How do I report my Carbon Flux Values?
Voluntary Reporting of Greenhouse Gases Program is Suspended as of May 2011. The U.S. Energy Information Administration (EIA) Voluntary Reporting of Greenhouse Gases (“1605(b)”) Program has been suspended due to recent reductions in budget appropriations and is effective immediately.
You may still submit data to the 1605(b) Program using the program’s Workbook Form via EIA’s Secure File Transfer mechanism. However, EIA will not be able to process and review submitted data or offer respondent support on the submitted data. Should a respondant submit data under the current collection cycle to EIA, the data will be retained in their electronic records. If the 1605(b) Program resumes normal operations, your submitted data will be reviewed and processed at that time. You will be notified in the future if the 1605(b) Program resumes normal operation.
If you have any questions, please contact the survey manager, Paul McArdle, at firstname.lastname@example.org
Form EIA-1605 provides the means for the voluntary reporting of greenhouse gas emissions, reductions, and sequestration under Section 1605(b) of the Energy Policy Act (EPAct) of 1992. The form implements the guidelines for filing voluntary reports issued on April 21, 2006 by the Department of Energy’s (DOE) Office of Policy and International Affairs (71 FR 20784), Guidelines for Voluntary Greenhouse Gas Reporting (10 CFR Part 300).
The purpose of the Voluntary Reporting Program is to encourage corporations, government agencies, non-profit organizations, households, and other private and public entities to submit annual reports of their greenhouse gas emissions, emission reductions, and sequestration activities. Form EIA-1605 provides the means for voluntary reporting that is complete, reliable, and consistent.
The 1605b electronic reporting guidelines for this reporting period are still being developed by DOE and should be finalized by August of 2007. On November 9, 2006, DOE’s Energy Information Administration (EIA) submitted the "Voluntary Reporting of Greenhouse Gases," form EIA-1605 to the Office of Management and Budget (OMB) for review and a three-year extension under the Paperwork Reduction Act of 1995. A notice containing the General Guidelines was published in the Federal Register on November 9, 2006. Comments are due on the revised Forms and Instructions by December 11, 2006. DOE’s Energy Information Administration (EIA) has initiated the development of the forms and software necessary to implement the revised guidelines. Forms and Instructions are available on the EIA web site at: www.eia.gov/oiaf/1605/1605b_form_and_instructions.htm. EIA expects to complete the software necessary for electronic reporting by spring or summer 2007, in time to permit full implementation of the revised program during 2007.
Requests for additional information should be directed to www.eia.gov/oiaf/1605/contact.html
The COMET2 site is not able to report your carbon values to DOE until the electronic submission procedures are finalized. However, You can submit the results of your COMET2 runs to DOE using this DOE 1605b website link: www.eia.gov/oiaf/1605/index.html.
Save your COMET2 report to disk to use as a resource in filling out the DOE report. You can save and download the report by right clicking on the link provided on the web site tool page.
What does Unknown mean for an uncertainty value?
The "Unknown" uncertainty value does NOT mean the model does not support or have have cropping system and tillage data for your area. Nor does it mean that the C changes and fuel usage reported are considered unreliable. It only means there is currently insufficient statistical accuracy to estimate the uncertainty for your selected management scenarios.
The uncertainty calculation, not the COMET2 model itself, has problems with dry, low productivity, and wet, high productivity environments. Soon we plan to address some of these issues with an upgraded statistical model.
However, the basic limitation to the uncertainty is a lack of soil carbon studies coupled with the site, management and production data needed to validate the environmental extremes.

I need Help with the Management Systems in COMET2:
Currently, COMET2 contains the most common crop rotations at the Major Land Resource Area (MLRA) level, determined from the National Resource Inventory (NRI) and other national databases. However, not all possible crop rotations can be included in the model, and thus, if your particular management system is not listed, we recommend that you choose the rotation which is most similar in terms of residue production and fertilizer management. Or, select the "Other" option to calculate a base carbon level which is representative of the dominant crop sequence in your area.
Work is ongoing to include more perennial and horticultural crops as well as vegetable cropping systems.
Unfortunately, the basic limitation to adding additional management rotations is a lack of soil carbon studies coupled with the site, management and production data needed to validate the model results.
I need more information about Century:
The CENTURY model in COMET2 is a general model of plant-soil nutrient cycling which is being used to simulate carbon and nutrient dynamics for different types of ecosystems including grasslands, agricultural lands, agroforestry, rangelands, and orchards.
The CENTURY modeling enviroment is a complex super model composed of many sub-models: a soil organic matter/decomposition submodel, a water budget model, a grassland/crop submodel, a forest production submodel, and a management and events scheduling functions model. CENTURY computes the flow of carbon, nitrogen, phosphorus, and sulfur through the model's compartments. The minimum configuration of elements is C and N for all the model compartments. The organic matter structure for carbon(C), nitrogen(N), phosphorus(P) and sulfor(S) are identical; the inorganic components are computed for the specific inorganic compound.
The CENTURY Model embodies our best understanding to date of the biogeochemistry of Carbon, Nitrogen, Phosphorus, and Sulphur in the ecosystem. The primary purposes of the model are to provide a tool for ecosystem analysis, to test the consistency of data and to evaluate the effects of changes in management and climate on ecosystems.
If you are using the COMET2 site in some academic or research project and you are willing to test and evaluate COMET2 for your study. Feel free to contact Dr Keith Paustian
What is the COMET2 Tool and How does it relate to Greenhouse Gas Reporting:
The CarbOn Management Evaluation Tool (COMET2) was originally released in 2006 to coordinate with the Department of Energy's 1605(b) revised guidelines for the voluntary reporting of greenhouse gas emissions and emission reductions. It is identified as a tool to use in the document Technical Guidelines for Voluntary Reporting of Greenhouse Gas Program Section 1605(b) Part H.
COMET2 helps farmers and ranchers make management decisions as it report the effectiveness of adopting land-management changes in sequestering soil carbon. This benefits both producers and the environment. It is easy to use and very accessible. The tool provides the farmer/rancher with various senarios at fingers reach.
COMET2 is a web-based decision support calculation tool that allows users to estimate changes in soil carbon storage from agricultural management history on cultivated lands for most regions and cropping systems prevalent in the United States. COMET2 delivers and estimate of annual soil carbon fluxes along with fuel and fertilizer use which can be reported to the 1605(b) voluntary greenhouse gas reporting system. Producers insert their current and alternative farming/grazing/agroforestry/orchard practices into COMET2, which then estimates changes in fuel use, fertilizer and carbon storage from each alternative.
COMET2 has great potential for future management of farm greenhouse gas emissions, and it also provides a valuable cost benefit to producers.
I need Help with Forestry Management Practices:
This version of the COMET2 Tool features the most common AgroForestry management practices based on specific geographic regions. Please refer to the documentation that describes these practices in more detail: Agroforestry Practrices and Agroforestry Modeling
I need Help with NRCS CSP EAM-40 Requirements:
If you are an approved NRCS CSP participant for the EAM-40 Carbon Sequestration enhancement you are to provide printouts of the results page of your three management scenarios. You will need to supply additional information and attach a printout of the carbon storage report for each of the current and planned managements identified above, and return this information to your verifier, your Local NRCS District Conservationist. You can download the required document by right clicking this link.
CSP Participation Guidelines: Participants shall run the COMET2 model using their current management(s) throughout the reporting period, and also make a minimum of three runs of COMET2 using different management and conservation scenarios.
Documentation Required from Approved CSP Participants: Use of the COMET2 tool is documented by providing printouts of the results page, and filling out a form to show how soil carbon changes with changes in crop rotations and tillage intensities.
Adam Chambers, - NRCS, Portland, Adam.Chambers@por.usda.gov will be able to answer additional questions about the CSP program requirements.
I need Help with 1605(b) Laws and Regulations:
The Energy Information Administration (EIA) of U.S. Department of Energy (DOE) is the lead government agency responsible for collection of greenhouse gas reports under the revised Section 1605(b) of the 1992 Energy Policy Act. The Energy Information Administration (EIA) has initiated the development of the forms and software necessary to implement the revised guidelines. Draft forms and Instructions are available on the EIA web site at www.eia.gov/oiaf/1605/1605b_form_and_instructions.htm.

I need information on Carbon Trading:
Carbon Trading is an important policy alternative to taxation, and has the important advantage that it can work with voluntary agreements. The aim of both trading and voluntary agreements is to motivate positive responses to a shared problem. In this case, the shared problem is enhancing and protecting the environment. NRCS supports the "Market-Based Approach to Conservation" in the 2007 Farm Bill.
USDA and other federal agencies soon will be authorized to ensure that environmental goods and services produced by agriculture and forests can be used as offsets in regulatory, voluntary partnerships and incentive programs. Generating substantial private-sector demand for environmental goods and services hinges on the ability to use environmental credits generated by agricultural and forest conservation activities.
Agriculture and forestry conservation activities can produce environmental services, such as clean air and water, at lower costs than conventional pollution controls on industrial emissions and effluent. Traditional environmental regulations require firms to reduce pollution to a set level or to install specific technologies and practices. While fairly straightforward, this approach can be costly both to the firms and to society because firms with high costs of pollution reduction and those with low costs are required to meet the same requirements, which may waste resources. In addition, voluntary private-sector partnerships, and incentive programs, both public and private, are generating demand for environmental goods and services associated with agricultural and forest conservation activities. Private sector environmental markets can offer efficiency improvements over traditional regulations and could result in overall increases in environmental and conservation benefits.
In a trading system, companies (assuming they are the trading
entities), receive emissions allowances for greenhouse gases. They need to
reduce their emissions to that level, buy allowances from others to effectively
reduce their emissions, or sell to others if they have an excess of allowances.
For example, a business that is a point source of water pollution could pay
a farmer to establish buffer strips to reduce nutrient runoff. These buffer
strips might also rehabilitate wetlands, sequester carbon and provide
