Carbon Sequestration: Carbon Sequestration Carbon sequestration can be defined as the capture and secure storage of carbon that would otherwise be emitted to or remain in the atmosphere.
What are Carbon Credits?
Carbon credits encompass two ideas:
(1) Prevention/reduction of carbon emissions produced by human activities from reaching the atmosphere by capturing and diverting them to secure storage.
(2) Removal of carbon from the atmosphere by various means and securely storing it.
Greenhouse Gases: Greenhouse Gases Carbon Dioxide (CO2)
Methane (CH4)
Nitrous Oxide (N2O)
Sulfur Hexafluoride (SF6)
Perfluorocarbons (PFCs)
Hydrofluorocarbons (HFCs)
6.9 billion metric tons CO2e total
545 million metric tons from CH4
~40 million metric tons from manure management alone
Greenhouse Effect: Greenhouse Effect The “greenhouse effect” refers to the temperature regulation effect that certain atmospheric gases have on the earth.
The temperature-regulating gases, called “greenhouse gases” or GHGs, form a blanket around the earth that traps some heat from the sun within the earth’s atmosphere, keeping the planet warm and habitable.
Carbon Storage: Carbon Storage Carbon is continuously cycled between land and sea, in inorganic and organic form.
Most of the carbon stored in organic matter is nonliving, occurring either in soil humus or dissolved organic carbon (DOC) in seawater.
The atmosphere, in addition to comprising a major carbon reservoir, plays a critical role as a medium for rapid global exchange of CO2 and other bioactive elements.

Soil Carbon Sequestration: Soil Carbon Sequestration Carbon sequestration rates, with a change from conventional tillage to no-till, can be expected to peak in 5-10 yr with SOC reaching a new equilibrium in 15-20 yr.
Following initiation of an enhancement in rotation complexity, SOC may reach a new equilibrium in approximately 40-60 yr.
The Chicago Climate Exchange: The Chicago Climate Exchange
The Chicago Climate Exchange®: The Chicago Climate Exchange® The Chicago Climate Exchange® (CCX®) is a greenhouse gas (GHG) emission reduction and trading pilot program for emission sources and offset projects in the United States and for offset projects undertaken in Brazil and other countries. CCX® is a self-regulatory, rules-based exchange designed and governed by CCX® Members.
These members made a voluntary, legally binding commitment to reduce their emissions of greenhouse gases by four percent below the average of their 1998-2001 baseline by 2006 and a six percent reduction by 2010.

Definition of Conservation Tillage: Definition of Conservation Tillage For CCX purposes these practices are as defined in the Natural Resources Conservation Service National Handbook of Conservation Practices.
No-till/Strip-till - Managing the amount, orientation, and distribution of crop and other plant residue on the surface year-round while growing crops in narrow slots or tilled or residue-free strips in soil previously untilled by full width inversion implements;
Tillage Equipment: Tillage Equipment Full width inversion
Moldboard plow
Chisel plow
Field cultivator
Tandem disk
Offset disk
Row crop cultivator Okay to use
No-till/strip-till planter
No-till drill
Rolling harrow
Tools with wide knives
Subsoiler/ripper
Anhydrous applicator
Manure knife applicator General Guideline: After the implement has been through the field, there must still be a substantial amount of surface residue present and the soil disturbance must not be full width. If use of the implement would require that a leveling or smoothing activity follow, it would probably result in too much soil disturbance.
No credits earned during year if residue is removed or burned

Credit Calculation: Credit Calculation Baseline Calculation -- The lower of:
(a) Actual monitored amount of methane captured and destroyed by the project activity (using existing CCX monitoring protocols but with full GWP for methane). The default methane combustion efficiency for flared biogas from anaerobic digesters is 90%. Higher efficiencies may be used if supported by manufacturer’s specifications or other acceptable data. The default methane combustion efficiency for biogas utilized by electricity gensets is 100%.
(b) The methane emission calculated ex ante based on the amount of the animal manure that would decay anaerobically in the absence of the project activity, using the most recent country-specific IPCC tier 2 approach (for a description of the proposed calculation methods for projects in the U.S., see Appendix B).
Ex Ante Calculation of Baseline Methane: Ex Ante Calculation of Baseline Methane Appendix B: Ex Ante Calculations of Baseline Methane Emissions for U.S. Manure Digester Projects
1. Characterize the average livestock populations included in the anaerobic digester project for the reporting period;
2. Characterize the baseline manure management system for the project;
3. For each livestock population category and baseline manure management system, multiply the number of animals by the appropriate emission factor for that state (from Tables B.2 and B.3), by the appropriate solids separation correction factor, by the proportion of manure from those animals used in the digester, by the number of days in the period (Equation 1);
4. Sum the estimates for all population categories and baseline manure management systems (Equation 1);
5. Multiply the total estimate of methane emission by the appropriate methane GWP for the reporting period (Equation 2).
