Verification mark for biogenic carbon content

A verification process according to the internationally accepted standard ISO/IEC 17029 ensures the trustworthiness of the verified claim, here the biogenic carbon content, resulting in the statement "Biogenic carbon content per Total carbon content > 30% - 90%" in steps of 10%.

The verification date on the mark is the date where TÜV SÜD issued the verification statement. This date states as year and month. 

ISO 16220 specifies a method of determining the biobased mass content in plastics products, based on the radiocarbon analysis and elemental analysis.

ASTM D6866 is a standard test methods for determining the bio-based content of solid, liquid, and gaseous samples using radiocarbon analysis.

Either one of the standards will be used for the Biogenic Carbon Content Verification.

Biogenic carbon refers to all those which are stored in, sequestered by and emitted through organic matter. The most common biogenic feedstocks include trees, plants and soil, which absorb carbon as a natural part of their life cycle.

Biogenic carbon is mostly regarded as preferable to non-biogenic carbon, given the fact that it can be replenished more readily than its counterpart. When trees are fallen or plants cut down for use in biomass plants, they are generally replaced with new ones. This means that any emissions from their combustion are theoretically carbon-neutral, since a proportional amount of the greenhouse gas will be consumed by the organic matter which replaces them.
