CFC What Happens

In 1987, the Montreal Protocol called for an end to the use of chlorofluorocarbons (CFCs), including trichlorofluoromethane (CFC-11) – the second most ozone-depleting gas. With decreasing emissions, concentrations of CFC-11 were expected to fall rapidly from 2010 onwards.

However, scientists have discovered evidence of increased emissions after 2013; in fact, they were 25 percent higher between 2014 and 2016 than between 2002 and 2012. Stephen Montzka, a Research Chemist at the US National Oceanic and Atmospheric Administration and co-author of the paper (1), says: “It was and is the most unexpected observation I’ve made during my 27 years of making global-scale measurements.

About the Author

Joanna Cummings

A former library manager and storyteller, I have wanted to write for magazines since I was six years old, when I used to make my own out of foolscap paper and sellotape and distribute them to my family. Since getting my MSc in Publishing, I’ve worked as a freelance writer and content creator for both digital and print, writing on subjects such as fashion, food, tourism, photography – and the history of Roman toilets. Now I can be found working on The Analytical Scientist, finding the ‘human angle’ to cutting-edge science stories.
