In a study focusing on buildings in Mazandaran Province, Iran, researchers aimed to calculate the carbon footprint of concrete residential structures from construction to operation. Using measurements and data from a specific building in Babolsar, Iran, they estimated the amount of carbon produced by the materials used in construction and the energy consumed during building operation. Results showed that the construction of the concrete building produced 464 kg of carbon per square meter, with an additional 18.5 kg per square meter per year during operation. Furthermore, the energy consumed during the building's operation led to the production of 69 kg of carbon per square meter per year.
