Carbon toe-prints or carbon footprints?

Nowadays, there's a lot of discussion about carbon footprints. One can choose the most climate-friendly diet, car or holiday destination by comparing the carbon footprints of various products and services. The term carbon footprint can be defined as "shorthand to describe the best estimate that we can get of the full climate change impact of something." It is possible to estimate the carbon footprint for anything: a service or a product, an item or an activity, a country or a municipality. Or for example for the 2010 World Cup: 2.8 million tonnes of CO2.

In CHAMP we are also trying to promote low carbon footprint project management. In the project most of the carbon emissions are produced by travelling. For this reason, we are aiming at reducing our carbon footprint mainly by using e-communication instead of having to travel. As we were calculating our emissions caused by travelling, it was quite interesting to see how far from each other the results of different carbon calculators were.

There are great differences between the many carbon footprint calculators one finds online, and sometimes it is hard to evaluate which calculator gives the most truthful answer. The results some of the calculators could even be called carbon toe-prints since many of them don't take into account all emissions or even miss out most of the emissions. If we take for example flying, a lot more information than just the distance to destination is needed. An accurate calculation is only possible if the type of the plane, number of the stops etc. are known. The same goes with direct and indirect emissions - they must both be noticed to calculate the true carbon footprint of something.

Many online carbon calculators are only rough estimates but can anyway give a conception of the total climate impact a certain activity or item has. It is almost impossible to measure a carbon footprint accurately, but at the same time it is an essential part of understanding the whole picture of climate change response.

Who's your World Environment Day hero?


Tomorrow, on June 5th, we are celebrating World Environment Day (WED) 2010. WED has been organized by UNEP since 1972 and is aimed to be the biggest, most widely celebrated, global day for positive, environmental action. As part of the 2010 International Year of Biodiversity, this year’s event will celebrate the incredible diversity of life on Earth under the theme Many Species. One Planet. One Future.

Last year, the topic of World Environment Day was climate change and the highlight of the celebrations was to launch the Climate Heroes. This year the Climate Heroes initiative has been broadened beyond just climate change-related advocates to include exceptional individuals advocating solutions for all environmental issues.

WED Heroes are individuals who inspire and motivate people to environmental actions by undertaking exceptional personal feats, high-profile expeditions, and other acts of environmental activism to demonstrate their commitment to the planet.

In the end, the WED heroes is a call for each of us to do what we can: from adopting the simplest habits like turning off running water when we are brushing our teeth, to organizing a public or workplace event for World Environment Day or even rowing across the Pacific Ocean, like a WED Hero Roz Savage did in 2009, and later walked 600 miles from London to Copenhagen for the UN climate conference.

See the World Wide WED here and find activities near you.
