US: Carbon Limit has announced the launch of CoolCrete, an additive designed to lower the temperature of concrete by over 10°C through advanced thermal emittance and enhanced solar reflectance. The company says that CoolCrete-treated concrete will help to tackle the urban heat island effect. By reducing the proportion of cement in concrete, it also lowers its CO₂ emissions by up to 40%. Licensed affiliates Bison Innovative Products and NCP Industries are set to incorporate CoolCrete in commercial and residential concrete products later in 2024.
