Q94 (CGS/2026) Environment & Ecology › Climate Change & Global Initiatives

Consider the following statements as regards to the protection of ozone layers :

I. The Vienna Convention aims to protect the ozone layer.

II. The Montreal Protocol is recognized as the most successful inter-national environmental treaty.

Result
Your answer: —  Â·  Correct: C

Explanation

Both statements are correct. The Vienna Convention for the Protection of the Ozone Layer (1985) was the first global framework dedicated to the protection of the stratospheric ozone layer. It encouraged intergovernmental cooperation on research and monitoring.

The Montreal Protocol (1987), an auxiliary to the Vienna Convention, is widely recognized as the most successful international environmental treaty. It is the only United Nations treaty to have been ratified by every country on Earth (universal ratification). Former UN Secretary-General Kofi Annan famously described it as "perhaps the single most successful international agreement to date." It has been remarkably effective in phasing out nearly 99% of ozone-depleting substances (ODS) like CFCs, leading to the gradual recovery of the ozone (O3) layer.
