Ecological footprint Potential of the Ecological Footprint for monitoring environmental impacts from natural resource use Analysis of the potential of the Ecological Footprint and related assessment tools for use in the EU’s Thematic Strategy on the Sustainable Use of Natural Resources Report to the European Commission, DG Environment EXECUTIVE SUMMARY May

The Ecological Footprint - Definition The Ecological Footprint measures how much biologically productive land and water area is required to provide the resources consumed and absorb the wastes generated by a human population, taking into account prevailing technology. The annual production of biologically provided resources, called biocapacity, is also measured as part of the methodology. The Ecological Footprint and biocapacity are each measured in global hectares, a standardised unit of measurement equal to 1 hectare with global average bioproductivity. This study only evaluated the EF methodology used at the national level (and did not evaluate subnational applications). Ecological Footprint (EF). 3

Environmentally Weighted Material Consumption (EMC)- Definition EMC is a weighted indicator of material consumption based on environmental impacts. EMC estimates the environmental impacts of materials throughout a product’s life cycle. The underlying data for the EMC overlaps with that of the Ecological Footprint to some extent but unlike the Footprint’s expression in a single spatial unit (global hectares), the EMC combines a set of specific impact indicators (e.g. CO2 emissions, land use) that are then aggregated using weighting factors. Environmental issues not captured by the Ecological Footprint are included in the EMC, including the human-health and eco- toxicity impacts of certain materials, and the issues of ozone depletion, eutrophication, and acidification. 4

Key recommendations: Ecological Footprint (National Footprint Accounts only) The following are key recommendations for EU institutions and policy makers to use in considering how to implement the Ecological Footprint within the current indicator framework. 1. Combine with complementary sustainability indictors. The Ecological Footprint is designed to measure a specific aspect of sustainability (i.e. human demand for renewable resources for production and consumption as compared to available biocapacity). It is not designed to comprehensively measure overall sustainability. Therefore, many aspects of sustainability are missing from the calculation that should be covered by complementary indicators.

Key recommendations: Ecological Footprint (National Footprint Accounts only) 2. Use within the Sustainable Development Indicator (SDI) framework. The Ecological Footprint should be used by EU institutions within the Sustainable Development Indicators (SDI) framework. The SDI framework consists of 155 indicators organised hierarchically to measure 10 broad sustainability themes. It was created by the SDI Task Force in order to monitor the implementation of the Sustainable Development Strategy and was adopted by the European Commission in The SDI framework currently lacks a measure of global carrying capacity, and the Ecological Footprint can provide a measure of biocapacity with respect to human demand. Thereby it could add an important missing element to the SDIs, specifically with respect to Theme 6 “Production and consumption patterns”. 6

L'impronta ecologica misura l'area biologicamente produttiva di mare e di terra necessaria per rigenerare le risorse consumate da una popolazione umana e per assorbire i rifiuti prodotti. Utilizzando l'impronta ecologica, è possibile stimare quanti "pianeta Terra" servirebbero per sostenere l'umanità, qualora tutti vivessero secondo un determinato stile di vita. L'ettaro globale (gha) è un'unità comune che quantifica la biocapacità della terra. Un ettaro globale misura la produttività media di tutte le aree biologicamente produttive (misurata in ettari) sulla terra in un dato anno. Esempi di aree biologicamente produttive comprendono terreni agricoli, foreste e zone di pesca,. Non includono deserti, ghiacciai, e l'oceano aperto. "L'ettaro Globale persona" si riferisce alla quantità di terra biologicamente produttiva e acqua disponibile per persona sul pianeta, ad esempio, nel 2005 c'erano 13,4 milioni di ettari di terra biologicamente produttiva e acqua a disposizione e 6,5 miliardi di persone sul pianeta. [2] Si tratta di una media di 2,1 ettari globali per persona. 7

Mappa del mondo dei paesi per impronta ecologica (2007) World_map_of_countries_by_ecological_footprint_(2007).png Mappa mondiale dei paesi colorata in base alla loro impronta ecologica nel 2007 (pubblicata il 13 ottobre 2010 dal Global Footprint Network). E' misurata con la quantità di ettari globali (pro capite) che sono "richiesti" dagli esseri umani del paese. Le tonalità più chiare indicano i paesi con impronta ecologica pro capite più bassa e quelle più scure per i paesi con un'impronta ecologica pro capite più ampia. L'impronta ecologica totale (ettari globali "richiesti" dagli esseri umani) è definito come somma di sei fattori: impronta terreni coltivati, pascoli, foresta, pesca, emissioni di anidride carbonica e di aree edificate. x = (ettari globali "richiesti" dagli esseri umani) / popolazione 8
