‘Supercooling’ material could drastically reduce carbon dioxide emissions and energy consumption associated with air conditioning units
A highly reflective cement could keep buildings cooler in hotter weather, alleviating the need for air-conditioning units. According to the researchers who developed the material, reflecting just 1% more of the sunlight that hits buildings and road surfaces worldwide would provide a planet-cooling effect equivalent to removing 44 billion tonnes of carbon dioxide from the atmosphere.
