Which feature is associated with the Paris Agreement on climate change?

• A. Uniform global emissions reductions for all countries.
• B. Nationally determined contributions and market mechanisms.
• C. Sector-specific phaseouts of greenhouse gases only.
• D. No international cooperation on climate.

Answer: (B)

The main idea being tested is how the Paris Agreement approaches reducing greenhouse gas emissions. The agreement is built on countries submitting their own emission reduction plans, called nationally determined contributions (NDCs), and on using market-based and other cooperative approaches to help reach those goals. This bottom-up setup means there isn’t a single global mandate forcing all countries to cut emissions by the same amount; each nation sets its own targets and timelines. It also encourages cooperation through mechanisms that can trade or transfer emission reductions, along with non-market ways to support action, making it a flexible, collaborative framework.

This is why the option about nationally determined contributions and market mechanisms best fits. It reflects the Paris Agreement’s emphasis on country-specific plans and on cooperative tools to meet those plans. In contrast, a uniform global reduction requirement would overlook the country-specific targets, and a focus on sector-only phaseouts or an absence of international cooperation would misrepresent the agreement’s inclusive, cooperative nature.
