Measuring climate action beyond commitments: a nationally determined contributions implementation index for Africa

The Paris Agreement shifted global climate governance from a top-down to a bottom-up model, making countries directly responsible for implementing their Nationally Determined Contributions (NDCs). Yet global monitoring frameworks remain focused on ambition and emissions, overlooking the institutional, governance, and financial conditions that determine delivery. This omission is particularly acute in Sub-Saharan Africa, where climate vulnerabilities intersect with weak institutions, fragmented data, and limited financial resources. This paper applies the NDC Implementation Index, a multi-dimensional framework developed through participatory stakeholder engagement to assess implementation rather than ambition. The Index evaluates five components—Governance (30%), Measurement, Reporting and Verification (MRV) (25%), Mitigation (20%), Adaptation (15%), and Finance and Technology Transfer (10%)—and was co-designed with African stakeholders to ensure contextual relevance. Data from NDCs, National Communications, Biennial Update Reports, and National Adaptation Plans for 12 countries (Kenya, Ethiopia, Ghana, Zimbabwe, Tanzania, Côte d’Ivoire, Namibia, Uganda, Botswana, Sierra Leone, Zambia, and Nigeria) were analysed using standardized scoring protocols. Results show that governance is the strongest dimension, with Kenya, Zimbabwe, and Ghana demonstrating advanced frameworks. Mitigation shows moderate progress, while adaptation remains underfunded. MRV, Finance, and Technology Transfer emerge as the weakest link, exposing systemic inequities in climate finance accessibility. The study contributes conceptually by operationalizing implementation as a measurable construct; methodologically by offering a transparent, participatory index; and strategically by creating opportunities for peer learning. It concludes that robust institutions are necessary but insufficient without equitable access to finance and technology, and calls for the integration of the Index into national and global accountability systems.
