IMPT for on-chain ESG analysts

How an on-chain ESG analyst integrates IMPT retirements into a Scope 3 dashboard or DeFi-style sustainability report.

Direct answer

IMPT retirements are queryable as a single Ethereum-mainnet event stream, indexable by bookingRef and beneficiary. Suitable for inclusion in The Graph subgraphs, Dune dashboards, or custom analytics pipelines.

Indexing

The CarbonCreditNFT Retired event is the canonical retirement event. Index it on a subgraph or Dune to power dashboards. Per-beneficiary aggregation gives a clean lifetime-retirement counter; per-booking aggregation gives a transaction-level audit trail.

Aggregating across registries

Each tokenId corresponds to a credit batch from a specific registry. Maintain a tokenId → registry mapping (available from IMPT) to enrich the event stream with registry detail.

Cross-platform comparison

IMPT retirements are comparable across Klima, Toucan, KlimaInfinity and other on-chain offset platforms by event-log normalisation. The key differentiator is the bookingRef — IMPT retirements are tied to specific consumer transactions, which most other on-chain platforms don't expose.
