Chlorofluorocarbons in sentence

12 examples of Chlorofluorocarbons in a sentence

When the Montreal Protocol called for the phasing out of CFCs, the chlorofluorocarbons implicated in the hole in the ozone layer, the risks were immense.
We did a great job with the Montreal Protocol to limit the production of chlorofluorocarbons, CFCs, because of their effect on the ozone layer.
Second of all, objectively terrible quantities of hairspray, and third, CFCs, chlorofluorocarbons, man-made chemicals that were used as propellant in aerosol spray cans.
The Protocol explicitly aimed at phasing-out substances such as chlorofluorocarbons (CFCs) – found in products such as refrigerators, foams, and hairsprays – in order to repair the thin gassy-shield that filters out the sun’s harmful, ultra-violet rays.
Much of this improvement is thanks to HFCs, which are excellent ozone-friendly alternatives to older chlorofluorocarbons, which have been phased out.
Many toxic substances are released into the environment, even some that are not toxic but nonetheless are highly damaging – for example, the chlorofluorocarbons that caused the Antarctic ozone hole (and which are now regulated).
To protect the stratospheric ozone layer, international agreements have been reached to ban the use and trade of the ozone-destroying chemicals called chlorofluorocarbons (CFC’s).
This builds on an impressive phase-out of older chemicals, such as chlorofluorocarbons and others, that has averted the equivalent of 135 billion tons of CO2 from entering the atmosphere, while accelerating the recovery of the ozone layer.
One model is the Montreal Protocol on Substances that Deplete the Ozone Layer, which has succeeded spectacularly in reducing levels of chlorofluorocarbons, highlighting the continued potential of inclusive multilateralism.
Then, when it was discovered that certain chemicals called chlorofluorocarbons (CFCs) were causing the depletion of ozone in the atmosphere, the same groups launched a nasty campaign to discredit that science, too.
Beginning with the 1987 Montreal Protocol, and over the course of subsequent decades, states reduced their use of chlorofluorocarbons to the point that the atmosphere is now expected to recover.
Chlorofluorocarbons, used as refrigerants, caused the ozone hole, but efforts to replace them gave rise to hydrofluorocarbons, which are dangerous greenhouse gases.
