Delays in nationally determined contributions often reflect credibility efforts and not weakening ambition
Abstract
This Comment examines why many countries delayed submitting updated Nationally Determined Contributions after the 2023 Global Stocktake. We argue that postponements often reflect efforts to enhance credibility and align pledges with domestic policy, rather than a lack of ambition. Based on compliance reports and case studies, we identify financial, institutional, technical, political, and strategic factors behind delays. Addressing systemic barriers is essential to restore momentum and ensure high‑quality NDCs.
