New production believed to be responsible for increasing levels of outlawed ozone-depleting chemical
At least 40-60% of the increase in emissions of a key ozone-depleting chemical reported last year can be traced back to sources in eastern China, atmospheric chemists have shown.
The observations appear to confirm suspicions that trichlorofluoromethane (CFC-11) is being manufactured in China in contravention of the 1987 Montreal Protocol, the international agreement to phase out CFCs.
