Methodologies

1. INTRODUCTION

1.1 Background and Justification

The urgent need for effective carbon sequestration strategies in the fight against climate change has driven innovation in the utilization of biomass for long-term carbon storage. Regenerative agriculture (Regen Ag) is a holistic approach to farming that emphasizes the restoration and enhancement of the natural ecosystem processes.

Industrial hemp (Cannabis sativa) has emerged as a powerful tool in this endeavor due to its rapid growth, high biomass yield, and multiple ecological benefits.

Rationale and Financial Incentives from Carbon Credit Income for Industrial Hemp Farmers:

The availability of carbon credit income provides a significant financial incentive for farmers growing industrial hemp. By participating in carbon credit programs, farmers can monetize the carbon sequestration benefits of their hemp crops. This not only provides an additional revenue stream but also promotes sustainable agricultural practices. The rationale behind this is that industrial hemp, with its high biomass yield and rapid growth, is an effective crop for sequestering carbon. The income from carbon credits helps offset the costs of implementing regenerative practices and encourages more farmers to adopt sustainable methods.

Industrial Hemp:

  • Rapid Growth: Industrial hemp can reach maturity within 3-4 months, allowing for multiple harvests per year in favorable climates.
  • High Biomass Yield: Hemp produces a substantial amount of cellulose-rich biomass, making it ideal for carbon sequestration.

Regenerative Agriculture:

  • Ecosystem Restoration: Regen Ag practices focus on improving soil health, increasing biodiversity, and sequestering carbon, contributing to resilient and sustainable agricultural systems.
  • Sustainability: These practices reduce reliance on chemical inputs, enhance water retention, and improve nutrient cycling.

The integration of industrial hemp into regenerative agriculture systems leverages its biological characteristics to enhance soil health, increase carbon sequestration, and provide multiple ecological co-benefits. The adoption of advanced monitoring technologies, such as those used by CarbonSpace, further ensures accurate measurement and verification of the environmental benefits achieved.

CarbonSpace and NEE:

  • Advanced Monitoring: Utilizing flux towers and satellite data to measure Net Ecosystem Exchange (NEE) provides accurate, high-frequency data on CO2 fluxes.
  • Proprietary Algorithms: Machine learning models enhance the accuracy of carbon sequestration estimates.
  • Third-Party Verification: The CarbonSpace digital Measurement, Reporting, and Verification (dMRV) tool is third-party verified by Control Union according to ISO 14064-3, ensuring credibility and reliability.

This methodology aims to provide a systematic approach for implementing regenerative agriculture practices using industrial hemp, facilitating the issuance of Carbon Removal Units (CRUs) and contributing to global carbon reduction efforts.

1.2 Carbon Credit Issuance

Carbon credits in our methodology are derived from initiating regenerative agricultural practices, growing industrial hemp for its sequestration capacity, and spreading biochar to enhance the sequestration and durability of Soil Organic Carbon (SOC).

These practices collectively contribute to a comprehensive approach to carbon sequestration:

  • Regenerative Agricultural Practices: These practices, such as crop rotation, reduced tillage, and cover cropping, are essential for improving soil health and biodiversity. By enhancing soil organic matter and microbial activity, these methods significantly boost the soil’s ability to store carbon.
  • Industrial Hemp Cultivation: Industrial hemp is an ideal crop for carbon sequestration due to its rapid growth, high biomass yield, and robust root system. Hemp’s deep roots enhance soil structure and increase organic matter input, further contributing to SOC.
  • Biochar Application: Biochar, a stable form of carbon created from biomass, is used to improve soil structure, water retention, and nutrient availability. Its application in the soil enhances microbial activity, which is crucial for effective carbon sequestration. Biochar’s long-term stability ensures that carbon remains sequestered in the soil for extended periods.

Importantly, we issue a single, distinct carbon credit that encompasses these combined activities. This unified credit approach ensures that the combined benefits of regenerative agriculture, hemp cultivation, and biochar application are fully accounted for in a streamlined and transparent manner.

It is critical to note that this carbon credit is entirely separate from the process of manufacturing biochar. The credit specifically pertains to the sequestration activities and the enhancements made by applying biochar to the soil, not to the production of biochar itself.

By integrating these practices, our methodology not only supports substantial carbon sequestration but also promotes sustainable agricultural practices that improve soil health and ecosystem resilience. This comprehensive approach ensures the durability and effectiveness of carbon credits, contributing significantly to climate change mitigation efforts.

  • Environmental and socio-economic impacts
  • Monitoring plan and data management strategies
  • Risk assessment and management plan

The PDD serves as a comprehensive plan ensuring transparency, accountability, and effectiveness of the carbon sequestration project.

Reasons Why Measuring NEE of CO2 is Superior for Understanding Carbon Fluxes:

Measuring the Net Ecosystem Exchange (NEE) of CO2 provides a more holistic understanding of carbon fluxes compared to just sampling soil organic carbon. NEE captures the net balance of carbon absorbed by plants through photosynthesis (Gross Primary Production) and carbon released through ecosystem respiration. This comprehensive measurement accounts for both aboveground and below ground carbon dynamics, providing a more accurate and real-time assessment of an ecosystem’s carbon sequestration capacity. By using flux towers and integrating satellite data, the methodology ensures high-frequency, accurate monitoring of CO2 fluxes, enhancing the reliability and robustness of carbon sequestration estimates.

1.6 Additionality

In the context of carbon credit availability, the cultivation of industrial hemp can be considered additional for several reasons, particularly focusing on the small size of planting operations and various barriers to entry:

Small Size of Planting Operations:

  • Limited Scale: Many industrial hemp farming operations are relatively small-scale compared to other agricultural enterprises. This small scale limits their overall economic impact and market presence, making it less likely that these operations would be established without specific incentives like carbon credits.
  • Economies of Scale: Smaller operations do not benefit from the economies of scale enjoyed by larger farms, making it harder to achieve profitability without supplemental income from carbon credits.

Licensing Barriers:

  • Regulatory Hurdles: Growing industrial hemp requires navigating a complex web of licensing and regulatory requirements. These can vary signifantly by region, often involving strict controls and oversight due to the plant’s association with cannabis.
  • Time and Cost: Obtaining the necessary licenses can be time-consuming and costly, deterring potential farmers from entering the market without the financial incentive provided by carbon credits.

Lack of a Cash Market:

  • Market Development: The market for industrial hemp and its products is still developing. There is a lack of established supply chains and reliable market demand, making it difficult for farmers to predict profitability.
  • Price Volatility: Prices for hemp products can be volatile due to the nascent nature of the market, further adding to the financial risk for farmers.

Other Difficulties:

  • Technical Expertise: Growing industrial hemp requires specific knowledge and expertise, particularly in terms of managing soil health and optimizing plant growth for biomass production. This expertise is not widely available, posing an additional barrier.

4 MEASUREMENT AND VERIFICATION OF NEE

4.1 Overview of Net Ecosystem Exchange (NEE)

Net Ecosystem Exchange (NEE) is a critical metric for assessing the carbon balance of an ecosystem. NEE represents the net exchange of CO2 between an ecosystem and the atmosphere, accounting for both carbon uptake through photosynthesis and carbon release through respiration. The primary components of NEE are:

      • Gross Primary Production (GPP): The total amount of CO2 captured by plants during photosynthesis.
      • Ecosystem Respiration (Reco): The total amount of CO2 released through the respiration of plants, animals, and microorganisms.

The formula for NEE is expressed as:

NEE = Reco – GPP

A negative NEE value indicates that an ecosystem is a net carbon sink, absorbing more CO2 than it releases, while a positive NEE value indicates a net carbon source.

Importance of NEE in Regenerative Agriculture:

      • Carbon Sequestration: NEE provides a direct measure of an ecosystem’s carbon sequestration capacity.

  • Neural Networks: Deep learning models that capture complex, non-linear relationships in the data.

Implementation:

  • Training and Validation: Models are trained on a subset of data and validated on independent datasets to prevent overfitting and ensure generalizability.
  • Feature Selection: Key features (e.g., NDVI, EVI, soil moisture, temperature) are selected based on their relevance to NEE.

Advantages:

  • Enhanced Accuracy: Machine learning models improve the precision of NEE estimates by capturing complex interactions among variables.
  • Scalability: These models can process large datasets from multiple sources, providing scalable solutions for carbon monitoring.

Calculation Example: NEE Estimation

Using the data from flux towers and satellite observations, a machine learning model can estimate NEE. For instance, consider the following inputs:

  • GPP (Gross Primary Production): Measured by flux towers and validated with NDVI/EVI from satellite data.
  • Reco (Ecosystem Respiration): Derived from soil temperature and moisture data.

The model combines these inputs to estimate NEE:

NEE = Reco – GPP

If GPP is measured at 25 tCO2/ha/year and Reco is measured at 20 tCO2/ha/year:

NEE = 20 − 25 = − 5 tCO2 / ha /year

This negative NEE value indicates that the ecosystem is acting as a net carbon sink, absorbing 5 tCO2/ha/year.

By integrating flux tower measurements, satellite data, and advanced algorithms, this methodology ensures accurate and reliable estimation of NEE, supporting the quantification of carbon sequestration in regenerative agriculture systems using industrial hemp.

5. QUANTITCATION OF CARBON SEQUESTRATION

5.1 Calculation of Carbon Content in Biomass

The quantification of carbon sequestration in industrial hemp biomass is determined using Net Ecosystem Exchange (NEE) measurements, as detailed in Section 4. This approach leverages continuous data collection from flux towers and satellite data integration to accurately estimate the amount of CO2 captured by the hemp plants during the growing season.

Net Ecosystem Exchange (NEE).

Definition: NEE represents the net balance of carbon absorbed by plants through photosynthesis (Gross Primary Production, GPP) and carbon released back to the atmosphere through ecosystem respiration (Reco).

Formula:

NEE = Reco − GPP

A negative NEE value indicates net carbon uptake by the ecosystem, while a positive value indicates net carbon release.

Data Collection:

  • Flux Towers: Equipped with sensors to measure CO2 fluxes at high frequencies, capturing real-time data on carbon exchange between the ecosystem and the atmosphere.
  • Satellite Data: Provides additional spatial and temporal resolution, helping to validate and scale up the measurements obtained from flux towers.

Example Calculation:

Assume the following values are obtained from the flux tower and satellite data:

  • GPP: 30 tCO2/ha/year (carbon uptake through photosynthesis)
  • Reco: 25 tCO2/ha/year (carbon released through respiration) The

NEE is calculated as:

NEE = 25 − 30 = − 5 tCO2/ha/year

This negative value indicates that the hemp biomass has sequestered 5 tCO2/ha/year.

5.2 Monitoring, Reporting, and Verification (MRV) Protocols

Robust MRV protocols are essential to ensure the accuracy, transparency, and credibility of the carbon sequestration claims. The MRV process involves continuous monitoring, systematic reporting, and independent verification.

Monitoring:

  • Continuous Data Collection: Utilizing flux towers and satellite data to continuously measure and monitor CO2 fluxes. This provides real-time insights into the carbon dynamics of the hemp fields.
  • Data Validation: Ensuring data quality through regular calibration of sensors and validation against independent measurements.

Reporting:

  • Periodic Reports: Preparation and submission of detailed reports on carbon sequestration progress, including NEE measurements, associated emissions, and net CO2 removal calculations.
  • Transparency: Providing clear, accessible reports to stakeholders, ensuring that all data and methodologies are openly shared.

Verification:

  • Third-Party Verification: Engaging independent verification bodies to audit the MRV process and validate carbon sequestration claims. The CarbonSpace digital Measurement, Reporting, and Verification (dMRV) tool, verified by Control Union according to ISO 14064-3 standards, is used for this purpose.
  • Site Visits: Conducting regular site visits to ensure compliance with the methodology and to verify the accuracy of data collection and reporting processes.
  • Certification: Upon successful verification, issuing carbon credits (CRUs) that represent the validated carbon sequestration achieved by the project.

Example Verification Steps:

    1. Data Collection: Gather continuous NEE data from flux towers and satellite observations.
    2. Data Analysis: Analyze the data using proprietary algorithms to estimate carbon sequestration.
    3. Reporting: Prepare detailed reports summarizing the findings and methodologies used.
    4. Third-Party Audit: Independent auditors review the reports and conduct site visits.
    5. Certification: Issue carbon credits based on the verified net CO2 removal.

By following these MRV protocols, regenerative agriculture projects using industrial hemp can ensure that their carbon sequestration efforts are accurately quantified, transparently reported, and reliably verified, thereby enhancing the credibility and marketability of the resulting carbon credits.

6. CARBON CREDIT DURABILITY
