Despite reports that global emissions of the potent greenhouse gas, HFC-23, were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values. As a result, they reported that they had almost completely eliminated HFC-23 emissions by 2017.
