Biochar Utilization in Soil & Non-Soil Applications

Durable carbon storage by producing biochar and applying it to soils and materials.

Registry: VCS
Sector: Biochar
Credit: VCU-BCR · tCO₂e
Issued as: org.hypercerts.claim.activity

The issued hypercert is a batch of VCU-BCR credits recorded at once, comparable to a registry issuance batch. It carries weighted contributors, a work scope and a rights record, so any app in the ATProto Collective Funding Ecosystem can read it natively.

Overview

VM0044 quantifies carbon dioxide removals from converting waste biomass into biochar at new biochar production facilities. Eligible uses of the biochar include soil applications such as croplands and grasslands, and non-soil applications such as biochar-amended concrete and other building materials. The methodology is applicable globally and credits the durable carbon stored in biochar. Each credit, issued as a Verified Carbon Unit, represents one tonne of carbon dioxide equivalent removed.

01 · Roles

Standard Registry

role · registry

Owns the policy, approves participants, anchors each issuance to its evidence.

Project Proponent

role · proponent

Registers the project and submits monitoring reports.

Validation & Verification Body

role · vvb

Independently validates the design and verifies monitored data.

02 · Policy graph

10 nodes

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.

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.
