Automating sensitivity analysis with Certify

Carbon removal suppliers can now automate sensitivity analysis with Isometric Certify—minimizing uncertainty and enhancing accuracy in net carbon removal calculations.

Uncertainty in carbon accounting arises when variables cannot be measured with complete precision or when assumptions must be made. To ensure every credit represents a tonne of carbon dioxide removed from the atmosphere, this uncertainty must be fully accounted for and addressed. That’s why the Isometric Standard requires all projects to conduct a sensitivity analysis, starting at their first verification.

A sensitivity analysis identifies the variables with the greatest impact on a project’s net carbon removal, ensuring they are addressed conservatively.

Until now, suppliers had to use time-consuming, error-prone spreadsheets to conduct their sensitivity analysis. This meant individually accounting for hundreds of datapoints, performing repetitive calculations, and sometimes repeating the entire process if their carbon accounting changed or if issues were identified during verification.

With Certify, running a sensitivity analysis now takes seconds—reducing manual effort, simplifying results, and making it easy for verifiers to review. Watch the video below to learn how.

Certify does the heavy lifting, allowing suppliers to focus on how they account for uncertainty rather than on the calculations themselves. This can be done by:

• Providing a standard deviation, which Certify uses in variance propagation to conservatively quantify net carbon removal
• Justifying that a datapoint is conservative, for example, if an uncertainty factor has already been applied)
• Providing evidence that a datapoint is accurate primary data and does not require an uncertainty discount

Certify then compiles all results and justifications into a clear, transparent format—making it simple for verifiers to review and accelerating the verification process.

By streamlining sensitivity analysis, Certify makes it faster than ever to prepare high-quality carbon accounting. Learn more or get started today.
