The goal of doubling the global rate of improvement in energy efficiency by 2030, agreed at COP28 as part of the UAE Consensus, is emerging as a key pillar for achieving a just energy transition. However, current progress falls far short of the required pace: while the target calls for a 4% annual improvement, recent figures barely reach 1%. This gap carries significant consequences, including increased demand for fossil fuels, higher energy costs, and reduced climate resilience.

Accelerating energy efficiency could reduce the need for new generation infrastructure, deliver annual savings of up to $2 trillion, and improve equity in energy access. The report identifies five priority areas—motors and appliances, buildings, transport, electrification, and behaviour—that could contribute up to one-third of the required savings.

In the buildings sector, two priority actions are highlighted: speeding up energy renovation of the existing stock and strengthening the enforcement of energy codes for new constructions. These measures are supported by initiatives such as Buildings Breakthrough and the Intergovernmental Council on Buildings and Climate, which bring together dozens of governments committed to a resilient, near-zero emissions built environment. Achieving meaningful progress requires a combination of professional training, one-stop renovation support services, and enhanced international coordination. The report also emphasises the need to redirect climate finance towards technical assistance that enables countries to implement robust policies in this sector.
