Project

A Project defines a set of activities that, as a whole, produces net climate benefits relative to a baseline scenario. All data inputs, accounting, reports and credit inventory live within a project. You can create a project and configure its models and data inputs.

​
Event

Events are operational activities within a project’s boundaries. Each event holds one or more datapoints and represents something that happened at a point in time (e.g., a delivery, a meter reading, a production run). Events are one of the main types of data inputs. They occur with high frequency and their measurements often change from batch to batch. They can be associated with locations, feedstocks, evidence, and other attributes.

​
Datapoint

A datapoint is a single measured value used in production accounting. Events contain datapoints (e.g., mass, flow rate, concentration). Models consume datapoints as inputs and can output new datapoints.

​
Evidence

Evidence is documentation attached to datapoints (delivery tickets, weighbridge slips, meter readings, etc.). Evidence supports the audit trail from reporting back to source data.

​
Feedstock

A feedstock is the raw material used in the production process. In Mangrove, feedstocks are associated to the incoming Events for use in accounting and reporting.

​
Batch

A batch is the main unit of production in a project. Each batch contains the calculations and MRV data supporting that batch’s gross and net carbon activity. Batches are linked to all source data inputs and underlying evidence, and are generated by running the accounting dataflow over a chosen period.

​
Score

A score is an output calculation representing the carbon intensity (CI) of a reporting period. Scores are backed by a copy of the executed model.

​
Model

A model is a set of calculations that produce production accounting. Two main types exist: production models (operational calculations) and quantification models (methodology-specific carbon accounting). Models are built in the Model Editor using a tree of nodes: inputs, intermediate calculations, and outputs. Read more about production models.

​
Value Stream

A value stream is a way for a project to originate and commercialize its environmental attributes.

​
Ledger

Ledgers (mass accounts) track material or carbon flows across stages of a project. Mass balance accounting uses ledgers to record accumulation and use of material at each stage (e.g., feedstock received, biochar produced, carbon delivered). Not every project needs multiple ledgers. A single ledger is often enough for simpler flows.

​
System Ledger

A system ledger is a ledger auto-created by the platform to track non-physical quantities like embodied emissions or renewable instruments. Unlike user-created mass accounts, system ledgers are managed automatically and have specialized behavior for amortization and inventory tracking.

​
Embodied Emission

An embodied emission is the carbon cost of facilities, equipment, and construction, tracked in a system ledger and amortized across batches over time or production. Embodied emissions ensure that one-time capital carbon costs are fairly distributed across a project’s output.

​
Instrument

An instrument is a renewable energy certificate (REC) or renewable fuel certificate tracked in a system ledger. Instruments represent an inventory of environmental attributes that gets consumed as it is allocated to production batches, with balance tracking to prevent double-counting.
