The intervention module is used for quantify greenhouse gas emissions and removals using DNDC, which can be used for reporting to and verification by carbon standards.
The Measure API Quantify greenhouse gas emissions and removals using DNDC, which can be used for reporting to and verification by carbon standards.
Inputs
The Measure API requires detailed management data inputs for both
- Baseline scenarios and intervention events.
- Data for the entirety of the program you are measuring is required.
- Crop parameters, soil and weather data are automatically included in the API.
Quantification
Outcomes = Counterfactual period - Intervention period
The field history is used to initiate the DNDC model with field level management practices as well as to construct the counterfactual.
The Intervention period corresponds to time after the regenerative practice change has happened.
The outcomes reflect the difference between what would have happened (counter factual) and what happened (intervention).
Uncertainty in our quantification
Quantifying model uncertainty is critical for transparent use in ecosystem markets, supply shed and ESG reporting.
Model structural uncertainty is defined as model accuracy when all inputs are known and free of error. Quantifying uncertainty requires the use of independent validation data. The basic approach includes statistical analysis of the residuals of modeled versus measured estimates of greenhouse gas emission.
We discount model estimates of GHG reductions to account for this uncertainty. We calculate an appropriate deduction based on an acceptable confidence interval. This interval is flexible for both Scope 1 & 3 assets. The structural uncertainty deduction applies to the aggregate at project scale, since the deduction factor depends on the number of fields and simulations included.
