What you’ll learn

  1. A hall in Le BourgetPlace the 12 December 2015 adoption in the COP21 hall and separate binding treaty process from nationally determined pledge content.Paris is a UNFCCC treaty adopted at COP21, in force from 4 November 2016. Procedures bind; NDC numbers stay national; compliance is facilitative.
  2. The temperature lineRead Article 2's well-below-2°C / pursue-1.5°C aim beside adaptation, finance-flow alignment, differentiation, and the Article 4.1 pathway.Three aims, differentiated responsibilities, and a peak-then-balance emissions pathway operationalize the temperature goal.
  3. Nationally determined contributionsExplain NDCs as five-year, progressive national plans recorded publicly and pursued through domestic measures.Every Party files successive NDCs. Progression and highest ambition are required; delivery still depends on domestic policy.
  4. Stocktake and the gapConnect transparency and the five-year global stocktake to the known shortfall between pledges and Paris-aligned pathways — then open one country's NDC.Report, review, stocktake, update. Participation is wide; the emissions gap remains a domestic and collective problem.

Questions this course answers

When and where was the Paris Agreement adopted?

UNFCCC records adoption by Parties at COP21 in Paris on 12 December 2015. 4 November 2016 is entry into force; 22 April 2016 is the Earth Day opening for signature.

What is the Agreement's long-term temperature aim in Article 2?

Article 2.1(a) uses both figures in one aim: well below 2°C, and pursue efforts toward 1.5°C.

How often must each Party communicate a nationally determined contribution?

Article 4.9 requires an NDC every five years, informed by the global stocktake.

What does "legally binding" mean most carefully for Paris?

UNFCCC describes a legally binding treaty; Articles 4 and 13 create procedural duties, while NDC content is nationally determined and Article 15 is facilitative and non-punitive.

What is the global stocktake for?

Article 14 defines a periodic collective stocktake whose outcome informs updating and enhancing actions and support.

Why can near-universal participation still leave an emissions gap?

Decision 1/CP.21 already flagged insufficient intended contributions; later UNFCCC NDC synthesis reports keep finding combined pledges short of Paris-aligned pathways.
