Cooling

More efforts needed

Tracking progress 2020

Energy demand for space cooling has more than tripled since 1990, making it the fastest-growing end use in buildings. Space cooling was responsible for emissions of about 1 GtCO2 and nearly 8.5% of total final electricity consumption in 2019. While highly efficient AC units are currently available, most consumers purchase ones that are two to three times less efficient. To put cooling on track with the SDS, energy efficiency standards need to be implemented to improve AC energy performance more than 50% by 2030. Together with improved building design, increased renewables integration and smart controls, this measure would cut space cooling energy use and emissions and limit the power capacity additions required to meet peak electricity demand.
