How green is your blog?

Emerald, baby!

Kidding. Slightly. You may have noticed a nifty little button pop up in the sidebar - this is what it's all about:

"According to a study by Harvard University, 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.).

How much CO2 can a tree absorb? The answer varies, but the assumed values vary between 10 and 30kg (20 and 70lb.) for a tree each year. 

One tree neutralises the carbon dioxide emissions of your blog."

So how do we get around to planting these magically neutralizing (or neutralising, as they say in Germany) trees?

"Just write a short blog post about our programme “My blog is carbon neutral” and include one of the buttons on your site (ideally in the sidebar). Send the link to your blog to and we plant a tree for you, neutralising the carbon dioxide emissions of your blog. The trees will be planted in the spring of 2010 by the Arbor Day Foundation."

There you go. Not that my blog is getting anywhere close to 15,000 visits a month, but still. When do we ever need an excuse to plant more trees?

PS: I got this from Summer at ...and this time, concentrate! She is pretty cool - she is all for planting trees.
