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. Scott Morgan
