MRV approach

About MRV

MRV = Monitoring, Reporting, and Verification

Carbon removal claims are only as credible as the data behind them. MRV refers to all the systems and processes used to build this credibility, ensuring data quality and integrity at every stage. Too often an afterthought in biochar projects, MRV should instead be a core design principle in project design and implementation — and that's how we treat it at NetZero.

Our MRV philosophy

We believe standardised data-acquisition systems fail at representing the ground truth. That is why we co-design our hardware, software, sensors, and operational procedures as a single system, using zero off-the-shelf solutions.

Minimise manual input

Every manual entry is a point of failure. Our systems capture data directly from instruments and sensors, eliminating human transcription wherever possible and reducing the risk of error and manipulation at the source.

Minimise proxy values

Default factors and population averages dilute data quality and create room for overstatement. We measure directly at every point we can, and document clearly when estimation is unavoidable.

Maintain full lineage

Every data point is traceable back to its source — instrument, timestamp, location, and collection method. Full lineage makes audits straightforward and findings defensible.

Maximise granularity

Coarse data hides variability and invites gaming. We collect at the highest resolution the system allows — across time, space, and process parameters — so that aggregated results reflect what actually happened on the ground.

What we implement for all our projects

Proprietary sensors

Designed and built in-house for each project — calibrated to the specific physical parameters and environmental conditions on the ground.

Proprietary process control and automation software

Logs every data stream automatically at the source, with no manual export or transcription step between instrument and record.

Proprietary data processing system

Raw measurements flow directly into our processing pipeline — cleaned, validated, and aggregated following project-specific protocols. Every step is traceable and auditable.

Full upstream and downstream traceability

MRV coverage extends beyond the production site. We track inputs and outputs along the full project chain — from raw materials and energy sources to final carbon removal outcomes — ensuring the net impact we report reflects what actually moves through the system.

Systematic linking of data and supporting evidence

Every data point is paired with its supporting evidence — calibration records, field logs, photos, and metadata — making MRV claims defensible under independent verification.

Designed to meet the latest and most stringent certification standards

CDR certification standards evolve quickly, raising each time the bar for quality and integrity. We already exceed all current certification expectations, and we keep anticipating evolutions to maintain full compliance and deliver the most premium biochar-based CDR credits.

Our MRV system is fully compliant with the latest certification standards: the Puro 2025 v2 methodology and the Isometric v1.3 protocol, including related modules.
