  • Il termine “impronta ecologica” è stato concepito nel 1996 da  William Rees e Mathis Wackernagel. Dal 1999 il Wwf (Wild worldwide Found) periodicamente calcola, aggiornandola, l’impronta ecologica nel suo Living Planet Report. Nell’ anno  2003 Mathis Wackernagel e altri studiosi hanno dato l’avvio al Global Footprint Network, che ha l’obbiettivo di migliorare la misura dell’impronta ecologica delle varie nazioni (e quindi di tutto il pianeta) e di conferirle un’importanza similare a quella del prodotto interno medio lordo. Il Global Footprint Network collabora attualmente con oltre 22 paesi tra cui :Francia, Germania, Italia, Australia, Brasile, Canada, Cina, Finlandia, Svizzera, ecc., e con autorità locali, università, istituti di ricerca, associazioni, ecc..

  • The ecological footprint is a measure of the area needed to support a population’s lifestyle. This includes the consumption of food, fuel, wood, and fibres. Pollution, such as carbon dioxide emissions, is also counted as part of the footprint. The United States, China and India have the largest ecological footprints. Without knowing population size we cannot understand what this means about individuals’ ecological demands. Large populations live in China and India. In both territories resource use is below the world average. The per person footprint in the United States is almost five times the world average, and almost ten times what would be sustainable.

  • Very often, the term carbon footprint is confused with another term called ecological footprint. Carbon footprint only considers net greenhouse gases emitted, whereas ecological footprint is much more encompassing.

  • Ecological Footprint (Impronta ecologica)
  • Ecological Footprint
    • What is A Ecological Footprint?
    • The ecological footprint is a measure of human demand on the Earth's ecosystems. It compares human demand with planet Earth's ecological capacity to regenerate. It represents the amount of biologically productive land and sea area needed to regenerate the resources a human population consumes and to absorb and render harmless the corresponding waste.
    • Using this assessment, it is possible to estimate how much of the Earth (or how many planet Earths) it would take to support humanity if everybody lived a given lifestyle
  • Ecological Footprint
    • Depends from :
    • Energy consumption
    • Loss of biodiversity
    • Land consumption
    • Sea resources consumption
    • Land resources consumption
  • Distribution of population…
  • … and ecological footprint
  • … and ecological footprint per capita 2009
  • Ecological Footprint by region 2010 Earth Overshoot day: August 21 st : the day in which we exhaust our ecological budget for the year
  • Scenario 2010 Earth Overshoot day: August 21 st : the day in which we exhaust our ecological budget for the year
  • Carbon Footprint
    • What is A Carbon Footprint?
    • A carbon footprint is a measure of the impact our activities have on the environment, and in particular climate change. It relates to the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for electricity, heating and transportation etc. The carbon footprint is a measurement of all greenhouse gases we individually produce and has units of tonnes (or kg) of carbon dioxide equivalent.
  • Greenhouse Gases
    • Vapore acqueo
    • Anidride carbonica (CO 2 )
    • Metano (CH 4 )
    • Ossidi di azoto (N 2 O)
    • Gas fluorurati
    Atmospheric composition has changed in the past two centuries: all the main greenhouse gases have substantially increased
  • Human activities have changed the composition of the atmosphere since the pre- industrial era
  • Temperature Warmest 12 years: 1998, 2005, 2003, 2002, 2004, 2006, 2001, 1997, 1995, 1999, 1990, 2000
  • The effects of the warming are visible also in the Arctic sea ice cover Arctic sea ice area decreased by 2.7% per decade (Summer: -7.4% per decade)
