Component blueprints are reusable templates of equations and inputs that calculate a transfer of CO₂e into or out of the atmosphere. They represent small discrete parts of carbon accounting that can be combined like building blocks to create custom and rigorous accounting for Removals, GHG Statements and entire Projects. This page provides an overview of all component blueprints.
Component Types Component blueprints are labelled with a type. The type represents a carbon accounting category and flux direction, either CO₂e sequestered or emitted.
Component Type Description CO₂e Flux Direction activityFuel and energy usage, manufacturing processes and embodied emissions Emitted ↑counterfactualBaseline calculations to compare actual sequestration against alternative scenarios Emitted ↑lossCO₂e losses and leakage before reaching permanent storage Emitted ↑reductionActivity emissions that have been reduced by other claims or offsets Sequestered ↓sequestrationCalculations of CO₂e sequestered through storage or natural processes Sequestered ↓
Each component blueprint lists its inputs; the numbers you need to provide for its calculations.
Inputs are each a particular physical quantity being measured. For example: mass, volume, concentration or density.
A particular input works with many different units as long as they are compatible with its type. Ideally data should be reported in exactly in the same value and units as shown in corroborating sources. Component blueprint equations handle transforming these provided inputs into standard SI units.
Some inputs require lists of values, for example a set of soil samples. Each individual value in a list input must be compatible with the input’s type.
The result of a component blueprint’s equations is always a mass amount of CO₂e, that is typically either kgCO₂e or tCO₂e.

Dissolved carbon sequestration key: dissolved_carbon_storage_solid_phase_steady_state
Mass of CO₂ converted to bicarbonate ions in the wastewater stream, determined using direct measurements within the treatment plant and subtracting any potential losses upon effluent discharge. The calculation uses quantification of dissolved feedstock in the solid phase (Option 1 in the WAE protocol), and assumes a steady state of feedstock mass in the control volume.
