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