How does the Paris Agreement structure nationally determined contributions (NDCs) and the warming goal?

• A. Each country submits its own emissions reduction pledge (NDCs); the goal is to limit warming to well below 2°C, with efforts toward 1.5°C.
• B. A single global target applies to all countries; goal is to limit warming to 3°C.
• C. Countries must eliminate all emissions; goal to keep warming at 0°C.
• D. Only developed countries submit NDCs; goal to keep warming below 2.5°C.

Answer: (A)

The main idea being tested is that the Paris Agreement uses a bottom-up setup: each country defines its own pledge (its NDC) and the global goal is a temperature limit, not a single universal target. Countries prepare and submit their NDCs based on national circumstances, capabilities, and costs, and they’re expected to strengthen these pledges over time. The overarching warming goal is to keep global warming well below 2°C above pre-industrial levels, with efforts toward limiting it to 1.5°C. This framework isn’t a single global target applied to everyone, and it isn’t a mandate for all emissions to be eliminated, nor does it restrict NDCs to just developed nations. Instead, all countries participate by declaring their own ambitious contributions and periodically updating them, with a transparent system to track progress and a global stocktake every five years to raise ambition.
