For example, in 2021, the U.S. emitted about 5.6 billion tons of CO 2 and other greenhouse gases. 1 A hectare of trees, meanwhile, might hold around 50 tons of carbon, equivalent to around 180 tons of CO 2 in the atmosphere. At this rate, it would take a little over 30 million hectares of trees to account for one year of American …
