🔢Quantification tracker

What we needed to support

The core of the carbon removal methodology is a formula that is used to calculate the net CO2e moved from the fast cycle to the slow cycle by each of our interventions. This formula is decribed in detail in our Methodology v1.6.0. And to minimize errors and maximize auditability we built it into code.

What we built

The Quantification tracker captures data related to a deployment. We built it to facilitate user inputs for key variables, an easy way to collect evidence, provide traceability, and capture comments about every deployment datapoint and detail.

To improve the auditability of the system, we included capabilities like associating individual variables to the responsible party (attribution) and change management.

The Quantification tracker also implements a formula validation features to ensure accuracy.

What we would’ve wanted to build next,

Over time, we expected to update our methodology and write new ones for ocean alkalinity enhancement and macroalgae growth and sinking. This would have required formulae updates and more flexible visualization tools. Increased research, trial, pilot, and commercial deployments across geographies would have requred greater data collection automation, and publishing of quantification results for interventions for carbon accounting purposes. All these improvements were originally planned for 2024.

How it’s all connected

The quantification tracker associates data used in the calculation of CDR with each deployment. It also ties deployment inputs to outputs, associating material inputs (e.g. batch numbers and shipments) with carbon removal deployments and activity.
