The embodied carbon of buildings is estimated to count for 11% of global carbon emissions and 75% of a building's emissions over its entire lifecycle. [7] The World Green Building Council has set a target for all new buildings to have at least 40% less embodied carbon.
Carbon profiling [1] is a mathematical process that calculates how much carbon dioxide is put into the atmosphere per m 2 of space in a building over one year. The analysis has two parts that are added together to produce an overall figure that is termed the 'carbon profile': Operational carbon emissions [2] Embodied carbon emissions [2]
Embodied energy is the sum of all the energy required to produce any goods or services, considered as if that energy were incorporated or 'embodied' in the product itself. . The concept can be useful in determining the effectiveness of energy-producing or energy saving devices, or the "real" replacement cost of a building, and, because energy-inputs usually entail greenhouse gas emissions, in ...
The application of production-based emissions accounting is currently favoured in policy terms as it is easier to measure, [2] but it is criticised in the literature principally for its inability to allocate emissions embodied in international trade/transportation and the potential for carbon leakage.

GHG emissions which are produced during the mining, processing, manufacturing, transportation and installation of building materials are referred to as the embodied carbon of a material. [164] The embodied carbon of a construction project can be reduced by using low-carbon materials for building structures and finishes, reducing demolition, and ...
Secondary databases can offer significantly different emission values for the same process, activity or input (e.g., the embodied emissions of 1 metric tonne of coking coal). PCRs permit the use of secondary data for emission flows out of the control of the manufacturer creating the EPD (e.g., emissions from the upstream supply chain), and LCA ...
The introduction of zero-energy buildings makes buildings more energy efficient and reduces the rate of carbon emissions once the building is in operation; however, there is still a lot of pollution associated with a building's embodied carbon. [14] Embodied carbon is the carbon emitted in the making and transportation of a building's materials ...
