- ‘In the 1970s it was established that CFCs were eroding the earth's ozone layer, and since then they have gradually been replaced by less harmful chemicals such as hydrochlorofluorocarbons and butane.’
- ‘Blowing agents such as chlorofluorocarbons, and to a lesser extent hydrochlorofluorocarbons, have been identified with the destruction of the earth's protective ozone layer.’
- ‘Many CFCs have been replaced with related materials known as hydrochlorofluorocarbons which reportedly do not interfere with the ozone layer.’
- ‘The hydrochlorofluorocarbons, or HCFC's, used today are a significant improvement.’
