Report on the Unexpected Emissions of CFC-11 (WMO-No. 1268)

World Meteorological Organization (WMO) - WMO, 2021

The Report was written by the Scientific Assessment Panel to the Montreal Protocol on Substances that Deplete the Ozone Layer. CFC-11 (CCl3F) was reportedly fully controlled under the Montreal Protocol since 2010. However, a 2018 scientific paper revealed that instead of decreasing, CFC-11 emissions were increasing. In reaction, the Protocol parties agreed to Decision XXX/3: Unexpected emissions of trichlorofluoromethane (CFC-11). This Report addresses: current and past observations of CFC-11 atmospheric abundances; information on the CFC-11 global and regional emission increase and subsequent ...

The Report was written by the Scientific Assessment Panel to the Montreal Protocol on Substances that Deplete the Ozone Layer. CFC-11 (CCl3F) was reportedly fully controlled under the Montreal Protocol since 2010. However, a 2018 scientific paper revealed that instead of decreasing, CFC-11 emissions were increasing. In reaction, the Protocol parties agreed to Decision XXX/3: Unexpected emissions of trichlorofluoromethane (CFC-11). This Report addresses: current and past observations of CFC-11 atmospheric abundances; information on the CFC-11 global and regional emission increase and subsequent decrease; changes derived for emissions of dichlorodifluoromethane (CFC-12, CCl2F2) and carbon tetrachloride (CCl4); estimates of CFC-11 banks (CFC-11 that has been produced but has not yet been emitted); scenarios of future emissions and atmospheric concentrations; and the impact on the stratospheric ozone layer of the anomalous enhancement in CFC-11 emissions.

Use of chlorofluorocarbons in hydrology : a guidebook

IAEA, 2006

Development of the chlorofluorocarbon (CFC) technique as a tool for dating groundwater has occurred over the past 20 years, and a number of research publications have documented its use in specific aquifers. This publication is intended to facilitate a comparative analysis of CFC and isotope techniques and a wider use of the CFC technique under appropriate conditions, by providing a description of its scientific basis, sampling and measurement methods, interpretation and limitations of data, and a variety of case studies.
