The Kyoto Protocol was adopted as part of international efforts following which major environmental summit held in 1992?

• A. Earth Summit
• B. Montreal Summit
• C. Kyoto Summit
• D. Paris Summit

Answer: (A)

The question centers on which 1992 summit sparked the ongoing push for international climate cooperation that culminated in the Kyoto Protocol. The Earth Summit held in Rio de Janeiro, officially the United Nations Conference on Environment and Development, did just that. It produced key frameworks for global environmental action, notably the UN Framework Convention on Climate Change, which set up the institutional path for later agreements like the Kyoto Protocol to be negotiated and adopted under its umbrella. That connection is why the Earth Summit is the best answer. The Montreal event is tied to the ozone layer treaty, not climate, and the other two options aren’t the 1992 summit that led to Kyoto.
