Discuss the significance of the Global Stocktake mechanism under the Paris Agreement. How can the second Global Stocktake address the gap between pledges and implementation?

Under Article 14 of the Paris Agreement, the Global Stocktake (GST) is a review held every five years of the world's combined progress towards the Agreement's goals [1]. Countries set their own climate targets, so the GST is the main tool for raising ambition over time. Its second cycle starts in November 2026 [1]. It must move the focus from making new promises to delivering on old ones.

Significance of the Global Stocktake

• Accountability that respects sovereignty: the GST checks collective progress rather than singling out countries. Each country's targets (NDCs) stay its own, but the shortfall becomes visible [1].
• Ratchet effect: under Article 4(9), each new NDC must be informed by the GST's outcomes, so every review shapes the next round of targets [2].
• Agenda-setting power: the first GST (COP28, Dubai, 2023) called for transitioning away from fossil fuels, tripling renewables and doubling energy efficiency by 2030 [3].
• Equity and science: the GST covers mitigation, adaptation and finance. It is conducted "in the light of equity and the best available science", which gives developing countries a place to judge the support they receive [2].

The pledge–implementation gap

• Finance: the NCQG (COP29, Baku) commits developed countries to lead on only ≥US$300 bn a year by 2035. The larger US$1.3 trillion figure is just a call to "all actors" [4].
• Adaptation: developing countries need US$310–365 bn a year by 2035, but public flows were US$26 bn in 2023, down from US$28 bn. The Glasgow goal of doubling adaptation finance is off track [5].

How the second GST can bridge it

• Check delivery first: review missed goals such as the Glasgow doubling target before accepting new pledges [5].
• Set baselines and yearly paths: any pledge to triple adaptation finance needs a base year. UNEP's 2023 figure is one ready option [5].
• Agree common accounting rules: one shared definition of climate finance would make NCQG delivery checkable [4].
• Time the outputs for the next NDCs: the GST ends in 2028 [1]. Its findings should feed directly into the next round of NDCs [2].
• Put grants first for the vulnerable: private capital could add only about US$50 bn a year to adaptation [5]. Small island states and least developed countries therefore need public grants.

The GST is the part of the Paris Agreement that holds countries to their word, and its value depends on whether its findings are followed up. If the second stocktake measures delivery and not just announcements, in line with CBDR-RC and SDG 13, it can rebuild North–South trust and keep the 1.5°C goal within reach.
