What global climate agreement was established in 2015?

• A. The Kyoto Protocol
• B. The Montreal Protocol
• C. The Paris Agreement on Climate Change
• D. The Copenhagen Accord

Answer: (C)

The main idea here is recognizing the major international climate treaties and when they were established. In 2015, a landmark agreement was reached in Paris that created a universal framework for climate action. It sets the goal of keeping global warming well below 2°C above pre-industrial levels, with efforts to limit to 1.5°C, and requires all countries to put forward and regularly update their own nationally determined contributions. The Paris Agreement also emphasizes transparency, regular review, and financial support for developing countries. Although it was adopted in 2015, it only entered into force in 2016 after enough countries ratified.

This distinguishes it from other options: the Kyoto Protocol was adopted in 1997 and focused on binding targets for developed countries; the Montreal Protocol dates to 1987 and targets ozone-depleting substances; the Copenhagen Accord was a non-binding political agreement from 2009.
