1. Project Summary

The DaedArch Corporation has developed a sensor-based MRV platform specifically designed for the carbon markets. This platform captures ground-truth environmental data through Internet of Things (IoT) sensors deployed in carbon removal projects, including biochar, Bioenergy with Carbon Capture and Storage (BECCS), enhanced weathering, and direct air capture. This report demonstrates how the data collected and processed by DaedArch meets the reporting requirements set forth by Puro.earth for carbon removal credits.

2. Methodology

2.1 Data Collection

Data collection is performed through a network of IoT sensors strategically placed at project sites. These sensors measure various environmental parameters relevant to carbon removal, including but not limited to:

• CO₂ concentration (ppm)
• Soil carbon content (g/kg)
• Moisture levels (%)
• Temperature (°C)
• Biomass growth metrics (kg/m²)

The following data collection protocols shall be adhered to:

• Sensors shall be calibrated bi-annually according to ISO 17025 standards.
• Data shall be collected at a minimum frequency of once per hour.
• Data integrity shall be ensured through encryption during transmission.

2.2 Data Processing

The raw data collected by the sensors is processed using certified algorithms that comply with ISO 14064-2 standards for greenhouse gas accounting. The processing steps include:

1. Data Validation: All incoming data shall be validated against predefined thresholds.
2. Data Aggregation: Data shall be aggregated to daily and monthly summaries for reporting.
3. Data Correction: Any outliers detected during validation shall be investigated and corrected based on historical data trends.

2.3 Data Reporting

The processed data is formatted into a reporting template that aligns with Puro.earth’s requirements. The report shall include:

• Project ID
• Reporting period
• Summary of collected parameters
• Verification-ready data tables

3. Measurement Data

3.1 Data Fields

The following data fields shall be included in the reporting template:

| Field Name | Data Type | Description | |------------------------|------------------|----------------------------------------------------------| | Project ID | String | Unique identifier for the carbon removal project. | | Reporting Period | Date Range | Start and end date of the reporting period. | | CO₂ Concentration | Float (ppm) | Average CO₂ concentration measured during the period. | | Soil Carbon Content | Float (g/kg) | Average soil carbon content measured during the period. | | Moisture Levels | Float (%) | Average soil moisture levels during the period. | | Temperature | Float (°C) | Average temperature recorded during the period. | | Biomass Growth | Float (kg/m²) | Average biomass growth metrics recorded during the period.|

3.2 Data Formats

Data shall be formatted in accordance with the following specifications:

• JSON Format: The report shall be generated in JSON format for easy integration with Puro.earth’s systems.

Example JSON structure:

`json { "project_id": "Puro-12345", "reporting_period": { "start_date": "2023-01-01", "end_date": "2023-01-31" }, "measurement_data": { "co2_concentration": 400.5, "soil_carbon_content": 15.2, "moisture_levels": 20.5, "temperature": 22.3, "biomass_growth": 3.5 } } `

3.3 API Endpoints

DaedArch provides the following API endpoints for data submission and retrieval:

• POST /api/v1/reports: Submit a new verification report.
• Request Body: JSON formatted report as described above.
• Response: 201 Created, with report ID.

• GET /api/v1/reports/{report_id}: Retrieve an existing report by ID.
• Response: JSON formatted report data.

4. Verification Findings

4.1 Audit Trail

An audit trail shall be maintained to ensure the integrity and traceability of data. The following elements shall be included in the audit trail:

• Timestamp of data collection
• Sensor ID and location
• Data validation logs
• Data processing logs
• User actions (e.g., data corrections)

All logs shall be stored in a secure database with restricted access, ensuring compliance with GDPR and other relevant data protection regulations.

4.2 Conformity Assessment Procedures

The following conformity assessment procedures shall be implemented to ensure compliance with Puro.earth standards:

1. Internal Audits: Conduct quarterly internal audits of the MRV system to ensure adherence to operational protocols.
2. Third-Party Verification: Engage an accredited third-party verifier annually to assess the accuracy and reliability of the reported data.
3. Continuous Monitoring: Implement a continuous monitoring system for real-time data validation and anomaly detection.

5. Conclusion

This sample verification report demonstrates how DaedArch Corporation's sensor-based MRV platform meets the rigorous standards set forth by Puro.earth for carbon removal credits. The methodologies employed for data collection, processing, and reporting ensure compliance with industry standards and provide a robust framework for verification. By adhering to the outlined requirements and maintaining a comprehensive audit trail, DaedArch is committed to transparency and integrity in the carbon markets.

The successful integration of this MRV platform into Puro.earth’s carbon registry will facilitate the effective tracking of carbon removal credits, thereby supporting the global transition towards a sustainable and carbon-neutral future.
