Decarbonisation of buildings
Buildings have a significant impact on global greenhouse gas emissions and play a major role in contributing to climate change. According to the International Energy Agency (IEA), the building sector accounted for 39% of global CO2 emissions in 2019. The energy used for heating, cooling, lighting, and powering appliances in buildings is the primary source of these emissions.
Apart from operational carbon emissions, embodied carbon emissions from the production of building materials, construction, and demolition also contribute to the building sector's carbon footprint. For instance, the production of cement, a key ingredient in concrete, is responsible for approximately 7% of global CO2 emissions.
