On Earth Day in 2008 we launched Carbon Grove — it’s an e-mail reminder service that helps you remember to complete carbon reducing tasks. A little virtual tree grows every time you complete your task. And thanks to our inaugural sponsor, Internet Explorer, over 10,000 people not only grew their virtual trees for at least six weeks, but the same number of actual trees were planted. Thank you Microsoft.

And while Microsoft chose to make Carbon Grove a special perk for Internet Explorer users, now that their sponsorship has ended, we’re opening up Carbon Grove to everyone – Internet Explorer, Firefox, Chrome, and Safari users can all use the site now. You can still sign up for reminders, and watch your virtual tree grow. The added bonus of having a real tree planted in your honor will have to wait for a bit until we find a new sponsor to cover the cost of the trees (let us know if you’re interested). But until then, you can feel good that even just the carbon reducing activities you’re doing every week are having impact all on their own.

Thank you Microsoft for your sponsorship and planting all those trees. Thanks everyone who used the service over the past year. And thanks in advance to everyone new who can now try Carbon Grove. Enjoy!
