This is very exciting! There is a program called "My Blog is Carbon Neutral" that will plant a tree to offset the carbon emissions of a blog!
According to the website:
“My blog is carbon neutral” is an initiative, originally started in Germany by the “Make it green” program, that has the goal to reduce carbon dioxide emissions. We plant a tree for your blog and thereby neutralize your blog’s carbon footprint for the next 50 years! Everyone can make a small contribution to the environment. Every tree counts!
I am proudly sporting my new button on the right side of the blog. I hope everyone with a blog takes the time to do this!
