Displaced Environmental Footprint

The displaced environmental footprint (outsourced environmental footprint) refers to the ecological impact generated outside the geographic territory where a product or service is consumed. It includes carbon, water, land-use, and biodiversity footprints associated with global supply chains.

Main Drivers

• Globalisation of trade
• Cost-based comparative advantages
• Lack of harmonised environmental standards

Concrete Examples

• Imported soy → Impact country: Brazil · Footprint: deforestation and virtual water · Magnitude: 50 Mha of forest converted (2000–2020)
• Textile cotton → Impact country: Pakistan · Footprint: blue water · Magnitude: 4,000 L per kg of fibre
• Lithium batteries → Impact country: Chile · Footprint: water footprint & brine extraction · Magnitude: 1.8 m³ per tonne of lithium carbonate equivalent (LCE)

Indicators and Metrics

• Footprint Displacement Index (FDI): percentage of the total footprint that occurs outside the consuming country.
• Water Dependency Index (WDI): measures the proportion of imported virtual water relative to total water footprint.

Mitigation Strategies

• Comprehensive supply-chain traceability
• Environmental and social certifications (Rainforest Alliance, Fairtrade)
• Responsible procurement policies (Green Public Procurement) prioritising products with lower displaced footprint
• Virtual-water and embodied-carbon labelling to inform end consumers

Measuring the displaced environmental footprint reveals the true impacts of consumption and is essential for designing sustainability policies that address the entire global value chain.
