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 ...
An emissions factor is applied to fuel consumption data from DUKES. Some data are also collected from individual point sources at generation facilities. The emissions factors are UK specific factors obtained by sampling average UK carbon content of fuels. Road transportation: CO 2, CH 4, N 2 O: 3
Coal is by far the worst emitter, followed by natural gas, with solar, wind and nuclear all low-carbon. Hydropower, biomass, geothermal and ocean power may generally be low-carbon, but poor design or other factors could result in higher emissions from individual power stations.

The emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by bombarding with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis of minerals. xyloid coal. Also called lignite or brown coal.
Deforestation is a major source of greenhouse gas emissions. A study shows annual carbon emissions (or carbon loss) from tropical deforestation have doubled during the last two decades and continue to increase. (0.97 ±0.16 PgC per year in 2001–2005 to 1.99 ±0.13 PgC per year in 2015–2019) [136] [135]
