During the Middle Ages it was a common practice for the Church to sell indulgences. They were like a get out of jail free card for wealthy sinners. Today we have carbon offsets which are forgiveness for our environmental sins. Brigter Planet is offering to offset 350 pounds of carbon for anyone who displays this badge on their blog or website.
How does one offset carbon? Brighter Planet is doing so by investing in renewable energy projects, such as wind turbine generators. How does displaying this badge on my blog translate into an investment in renewable energy? What does it cost to offset 350 pounds of carbon? Oh ye of little faith. It helps spread the word about Brigter Planet and builds Google page rank for it’s website. They offset 350 pounds of carbon for me because they said so.
