Which international agreement aims to reduce greenhouse gas emissions among countries?

• A. Montreal Protocol
• B. Paris Agreement
• C. Kyoto Protocol
• D. Basel Convention

Answer: (C)

This question tests understanding of international efforts to cut greenhouse gas emissions. The Kyoto Protocol was designed to set legally binding emission reduction targets for participating developed countries, with specific numeric goals and enforcement mechanisms to ensure compliance. That clear, target-driven structure makes it the most direct example of an agreement aimed at reducing greenhouse gases across nations. The Paris Agreement, while also about cutting emissions, relies on voluntary nationally determined contributions rather than fixed targets, reflecting a different approach. The Montreal Protocol addresses ozone-depleting substances, and the Basel Convention deals with hazardous waste. So the Kyoto Protocol is the best fit for this description.
