Comment:
First and foremost, I would like to thank all of the fine folks at
ARB that have done such a wonderful job with the Natural and
Working Lands Climate Change Implementation Plan Concept Paper.
With that being said, I would like to encourage you all to consider
including in the future the GHG emission reduction potential of
biochar, which is a carbon-rich material produced from the
thermo-chemical conversion of biomass during gasification or
pyrolysis processes (i.e. bioenergy generation). Biochar is
currently a regulated soil amendment under CDFA's Food and
Agriculture Code (section 14513.5). 

Considering the need for developing new market opportunities for
biomass removed through tree mortality and agricultural residue
waste diversion programs, I am writing to express my support for
the consideration of biochar production and utilization as an
accepted management practice to promote greater GHG emission
reductions on natural and working lands across California. The
scientific literature supports the conclusion that charring biomass
results in changes in material properties of biochars that confer
greater persistence to mineralization than any other form of
organic matter that is commonly applied to soil (Lehmann et al.,
2015). Additionally, the results of a meta-analysis show that the
addition of biochar decreased N2O emissions from soils by an
average of 54 percent (Cayuela et al., 2014). In 2015, soil
management was responsible for 5.86 MMT CO2e or 17 percent of
agricultural emissions, of which N2O accounted for 96.75 percent of
all soil emissions in California. For more information on the GHG
emission reduction potential of biochar, see attached paper. 

I look forward to discussing this topic further at your earliest
convenience.
