New NASA research shows that Earth's atmosphere contains an unexpectedly large amount of carbon tetrachloride (CC14), an ozone-depleting chemical that was banned worldwide decades ago. According to the study, global emissions of CCl4 average 39 kilotons per year—approximately 30 percent of peak emissions prior to its banning.
