My blog is Carbon Neutral!

Iniziativa per minimizzare l'impatto ambientale dei nostri blog.
Credo che sia un'iniziativa molto interessante.
Funziona in maniera semplicissima. Si scrive un post sull'iniziativa, e si invia il link agli ideatori di questa iniziativa: Mach's grün.
Loro pianteranno un albero per il nostro blog che andrà a equilibrare le emissioni di CO2, necessarie a mantenere il blog. 
Qui è spiegato un pochino più in dettaglio come un blog crei emissioni di CO2 e perchè un albero aiuti a equilibrarle!
Potremo poi sfoggiare il carinissimo marchio "My blog is carbon Neutral" sul nostro blog!
How does a tree neutralise your blog’s carbon footprint?
How much carbon dioxide does your blog create? According to a study by Alexander Wissner-Gross, PhD, physicist at Harvard University and environmental activist, an average website causes about 0.02g (0,0008oz.) of carbon dioxide for each visit. Assuming an average blog gets 15,000 visits a month, it has yearly carbon dioxide emissions of 3,6kg (8lb.). This can mainly be tracked back to the immense energy usage from (mainframe) computers, servers, and their cooling systems.



How much carbon dioxide does a tree absorb? Unfortunately, no precise answer is possible. The carbon dioxide absorption of a tree can differ a lot. The amount of carbon dioxide that a tree can absorb depends on the type of tree, light exposure, length of the vegetation period, latitude, water balance, and the soil conditions. There are many different calculations for the saving potential of a tree. The assumed values vary between 10 and 30kg (20 and 70lb.) for a tree each year. It is certain however, that in its first two to three years a tree absorbs relatively little carbon dioxide. In the growth phase following this, the absorption rate increases rapidly. During this time, the tree safes a considerable amount of carbon dioxide. The absorption rate decrease again from the age of 18. The United Nations Framework Convention on Climate Change (UNFCCC) assumes a yearly absorption of one tree of approximately 10kg (20lb.) carbon dioxide emissions. “Make it green”, the environmental programme of kaufDA, is using a yearly absorption value of 5kg (11lb.) for its “My blog is carbon neutral” initiative. This is a very conservative calculation, ensuring that the neutralisation of each blog is achieved.

One tree neutralises the carbon dioxide emissions of your blog As demonstrated in the above calculation, the atmosphere can be relieved by an average of 5kg (11lb.) carbon dioxide every year by planting one tree. An average blog causes 3.6kg (8lb.) of carbon dioxide emissions. Consequently, a tree neutralises the carbon dioxide emissions of a blog. Since a tree lives for an average of 50 years, carbon dioxide emissions of your blog can be completely neutralised for this time period.

Make your blog carbon neutral! For free!

Being part of the initiative “My blog is carbon neutral” is an active contribution to help the environment! All you have to do is described here. Make it happen - make it green!
“My blog is carbon neutral” is an initiative, originally started in Germany by the “Make it Green” programme, that has the goal to reduce carbon dioxide emissions. We plant a tree for your blog and thereby neutralise your blog’s carbon footprint for the next 50 years! Everyone can make a small contribution to the environment. Every tree counts!

Alla prossima!
