Depletion of stratospheric ozone by chlorofluorocarbons was addressed internationally by which landmark agreement?
- A Montreal Protocol, 1987 ✓
- B Stockholm Convention on POPs, 2001
- C Kyoto Protocol, 1997
- D Basel Convention, 1989
Correct answer: A. Montreal Protocol, 1987
Explanation
The Montreal Protocol (1987) phased out production of ozone-depleting substances such as chlorofluorocarbons and halons, and it is widely regarded as the most successful environmental treaty. The Kyoto Protocol addresses greenhouse gases and climate change, the Basel Convention controls transboundary movement of hazardous wastes, and the Stockholm Convention targets persistent organic pollutants. Distinguishing these treaties by their target pollutants is the tested point here.
