Huella material (Material Footprint)

The material footprint (MF) is an indicator that measures the total amount of natural materials (biomass, fossil fuels, metallic and non-metallic minerals) extracted globally to satisfy the final demand of a country, sector or product.

Unlike traditional indicators that only account for direct domestic consumption, the material footprint includes the indirect extractions embodied in imports, offering a complete view of the physical impact of consumption.

This indicator reveals the true level of pressure that an economy exerts on the planet's resources. Reducing it is a central objective of the circular economy, the 2030 Agenda (SDGs 8, 12 and 15) and the European Green Deal.

Origin and conceptual framework

The concept of the material footprint emerged in the 1990s in the field of environmental accounting and ecological economics, in order to overcome the limitations of the Domestic Material Consumption (DMC) indicator.

While DMC only accounts for national extractions and net physical imports of materials, the material footprint incorporates the entire global supply chain, from extraction to production and transport.

In 2015, the United Nations adopted the material footprint as an official indicator of Sustainable Development Goal 8.4 and target 12.2 (improving global resource efficiency and decoupling economic growth from environmental degradation).

The indicator is expressed in tonnes per capita or relative to GDP (tonnes per unit of GDP), to measure the material intensity of the economy.

Relationship with other indicators

The material footprint complements other environmental indicators. While the carbon footprint measures emissions, the material footprint quantifies the physical pressure on the Earth system, adding a tangible dimension to sustainability analysis.

Global and European trends

According to the UNEP International Resource Panel (Global Resources Outlook 2024), global material extraction reached around 106 billion tonnes in 2020 and has more than tripled since 1970, with projections of continued growth towards 2060 unless resource efficiency improves.

According to Eurostat, the European Union's material footprint per capita is in the order of 14 tonnes, well above the level generally considered sustainable. Spain stands at a broadly similar level. The sectors that contribute most are construction, food, energy and mobility, which together account for the bulk of total material extraction.

Policies and reduction strategies

The EU Circular Economy Action Plan (2020) and the sustainable production and consumption agenda drive measures to reduce the material footprint through:

• Ecodesign and extending the useful life of products.
• Reuse, repair and remanufacturing.
• Substitution of virgin materials by recycled ones.
• Improving the efficiency of industrial processes.
• Promoting circular business models (servitisation, sharing economy).

In Spain, the Spanish Circular Economy Strategy 2030 sets a target to reduce the material footprint by 30% relative to 2010, supporting the dematerialisation of economic growth.

Practical applications

At national level

It makes it possible to assess whether GDP growth is accompanied by an increase or a reduction in resource use. An absolute decoupling (economic growth with lower material use) indicates real progress towards sustainability.

At company level

Organisations use the material footprint to:

• Measure the use of raw materials across their supply chains.
• Prioritise recycled or low-impact materials.
• Integrate circular economy criteria into their ESG reporting and life cycle assessment (LCA).

At sector level

Sectors such as construction or electronics use the material footprint to identify opportunities for mass reduction, material substitution and efficiency improvements.

Methodologies and calculation tools

Calculation requires data on physical flows and input-output matrices. Recognised methodologies include:

• UNEP Global Material Flows Database
• EXIOBASE (European multiregional database)
• OECD Material Resources indicators
• Eurostat Economy-Wide Material Flow Accounts (EW-MFA)

At corporate level, the indicator can be integrated into environmental management software and LCA tools (such as SimaPro or OpenLCA), combining it with carbon and water footprints for a holistic approach.

Importance for the circular economy

Reducing the material footprint means:

• Optimising resource use throughout the life cycle.
• Promoting the use of secondary materials from recycling.
• Designing repairable and dismountable products.
• Avoiding planned obsolescence.
• Minimising waste and landfilling.

The lower the material footprint, the higher the circularity of the production system. This indicator is therefore key to measuring real progress towards an economy decoupled from resource consumption.

Challenges and limitations

1. Data availability: obtaining coherent, up-to-date information on global material flows remains a challenge.
2. Methodological complexity: multiregional input-output models require significant computing capacity and standardised databases.
3. Shared responsibility: a country's material footprint also depends on the production practices of its trading partners.
4. Global inequality: developed economies externalise part of their material footprint to exporting countries.

Overcoming these challenges requires international cooperation, supply chain transparency and statistical harmonisation.

Innovation and digitalisation

The transition towards real-time measurement of material flows relies on:

• Blockchain platforms to record movements of raw materials and recycled products.
• IoT systems to track materials in factories and warehouses.
• Digital twins that simulate the material efficiency of industrial processes.
• Artificial intelligence to forecast demand and optimise material reuse.

These tools support traceability, verification and data-driven decision-making.

Impact on industrial and fiscal policy

Governments can use the material footprint to design:

• Taxes on the extraction of virgin resources.
• Fiscal incentives for the use of recycled materials.
• Green public procurement, prioritising products with a low material impact.
• Environmental labelling schemes that inform about the material intensity of consumer goods.

At company level, this indicator is increasingly integrated into sustainability reporting (CSRD) and into the EU green taxonomy criteria.

Towards dematerialisation

Several economies show that dematerialisation is compatible with economic growth when it is driven by innovation and smart regulation. Countries with advanced circular economy strategies have managed to stabilise or reduce their material intensity through resource efficiency, ecological taxation and advanced recycling, demonstrating that decoupling growth from resource use is achievable.
