Short answer
Designers and businesses should conduct thorough LCAs to evaluate the true environmental impact of their food supply chains, considering all stages from production to consumption, rather than relying on simplified metrics like distance alone.

Contrary to common assumptions, short food supply chains can sometimes have a greater environmental impact than longer ones due to factors beyond just distance, such as infrastructure and distribution methods. This sustainability research insight is drawn from a 2020 study published in Energies. Using Life cycle assessment (lca) with 428 food supply chains, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers and businesses should conduct thorough LCAs to evaluate the true environmental impact of their food supply chains, considering all stages from production to consumption, rather than relying on simplified metrics like distance alone.
Short food supply chains are not inherently more eco-efficient than long ones.

Key Findings
- 01On average, long food supply chains may generate less negative environmental impacts (fossil fuel energy consumption, pollution, GHG emissions) per kg of product compared to short chains.
- 02Eco-efficiency indicator values show significant variability across different types of short food supply chains.
- 03Environmental impacts are influenced by numerous factors beyond geographical distance, including supply chain infrastructure.
Application
Design takeaway
Designers and businesses should conduct thorough LCAs to evaluate the true environmental impact of their food supply chains, considering all stages from production to consumption, rather than relying on simplified metrics like distance alone.
How to apply
When designing or optimizing food distribution networks, use LCA tools to compare different chain lengths and logistical strategies, considering factors like transportation modes, storage, packaging, and energy use in distribution centers.
Project actions
- 01When researching sustainable food systems, don't just focus on local sourcing; investigate the entire journey of the food.
- 02Consider using LCA as a tool to compare different design options for food distribution.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes a robust methodology (LCA) for environmental impact assessment.
- +Analyzes a large sample size across multiple countries and food types.
Limitations
The specific types of food and the infrastructure in the studied EU countries might not perfectly represent all scenarios. The definition and categorization of 'short' versus 'long' supply chains can be subjective.
Reliability & validity
The study's reliability is supported by the use of a standardized LCA methodology and a large, multi-country sample. Validity is enhanced by comparing diverse chain types and acknowledging the influence of multiple factors beyond distance, though the specific definitions and data inputs for each chain could influence results.
Think critically
If shorter distances don't always mean better environmental outcomes, what other factors in the food supply chain have the most significant impact on sustainability, and how can designers influence these?
Design Principles
"Holistic supply chain assessment is crucial for genuine environmental sustainability."
This finding challenges the prevailing notion that shorter is always better for the environment in food systems. Designers and businesses aiming for sustainability need to consider a holistic view of the supply chain, including logistics, infrastructure, and operational efficiencies, rather than solely focusing on reducing physical distance.
What This Means for Your Design
Just because food travels a shorter distance doesn't automatically mean it's better for the environment. Sometimes, how the food is transported and stored along the way makes a bigger difference.

Paragraph starter
Research indicates that the assumption of short food supply chains (SFSCs) being inherently more environmentally sustainable than long ones is not always accurate. A Life Cycle Assessment (LCA) study of food chains in the EU found that longer chains can sometimes exhibit lower environmental impacts due to factors such as distribution infrastructure and logistics efficiency, which can outweigh the benefits of reduced travel distance. This suggests that a comprehensive, holistic analysis of the entire supply chain is necessary to accurately determine eco-efficiency, rather than relying solely on geographical proximity.
