Carbon Sequestration Sample Clauses

Carbon Sequestration. The mega-fire phenomenon has turned California’s forests into carbon emitters rather than carbon sinks. Well-managed forests provide a significant source of stable carbon storage. The Parties will manage for carbon sequestration by thinning dense stands and undergrowth and promoting growth of large trees, which provide hundreds of years of carbon storage. The Parties will work with experts like the California Air Resources Board to establish forest-specific carbon accounting techniques to incentivize stable carbon storage.

Carbon Sequestration. Carbon sequestration is “the capture and secure storage of carbon that would otherwise be emitted to or remain in the atmosphere.”90 Carbon sequestration includes ocean sequestration, sequestration by terrestrial ecosystems (soils and vegetation), and injection in geological formations. ▪ Terrestrial biomass quantity, location, and change, including agriculture and forest lands ▪ Carbonaceous gases and aerosols ▪ Marine productivity, such as chlorophyll concentrations Carbon sequestration is considered a promising means to mitigate the emissions of carbon from major industrial processes, including the energy sector. DOE, USDA, and other organization are actively pursuing carbon sequestration as a means to address climate change. Of the three major types of carbon sequestration, sequestration by terrestrial ecosystems has the greatest potential for application of NASA data and models. 90 Carbon Sequestration Research and Development, Office of Science and Office of Fossil Energy, U.S. Department of Energy, December 1999. Currently, the NASA Carbon Management Program Element has promoted several projects and partnerships on carbon management. The energy sector is related since it is one the largest generators of CO2 and other GHGs.

However, carbon sequestration is more closely tied to the goals of CCSP, which lists new carbon sequestration technologies as one of its key research needs, and CCTP, which has capturing and sequestering CO2 as one of its five research initiatives. The NASA Carbon Management Program Element has promoted projects related to carbon sequestration in partnership with other government agencies. While it is a key area for the energy sector in terms of response to carbon emission mitigation, carbon management solutions are generalized and not specific to the energy sector. 91 NASA-CASA Project, CASA-CQUEST Viewer, ▇▇▇▇://▇▇▇.▇▇▇.▇▇▇▇.▇▇▇/sge/casa/cquest.html.

Carbon Sequestration. Recalcitrant organic carbon that forms during the production of biochar by pyrolysis is resistant to decomposition by soil microorganisms, allowing the carbon to remain sequestered from the atmosphere for hundreds to thousands of years. Thus the effects of a biochar soil amendment on carbon sequestration can be determined through measurements of recalcitrant organic carbon in the soils. For this field trial, total organic carbon in the treatments and soil samples was analyzed (Tables 3.3a and 3.6.2a). The local soil testing lab did not have the abilities to quantify various fractions of total organic carbon (including recalcitrant). As such, the analysis and discussion of carbon sequestration for the field trial considers the total organic carbon added to the soil in the treatments and the amount of total organic carbon [i.e. the soil organic carbon (SOC)]. Comparisons of SOC among treatments and the control over time were used to identify potential changes to carbon sequestration due to biochar. The total organic carbon (in tons/acre) applied to the soil in the field trial (i.e., in the biochar, compost and mix treatments) was calculated by multiplying the measured percent organic carbon content (reported in Table 3) of the biochar (59.5%) and compost (23%) by the application rate 10 tons/acre. These amounts were combined to estimate the mix treatment which was 10 tons/acre each of biochar and compost. SOC was measured by the Soil Control Lab from the collected soil samples. Percent SOC is calculated by weight, meaning that small changes in bulk density (e.g., 1-2%) can affect the SOC percentages. The analysis of SOC took into account this effect of bulk density by converting the SOC percentages reported by the lab to tons/acre-6" using the measured bulk densities (g/cm3) for the same samples. Bulk density measurements were only taken in the fall of each year. As such, SOC in tons/acre-6” was calculated for fall 2012, 2013 and 2014. SOC was calculated for 6” soil depths (i.e., in units of tons/acre-6”) because this corresponded to the depth-interval of soil sampling. The following equation was used: SOC (tons/acre-6”) = (% SOC/100) * Bulk Density (g/cm3) * 758 The conversion factor of 758 for a 6” soil layer depth was derived as follows (▇▇▇▇▇▇▇ 2011, p. 32): tons/acre-6” = g/cm3 * 1 kg/1000 g * 2.204622622 lbs/kg * tons/2000 lbs * 16.38706 cm3/in3 * 144 in2/ft2 * 48560 ft2/acre * 6” = g/cm3 * 758

Carbon Sequestration. The pyrolysis of organic matter waste to produce biochar, results in the formation of recalcitrant organic carbon which is resistant to microbial decomposition and can persist for hundreds to thousands of years. When biochar is used as a soil amendment, this organic matter waste is effectively sequestered into the soil as carbon (▇▇▇▇▇▇▇ et al, 2006). Direct measurements of the recalcitrant portions of these organic carbon inputs were not possible in this field trial as the local soil control lab did not have these capabilities. But studies of biochar composition based on different types of feedstock and production methods suggest that the recalcitrant carbon content for the biochar used in the field trial was high since it was made from wood chips charred at a temperature 575-600°C (▇▇▇▇▇ et al, 2010; ▇▇▇▇▇ et al, 2009). The amount of total organic carbon added to the soil through the treatments was estimated at 6.0, 2.3 and 8.3 tons/acre for biochar-only, compost-only and mix treatments (respectively). To further assess the effects of biochar and the other soil amendments on carbon sequestration, the amount of total organic carbon in the soil (SOC) was calculated. The results did not show a consistent, significant increase in SOC over time from the treatments when compared with the control. However, the SOC levels suggested an effect in sub-surface soils (i.e. below the 6” depth) from the biochar treatment, and this trend would likely have continued with continued monitoring. In addition to the carbon sequestered in biochar itself and increased levels in the soil, biochar has been shown to have other climate benefits. As discussed previously, biochar can act as a slow-release fertilizer, which can reduce the need for chemical fertilizers and reduce greenhouse gas emissions caused by manufacturing of fertilizers. The effects of biochar on beneficial microbial activity in the soil can also result in additional carbon storage in soils. Some studies have also reported reductions in emissions of certain greenhouse gases (N2O and CO2) from agricultural fields treated with biochar (▇▇▇▇▇▇ and ▇▇▇▇▇▇▇▇▇, 2013). In this field trial, the conversion of forestry waste into biochar likely avoided CO2 and CH4 emissions that would otherwise have been generated by the natural decomposition or burning of the waste. However, further discussion of climate benefits such as these was beyond the scope of this project, but should be considered for future studies focused specif...

Carbon Sequestration. The uptake and storage of carbon. Trees and plants, for example, absorb carbon dioxide, release the oxygen and store the carbon. Fossil fuels were at one time biomass and continue to store the carbon until burned.

Carbon Sequestration. The term ‘‘carbon sequestration’’ means the capture of carbon dioxide through terrestrial, geological, biological, or other means, which prevents the release of carbon dioxide into the atmosphere.
