear to significantly reduce the environmental footprint of shoe consumption.
How to apply
When designing footwear, conduct a comparative analysis of the environmental impacts of different materials and construction methods, paying close attention to leather and other identified high-impact materials.
Project actions
- 01When researching materials for a design project, look beyond just cost and aesthetics to consider their environmental impact.
- 02Consider the entire life cycle of your product, from raw material extraction to disposal, not just the manufacturing stage.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Combines multiple analytical methods (LCA, PFA, MFA) for a comprehensive view.
- +Provides specific data on consumption trends and impact contributions for different shoe types.
- +Focuses on a real-world consumption scenario.
Limitations
It's difficult to get precise LCA data for every single material and manufacturing process. This study focused on a specific region and time period, so results might vary elsewhere.
Reliability & validity
The study's reliability is enhanced by using established LCA methodologies and a defined time frame. Validity is supported by the detailed breakdown of shoe types and impact categories, though the exclusion of shoe lifespan is a limitation.
Think critically
Given that material production is the largest contributor to environmental impact, how can design innovation focus on improving the sustainability of raw material extraction and processing, rather than solely on end-of-life solutions?
Design Principles
"Life cycle thinking must extend beyond material volume to consider the inherent environmental intensity of specific materials and product types."
Understanding the differential environmental impact of product categories, even within similar product types, is crucial for targeted sustainability efforts. Designers and manufacturers can prioritize material choices and production processes for high-impact items to achieve greater environmental gains.
What This Means for Your Design
Even though people buy fewer leather shoes than plastic ones, leather shoes cause much more pollution. This is because the materials and how they are made are worse for the environment.

Paragraph starter
Research indicates that material production is a significant contributor to the environmental impact of footwear, with leather shoes exhibiting a disproportionately high burden compared to other types. This highlights the importance of material selection in design, as choices like using leather can lead to substantial environmental consequences in categories such as global warming and acidification, even if the product is not the most frequently consumed.
