What is the environmental footprint and how do companies calculate it?

The environmental footprint is a synthetic indicator that assesses the amount of natural resources used and the impacts on the ecosystem generated by an activity or organization. Unlike the carbon footprint, which focuses exclusively on greenhouse gas emissions, the environmental footprint offers a broader view, also considering factors such as land use, freshwater consumption, eutrophication, acidification, and toxicity. For companies, understanding this parameter means being able to objectively measure their ecological weight and therefore identify critical issues along the value chain. It is essential for companies to calculate and manage the environmental footprint, as it represents a strategic tool to reduce impact and improve their environmental resilience, regulatory compliance, and reputation.

In common language, the terms "environmental footprint", "ecological footprint" and "carbon footprint" are often confused, but they refer to distinct concepts. The ecological footprint measures how much biologically productive area is needed to regenerate the consumed resources and absorb the waste produced by an activity. It is expressed in global hectares (gha) and is useful for macro-scale assessments. The environmental footprint, on the other hand, has a more analytical and multidimensional approach, based on environmental indicators provided by the PEF (Product Environmental Footprint) and OEF (Organization Environmental Footprint) methods promoted by the European Union. The carbon footprint, finally, measures only the direct and indirect emissions of equivalent CO₂, and is one of the elements of the environmental footprint.

The calculation of a company's environmental footprint is based on standardized methodologies, including the Product Environmental Footprint (PEF) for products and the Organization Environmental Footprint (OEF) for company activities. Both are based on Life Cycle Assessment (LCA), a tool that enables the measurement of the environmental impacts of a product or service throughout all stages of its life cycle: from raw material extraction to production, distribution, use, and end of life. To proceed, one starts with the collection of company data (energy consumption, raw materials, waste, transportation, emissions), normalizes the data according to functional units, and applies the environmental coefficients provided by databases (e.g., Ecoinvent). The final result is a set of environmental indicators (CO₂, water consumption, acidification, ecotoxicity, etc.) expressed in scientific units.

Integrating the calculation of the environmental footprint into business processes represents a strategic investment. In the era of ecological transition, European regulations, primarily the Corporate Sustainability Reporting Directive (CSRD) and the ESRS standards, require companies to report their environmental performance in a transparent and standardized way. The environmental footprint is one of the most comprehensive tools to meet these obligations, but also to differentiate in the market, improve resource efficiency, attract green capital, and strengthen brand reputation. Furthermore, it allows anticipating regulatory and climatic risks, improving stakeholder dialogue, and accessing public incentives. In an increasingly sustainability-conscious competitive context, monitoring the environmental footprint becomes an integral part of solid ESG governance oriented toward creating shared and lasting value.
