The document discusses financing energy productivity improvements in the GCC countries. It notes that energy consumption and GDP growth are still closely linked in the GCC, and significant capital investments will be required to transition to higher energy productivity. It outlines four types of investments that can improve energy productivity: retrofits solely focused on efficiency; new buildings/facilities with above-average efficiency; investments shifting the economy toward less energy-intensive industries; and refurbishments including efficiency elements. It argues that maximizing efficiency investment requires specialized funds, growing ESCO markets, and standardizing processes, contracts, and measurement.
