| Zusammenfassung |
| A basic requirement for any biochar offset methodology is for the carbon in biochar to be
stable and remain sequestered on centennial timescales. It is well known that a variable
component of most biochar is labile (degradable on annual/decadal timescales)
and hence only a proportion of total carbon in biochar provides long-term carbon
sequestration. This stable fraction of biochar is in the form of polycyclic aromatic
carbon (PAC) but small ring size compounds ( |
