International Renewable Energy Certificate

Overview

The I-REC for electricity is an Energy Attribute Certificate issued under the International Attribute Tracking Standard maintained by the I-TRACK Foundation, with the electricity product code operated by Evident. The certificate records the attributes of electricity generation, including the energy source, so the origin of renewable electricity can be tracked and claimed. One I-REC represents one megawatt-hour of electricity produced and delivered. It is an attribute certificate for electricity and does not by itself represent a greenhouse gas emission reduction credit.

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. 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.
