CO₂ Emissions From Embedded Carbon in Chemicals (PNG)

FREE

 

When fossil feedstock is used, the fossil-based embedded carbon contained in chemicals and materials is emitted to the atmosphere at their end of life, assuming complete oxidation (e.g. through combustion or (bio)degradation).

When using CCU-based feedstock to replace the fossil feedstock, at the end of life, no additional carbon (or CO2, respectively) is emitted to the air because it was captured from the air (or from point sources) before through carbon capture. Only the electricity demand for CCU-based feedstock production causes CO2 emissions.
