Study: Tropical forests worse carbon emitters than U.S. trucks and cars

Tropical forests emit more carbon each year than all of the cars and trucks in the United States, scientists said on Thursday, calling for greater efforts to stem forest loss and damage.

Almost 70 percent of tropical forest emissions are caused by degradation, a study in the journal Science said, measuring the less visible form of damage for the first time along with deforestation which has long been recognized as problematic.

“These findings provide the world with a wakeup call on forests,” the study’s lead author, Alessandro Baccini, a scientist with the U.S.-based Woods Hole Research Center, said in a statement.
