What are Nationally Determined Contributions? Why Do They Matter?
Nationally Determined Contributions (NDCs) are the cornerstone of the Paris Agreement and essential for achieving its long-term goals. NDCs represent each country's commitment to reducing national emissions and adapting to the impacts of climate change. Article 4, paragraph 2 of the Paris Agreement requires each party to prepare, communicate, and maintain successive NDCs and to pursue domestic mitigation measures to achieve these contributions.
NDCs are submitted every five years to the UNFCCC secretariat. The next round is due in February 2025, with subsequent updates every five years thereafter (2030, 2035, and so on). NDCs outline specific targets for reducing greenhouse gas (GHG) emissions, strategies for adapting to climate change, and timeframes for implementation.
As the name suggests, NDCs are tailored to each nation's unique circumstances, capabilities, and priorities. However, developing countries face challenges in updating their NDCs without sufficient financial and technical support. In this regard, a robust NCQG that reflects their needs is critical to ensuring their participation in meeting global climate goals. Without sufficient resources, the risk of failing to align their NDCs with the 1.5°C target becomes significant.
Amidst the criticism towards NCQG during COP29, several countries announced enhanced net-zero policies as part of their commitments, such as:
- UK: Targeting an 81% reduction in emissions by 2035
- Brazil: Aiming for a 59–67% reduction by 2035
- Canada: Committing to a 40–45% reduction by 2035
- Mexico: Pledging to achieve net zero by 2050
- Türkiye: Setting a net-zero target for 2053
If anything, decarbonisation is becoming a driving force in both existing and emerging legislation, supporting the global transition to address the realities of climate change. In the coming year, an influx of climate-focused legislation is anticipated as part of updated NDCs, leveraging legal tools to aid mitigation, adaptation, and resilience efforts.
