Blockchain in the Carbon Market: What the SBCE Means for Companies in 2027 | Avalon Insights

Key Takeaways

The SBCE obligates large industrial sectors to monitor and report their annual carbon emissions, with Phase 1 beginning in 2027.
The MRV (Measurement, Reporting, and Verification) structure demands a high-fidelity auditable data infrastructure to avoid compliance risks.
Blockchain technology resolves five severe structural problems of legacy centralized ledger systems.
The metal, oil, gas, and cement sectors are in the first wave of the regulatory timeline, making 2026 the year of technological preparation.
The synergy between the SBCE and distributed ledgers creates data efficiency opportunities and positions Brazilian exporters advantageously for international frontier taxes like the European CBAM.

Regulatory Framework: What the SBCE Created

The Brazilian Emissions Trading System, formalized under Law 15.042/2024, moves toward its implementation phase following the public consultation in July 2026. The regulation transforms green sustainability obligations into corporate balance sheet metrics.

<0.1% of Companies

Fewer than 0.1% of Brazilian companies are directly affected by this strict regulatory obligation, concentrated in heavy industrial sectors.

📊

25k tCO2e: Threshold

Greenhouse gas emissions limit for full compliance obligations, including quota allocations and purchasing rules.

Sectoral Implementation Timeline

The timeline set by the Executive Carbon Market Secretariat (SEMC) distributed industrial and logistical sectors proportionally, allowing distinct adaptation periods:

Phase 1 (2027) Iron and Steel, Oil and Gas, Refining, Paper and Pulp, Cement, Primary Aluminum, Aviation.

How Blockchain Supports the SBCE

Distributed ledger technology establishes the technical integrity required for emission trading to operate with complete corporate safety:

01. On-chain MRV and Immutable Data

Each measurement from IoT sensors or industrial systems is recorded directly with an associated cryptographic hash, preventing operational tampering.

Ethereum / Polygon / Hyperledger

02. Quota Tokenization as RWA

Representing regulated quotas as digital tradable assets (Real World Assets) simplifies the secondary market through fractionalization and real-time transfers.

ERC-1155 / RWA Protocol
