What are NDCs?

NDCs are bottom-up climate strategies submitted every five years to the UNFCCC, focusing on short-term emission reductions and adaptation. While they allow countries to tailor plans to their specific capacities, they lack legal binding and sufficient ambition; current pledges would result in 2.7°C of warming. The document emphasizes the 2020-2030 period as the 'decisive decade' and highlights the 2023 Global Stocktake at COP28 as a critical moment for increasing accountability and ambition before the 2025 NDC updates.

• NDCs are designed as bottom-up strategies that allow countries to create climate plans suited to their unique circumstances and capacities, which helped facilitate the global agreement to target 1.5°C warming.
• NDCs focus on a shorter time horizon (5-10 years) compared to net-zero targets, which often aim for 2050. This is critical because the 2020-2030 period is the 'decisive decade' to prevent the worst climate impacts, and waiting until 2050 to achieve neutrality could exhaust the carbon budget.
• Two structural flaws hinder NDCs: they are not legally binding, meaning there are no sanctions for failure, and they are voluntary, allowing countries to set their own ambition levels. Consequently, current NDCs would only limit warming to 2.7°C, and G20 countries—responsible for 80% of global emissions—are failing to meet their targets.
• The 2023 Global Stocktake at COP28 is expected to increase government accountability for NDC commitments, serving as a formative period before the implementation of new NDCs in 2025.
• As of 25 September 2023, 153 updated NDCs have been issued. Climate Action Tracker reports that 65% of these updated NDCs contain stronger targets than the first round, though global emissions must be halved by 2030 to maintain the 1.5°C target.
