Accounting for Nature (CreditNature / NaturePlus)

Overview

Accounting for Nature is a framework and standard for measuring and reporting the environmental condition of assets such as native vegetation, fauna, soil, and water. Each Environmental Account is built using an accredited method that specifies indicators and reference benchmarks and combines them into an Environmental Condition Index, or Econd, a single value from 0 to 100 that describes how close an asset is to its undisturbed reference state. Measured condition and its change over time underpin nature units and products issued by users of the framework, including CreditNature.

01 · Roles

The workflow as an explicit directed graph. In Graph each column is one role, so you can see who acts at each step; every node names the org.broadlistening.policy.block.* def it resolves to plus its input and output record. Data flow switches to a lineage view that makes explicit what data each node needs and makes, with dependency arcs tracing every record back to the node that produced it, including where the Darwin Core occurrence + measurement records feed in. Hover to trace, click to inspect; revise edges (dashed) send work back.

03 · Generated lexicon records

The records this methodology compiles to, ready to write to a PDS. The first tabs are the new policy engine records; the ★ claim.activity tab and those after it are reused ATProto Collective Funding Ecosystem records (org.hypercerts.*): the issued hypercert batch, its rights, an example verification attachment and a retirement receipt. The ◈ dwc.occurrence and ◈ dwc.measurement tabs are the Darwin Core field evidence the monitoring node writes; see the section below.
