This is great advice! There is no reason to do things that both save money and are good for the planet. It’s a nifty tool for making and keeping such pledges. In short, if you fail to keep your pledge it nicely asks you to donate money to a charity such as World Land Trust. So whether you keep your green resolution or not, the world will be a little bit better place.

Pledgehammer is something myself and a few friends opened just over a week ago. Would be great to hear feedback to it.
