Carbon footprint A carbon footprint has historically been defined by Championne as "the total sets of greenhouse gas emissions caused by an organization, event, product or person."[1] The total carbon footprint cannot be calculated because of the large amount of data required and the fact that carbon dioxide can be produced by natural occurrences. It is for this reason that Wright, Kemp, and Williams, writing in the journal Carbon Management, have suggested a more practicable definition: "A measure of the total amount of carbon dioxide (CO2) and methane (CH4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system or activity of interest. Most of the carbon footprint emissions for the average U.S. household come from "indirect" sources, i.e. fuel burned to produce goods far away from the final consumer.

La déforestation de la forêt amazonienne Nous avons reçu le 12 mars 2006 le mail suivant : bonjour, chose promise, chose du, je vous envois notre TPE + le diaporama ( que j'envoie dans un autre mail) sur la déforestation de la forêt amazonienne, j'espère que cela pourra aider à quelque chose !! bonne continuation, Amicalement anne-S. TPE de Anne-S. leepton06@netcourrier.com Le mot forêt possède plusieurs sens. Notre terre porte un grand nombre de forêts différentes. Nous allons étudier la forêt Amazonienne, pour nous cette forêt représente le poumon de la Terre, ce problème nous touche car cette forêt est immense, elle recouvre 7 millions de Km² soit 13 fois la France, et c'est une des plus grandes forêts mondiales de plus elle est très exploitée. Cette forêt disparaît chaque jour au profit des hommes. D'une part les paysans pauvres défrichent les terres, car ils ont été expulsés de leurs terres par de gros propriétaires, la surpopulation ou l'expansion des villes. · Elle empêche l'érosion causée par le vent et par l'eau I.

Water footprint Water use can mean the amount of water used by a household or a country, or the amount used for a given task or for the production of a given quantity of some product or crop. The term "water footprint" is often used to refer to the amount of water used by an individual, community, business, or nation. World water use has been growing rapidly in the last hundred years (see graph from New Scientist article[1]). From 1900 to 2000, water use for agriculture went from about 500 to 2,500 cubic kilometers per year, while total use rose from around 600 to more than 3,000 cubic kilometres per year. In the U.S, the typical single family home uses about 69.3 gallons (262 litres) of water per day (2008 estimate). [edit] The water footprint of an individual, community or business is defined as the total volume of freshwater used to produce the goods and services consumed by the individual or community or produced by the business. The water footprint of a country is related to what its people eat.
Les principales causes et solutions à la déforestation Footprint for Finance The international debt crisis that has roiled world markets in recent years has challenged long-held assumptions of how to best measure a country’s wealth and gage its economic stability. Monitoring social and economic variables alone, a growing number of investors now understand, is no longer enough to understand nations’ competitiveness. In a resource-constrained world, a critical component of economic success will be through careful biocapacity management. In October 2011, Global Footprint Network launched a two-year project with the United Nations Environment Programme Finance Initiative (UNEP FI) and leading financial institutions to investigate the links between ecological and financial risks at the country level, and introduce more ecologically informed risk analysis into the market. On November 19, 2012, the key findings of the E-RISC: A New Angle on Sovereign Credit Risk report were unveiled at an interactive event hosted by Bloomberg in London.
TAKE ACTION to stop Asia Pulp and Paper's logging in Indonesia's tiger rainforests For a decade, the threatened ramin tree species has been protected under Indonesian law, as well as the Convention on International Trade of Endangered Species, that was also designed to stop the ivory trade. However, Greenpeace's undercover filming of 2011 has revealed, the group says, that APP continues to log ramin trees in Indonesia, selling them to major global companies like Xerox, Walmart, Mondi, Countdown, Danone, Collins, Debden, Acer, Parragon, Barnes & Noble, and Constable & Robinson. As part of Greenpeace's investigation, samples from ramin logs found at APP's mill were sent to an internationally recognised expert in the area to confirm the samples were of the ramin species. Dr. Gerald Koch from the Institute of Wood Technology and Wood Biology, University of Hamburg, was able to do so effectively - and thus confirm APP's activities, Greenpeace say. The ramin trees aren't the only endangered species at risk because of APP's activities. APP denies the allegations.
Footprint for Cities Why track resource consumption and natural capital? Local governments succeed by helping all their residents live fulfilling lives, both today and in the future. The availability of natural capital, nature’s ability to renew and provide resources and services, is not the only ingredient in this vision. However, without natural capital – healthy food, energy for mobility and heat, fibre for paper, clothing and shelter, fresh air and clean water – such a vision is impossible. What’s in it for local governments? Ecological Footprint accounts allow governments to track a city or region’s demand on natural capital, and to compare this demand with the amount of natural capital actually available. To learn more about cities that have calculated their Ecological Footprint, we invite you to read our Case Stories. For example, Footprint accounts reveal the ecological demand associated with residential consumption, the production of value-added products, and the generation of exports.
Livre numérique Un article de Encyclo-ecolo.com. [titre du lien] Le livre numérique Le marché du livre numérique, aussi appelé livre électronique ou ebook, c'est moins de 1% des ventes de livres en France en 2010. Un livre électronique est un fichier électronique contenant un texte et des images numérisées. Rappelant que le marché du livre numérique ne représente que 30 à 40 millions d'euros, soit 1 % du chiffre d'affaires de l'édition, principalement au format CD/DVD qui plus est (et non pas en téléchargement, ce qui est moins écologique). On pourrait penser que le livre numérique est une aubaine pour l'environnement grâche aux économies de papier qu'il engendre Pourtant certains voient dans le livre numérique une mauvaise affaire car le livre numérique est avant tout un objet technologique dont la fabrication est gourmande en énergie et en métaux. small> De gauche à droite, Amazon Kindle, Bookeen Cybook Opus, Foxit eSlick </small> Livre numérique = La fin du papier ?

Water footprint and virtual water There is a relation between consumption by Dutch consumers and impacts on water systems elsewhere in the world. Many of the goods consumed in the Netherlands are not produced in the Netherlands, but abroad. Some of these goods, in particular agriculture-based products, require a lot of water during production. The total water footprint of the Netherlands is estimated to be about 2300 m3/yr/cap, of which 67% relates to the consumption of agricultural goods, 31% to the consumption of industrial goods, and 2% to domestic water use. This knowledge is relevant for consumers, government and businesses when addressing the sustainability of consumer behavior and supply chains.
