Which statement best describes the Paris Agreement established in 2015?

• A. A binding treaty requiring all parties to maintain global temperatures below 2°C
• B. A non-binding framework with nationally determined contributions
• C. An agreement focusing on global trade in climate technologies
• D. A protocol to phase out ozone-depleting substances

Answer: (B)

At its core, the Paris Agreement creates a flexible, country-driven approach to reducing emissions by using nationally determined contributions. Each country decides its own targets and how to achieve them, rather than having a single universal set of binding obligations. Because it’s non-binding in terms of hard enforcement, there isn’t a global mechanism that forces all parties to meet specific emission cuts. Instead, the framework relies on transparency and regular reviews to encourage higher ambition over time. Every five years, there is a global stocktake to assess collective progress and inform stronger NDCs for the next cycle. This structure—non-binding framework plus nationally determined contributions with periodic review—best describes how the Paris Agreement operates. The other statements don’t fit this structure. It isn’t a binding treaty that requires all parties to keep global temperatures below a fixed threshold, and while the agreement aims to pursue well below 2°C and ideally 1.5°C, there is no universal, enforceable temperature target binding on all countries. It also isn’t about trade in climate technologies, nor is it a protocol addressing ozone-depleting substances—the latter is the Montreal Protocol.
