Many people assume that buying an artificial Christmas tree is better for the environment than buying a real one, given that real trees are cut down en masse. But that's not the case. In fact, a 2009 study found that using an artificial tree for a period of six years is associated with more carbon emissions than putting up a real one each year. Taking into account greenhouse gas emissions, human health factors, and resource consumption, the study concluded that an artificial tree would have to be reused for more than 20 years for its impact to be "greener" than that of real trees bought annually.
