Paris Agreement — Definition
Definition
The Paris Agreement stands as a landmark international accord, a legally binding treaty designed to address the pressing global challenge of climate change. Adopted by 196 Parties at the 21st Conference of the Parties (COP21) in Paris on December 12, 2015, it officially entered into force on November 4, 2016.
Its fundamental objective is to significantly reduce global greenhouse gas emissions and to limit the global temperature increase in this century to well below 2 degrees Celsius above pre-industrial levels, while simultaneously pursuing efforts to cap the increase at 1.
5 degrees Celsius. This ambitious target is rooted in scientific consensus, recognizing that exceeding these thresholds could lead to catastrophic and irreversible climate impacts.
Unlike its predecessor, the Kyoto Protocol , which imposed top-down, legally binding emission reduction targets primarily on developed nations, the Paris Agreement adopts a 'bottom-up' approach.
Central to this approach are Nationally Determined Contributions (NDCs). Each signatory country is required to prepare, communicate, and maintain successive NDCs that outline its climate action plans, encompassing mitigation (reducing emissions), adaptation (adjusting to climate impacts), and means of implementation (finance, technology transfer, capacity building).
The NDCs are not legally binding in terms of achieving specific targets, but the obligation to submit, update, and pursue them is legally binding, creating a framework of accountability and continuous improvement.
This flexibility allows countries to set targets appropriate to their national circumstances and capabilities, fostering broader participation.
Another critical element is the 'ratchet mechanism' or 'ambition mechanism.' This mandates that NDCs must be updated every five years, with each successive NDC representing a progression beyond the previous one and reflecting the highest possible ambition.
This mechanism is crucial for ensuring that collective efforts continually increase over time to meet the long-term temperature goals. The Agreement also establishes an enhanced transparency framework (ETF) for action and support, requiring countries to regularly report on their emissions and their progress towards achieving their NDCs, as well as on the financial, technological, and capacity-building support provided or received.
This framework is designed to build trust and confidence among Parties and to facilitate a global stocktake.
The global stocktake, conducted every five years starting in 2023, is a comprehensive assessment of the collective progress towards achieving the Agreement's long-term goals. It identifies gaps and informs countries in preparing more ambitious NDCs.
Furthermore, the Paris Agreement addresses climate finance, with developed countries reaffirming their commitment to mobilize $100 billion annually by 2020 (and extending to 2025) to support developing countries in their mitigation and adaptation efforts.
It also includes provisions for technology development and transfer, capacity building, and a dedicated mechanism for 'loss and damage' associated with climate change impacts, acknowledging that some impacts are unavoidable and beyond adaptation.
From a UPSC perspective, understanding the interplay of these mechanisms – NDCs, the ratchet mechanism, transparency, global stocktake, and finance – is paramount to grasping the Agreement's innovative and evolving nature.
