What this page covers
This page is the orientation map for EDMA's ESG flows. The protocol supports 14 distinct ESG routes that all run through the same protocol-level architecture: evidence capture, attestation, PoV Gate validation, token mint, marketplace listing, settlement. What differs across routes is the unit of attestation, the methodology that converts physical events to protocol units, and the target market.
Every route lives on the same rail and benefits from the same uniqueness enforcement, registry-mirror integration, and audit-grade receipts. The 14 routes split structurally into two sides — Energy routes that attest kilowatt-hours and Carbon routes that attest tonnes of CO2 equivalent. The two-sided structure reflects the underlying physical distinction between adding clean energy to the grid (Energy) and removing or avoiding emissions (Carbon).
Energy routes in detail
Energy routes attest kilowatt-hours of clean energy generation or consumption. The base units are $ETT (one token per 10 kWh of verified renewable generation, non-transferable) and $CLE (one token per 1 MWh at retail tier). Specialization happens at the route level — different methodologies, different verifier networks, different downstream markets.
The seven Energy routes: Energy flow is the canonical route, the simplest path from generation to certificate sale. Compliance credits handles REC, SREC, SMART, and STC programs with regional-program integration. Granular and flex handles 24/7 carbon-free energy programs with timestamp and grid-zone metadata. Community share handles corporate offtake pools and community-scale aggregation. Energy-side carbon handles additionality-based carbon claims from clean energy displacement. Diesel to solar microgrids handles avoided-diesel emissions from microgrid conversions. Renewable thermal handles renewable thermal certificates (RTC) and GO-Heat programs.
Physical evidence is captured at the source: smart meters for energy generation and consumption, IoT sensors for emissions monitoring, lab analyses for soil carbon, satellite imagery for forest cover, customs records for trade lots. Every evidence type has a canonical schema (MeterReadingBatch.v1, EmissionsBatch.v1, etc.) and is signed at the source.
A registered attestor (utility, certified auditor, lab, satellite operator, project verifier) reviews and co-signs the evidence. The attestor is in the on-chain registry; their signature carries their reputation weight. Multiple attestors can sign jointly for higher-trust applications; some routes require minimum role diversity (e.g., AUDITOR plus METER_OP).
The protocol validates: (1) attestation quorum (minimum number of verifications with required role diversity), (2) equality of evidence (all signatures reference the same canonical evidenceHash), (3) One-Claim exclusivity (this evidenceHash has not been finalized elsewhere on the protocol). If any check fails, the gate denies and no token mints.
On PoV PASS, the appropriate token mints to the producer's wallet: $ETT for energy generation (1 per 10 kWh), $CLE for retail-tier energy (1 per 1 MWh), Carbon NFTs for verified removals or avoidance (1 per tCO2e). The mint includes full metadata: source identifier, timestamp, geographic location, methodology, attestor signatures.
The producer lists the token on the EDMA marketplace for sale. Buyers can purchase outright (for later resale or retirement), retire immediately (claiming the environmental attribute against their compliance program), or attach to a trade delivery (the token retires at trade milestone, with the certificate appearing on the shipment receipt).
The trade settles in $EDSD with the 4 percent certificate fee applied (2 percent buyer + 2 percent seller). The fee splits 50/50: half burns in $EDM permanently, half routes to the TreasurySplitter and divides across the five buckets (Attestors, Network ops, Builders, Ecosystem, Stakers). The receipt records the fee line, burn hash, and per-bucket amounts; auditors can replay the full event from L1.
Carbon routes in detail
Carbon routes attest tonnes of CO2 equivalent removed or avoided. The base unit is Carbon NFTs with full methodology metadata (Verra, Gold Standard, ICVCM Core Carbon Principles, ISO 14064) and vintage. Each Carbon NFT has a methodology classification that determines acceptable buyers and pricing tiers.
The seven Carbon routes: Carbon flow is the canonical route, the simplest path from verified emissions reduction to credit sale. Reforestation handles afforestation and reforestation (ARR) with growth-curve methodology. Avoided loss handles REDD+ (reducing emissions from deforestation) and Improved Forest Management. Blue carbon handles mangroves, saltmarsh, and seagrass with marine-ecosystem methodology. Soils and biochar handles agricultural soil carbon and biochar sequestration. Methane avoidance handles waste and agricultural methane reduction with CH4-specific methodology. Tech removals handles direct air capture (DAC), bioenergy with carbon capture (BECCS), and enhanced mineralization.
What's common across all routes
The protocol layer is identical for every route. Evidence captures at the source with cryptographic signing. Attestors review and co-sign with role diversity requirements. The PoV Gate validates quorum, equality of evidence, and One-Claim exclusivity. Tokens mint only on PASS. Marketplace listings expose buy/retire/attach options. Settlement clears in $EDSD with the standard 4 percent fee and 50 percent burn in $EDM.
Registry mirrors handle external integration uniformly. Where a route maps to an external compliance registry (PJM-GATS for SRECs in PJM markets, AIB for European GOs, Verra registry for VCS credits, Gold Standard registry for GS-VER credits, ICVCM-aligned registries for high-integrity carbon), the registry mirror binds the external serial to a single on-chain claim. The protocol's One-Claim Ledger then prevents the same evidence from being monetized through multiple registries simultaneously.
Revocation is route-agnostic. If essential verification is later revoked (attestor finds evidence was false, registry pulls the serial, regulator disqualifies the methodology), the protocol flags dependent assets through flagRevoked(claimId) and provides a rectify path when quorum is restored. The lineage is append-only; the receipt history is never erased, just amended with the revocation event. This works the same way across all 14 routes.
