R-Leaf® directly destroys atmospheric nitrous oxide (N₂O) after emission. Crop Intellect's Monitoring, Reporting and Verification pathway connects that physical intervention to field evidence, transparent quantification and independent assessment.

From field to verified impact
The reaction is only the beginning.
A credible climate outcome requires a documented evidence chain. R-Leaf projects are designed to show what was applied, what would have happened without the intervention, what was measured and how the result was calculated.
Baseline
A comparable untreated control or justified alternative represents the counterfactual.
Measure
Atmospheric N₂O is sampled around treated and baseline canopies.
Context
Weather, canopy and relevant field-management data are recorded.
QA/QC
Raw data pass defined quality, stability and traceability checks.
Quantify
Project and baseline behaviour are compared under the applicable methodology.
Report
Evidence and calculations are assembled in the Monitoring Report.
Verify
An independent Validation and Verification Body assesses eligible project outcomes.
Recognise
Eligible verified outcomes can support registry issuance or value-chain accounting.
Field measurement
Measure where R-Leaf actually works.
The project effect is assessed in the atmosphere around the crop canopy rather than inferred only from fertiliser use.
Two heights
Project protocols can sample at crop-canopy height and an upper reference height to characterise vertical N₂O behaviour.
Treated + control
Paired measurements are taken over matched periods so the intervention is compared with baseline behaviour under similar conditions.
Trace-gas analysis
Field and laboratory programmes can use laser-based N₂O analysers, gas spectroscopy or chromatography according to the approved protocol.
Meteorology
Wind and other relevant weather data are recorded because atmospheric transport is part of the quantification framework.
Technical note
Specific monitoring equipment, sampling frequency and field design can vary by project. The applicable methodology, PDD and monitoring plan control the formal requirements for each verified project.
Data integrity
Traceable from raw measurement to reported result.
R-Leaf monitoring retains a documented chain through sampling, processing, quality control, calculation and reporting.
Raw analyser output→Sampling records→Weather data→Stability & QA/QC→Flux calculation→Uncertainty→Monitoring Report→VVB review
Quality controls can include
- paired sampling and matched timing;
- duplicates and blanks where required;
- instrument checks and calibration records;
- stability-window assessment;
- defined outlier treatment;
- traceable processed datasets; and
- uncertainty treatment.
Why this matters
Atmospheric N₂O varies naturally. A single treated measurement is not enough. The purpose of the MRV system is to isolate a defensible project effect while retaining the evidence needed for independent review.
International Carbon Registry
M-ICR011 — a formal methodology for atmospheric N₂O destruction.
Crop Intellect developed M-ICR011, Atmospheric nitrous oxide (N₂O) destruction using Photocatalysts, for agricultural project activities that destroy ambient N₂O under natural light conditions.
MethodologyM-ICR011
SectorAgriculture
Current stageApproved
First approval10 July 2025
What the methodology covers
Measurement, baseline, quantification and verification.
The public ICR methodology describes air sampling and trace-gas analysis, calculation of N₂O flux using atmospheric concentration and meteorological information, comparison against a baseline without the photocatalytic intervention, permanence through irreversible destruction to N₂ and O₂, and additionality requirements.

The public registry currently lists the project as Under development. Verified and issued credit status should only be shown as available for purchase when the registry record confirms issuance and inventory has been published.
Value-chain / Scope 3 pathway
Independent validation for agricultural value-chain use.
In 2025, SustainCERT validated Crop Intellect's methodology Removal of atmospheric nitrous oxide (N₂O) using Photocatalytic Technology under ISO 14064-2:2019.
Scope 3 / value-chain intervention
The pathway creates a structured basis for companies seeking independently reviewed atmospheric N₂O removals within agricultural value chains.

Whether climate value is allocated within a supply chain or converted into registry credits, the website distinguishes deployment, measurement, independent verification and formal issuance rather than treating those stages as interchangeable.
