Plant a Tree With a Blog Post

KaufDA and the environment organisation I Plant a Tree started an initiative entitled "Mein Blog ist CO2-neutral" ["My blog is carbon neutral"]: 
For every blog that embeds their button, they will plant a tree.* The service is free and the idea is to neutralize 50 years worth of your blog's CO2 emissions.

All you need to do to participate is write a brief blog post, add a button of your choice to it, and write an email about your post to CO2-neutral[at]kaufda[dot]de.

* One tree per domain.
