Treatment of biogenic carbon content of construction products in Environmental Product Declarations (EPD)
12 January 2023
“Biogenic” carbon is sequestered through photosynthesis from atmospheric CO2 into biobased carbohydrates, and then incorporated into more complex molecules, for example into cellulose or lignin which are key components of trees or plant material. This biogenic carbon content is therefore sometimes called “sequestered carbon”. This Briefing Paper describes how biogenic carbon content is considered within an Environmental Product Declaration (EPD).
