IRENA’s Climate Action Support 2025 report presents an in-depth overview of the Agency’s growing role in helping countries strengthen the energy components of their climate commitments under the Paris Agreement. The report emphasises that the latest cycle of nationally determined contributions, known as NDC 3.0, is a critical moment for countries to raise the ambition of their mitigation plans. These submissions are expected to reflect the outcomes of the First Global Stocktake, part of the UAE Consensus reached at COP28, which calls for stronger and more actionable pathways to decarbonisation. In this context, IRENA’s advisory role has become central to how countries integrate energy transition priorities into their updated climate commitments.
Support highlighted in the report includes guidance on shaping renewable energy and energy efficiency targets, identifying viable low-emission technologies, assessing mitigation options, improving grid flexibility, and strengthening national energy data systems. The report also stresses the importance of capacity-building efforts that empower governments to implement more coherent, technically sound, and forward-looking climate action plans.
A major theme of the report is the need to accelerate the global shift toward cleaner energy systems, especially the call emerging from the First Global Stocktake to significantly expand renewable power deployment and step up efficiency improvements before the end of the decade. As the custodian agency responsible for monitoring progress on these global objectives, IRENA notes that the new wave of NDC 3.0 submissions increasingly aligns with these priorities. Countries are placing greater emphasis on renewable energy expansion, efficiency gains, and the adoption of zero- and low-carbon technologies, reflecting a stronger convergence between national climate ambitions and the broader energy transition agenda.
