Designer Nitipak Samsen has designed the Automated Tree-Rental for Emission Encaging Machine (ATREEM), which essentially allows you to purchase carbon credits from a tree. The gadget measures the growth of a tree, translating into how much carbon dioxide the tree has absorbed. The gadget is designed to highlight just how long it takes for our carbon dioxide emissions to be reabsorbed.
The device is more about awareness than being a practical method for charging people for their carbon dioxide emissions. However, the gadget is capable of charging credit cards using its swipe-card interface.
Fools and their money are soon parted. Not even trees can refrain from ripping them off.
