Two Years of Progress

In its first year, B4 stood out by bringing traceability and visibility to a market previously marked by a lack of public information and low reliability.

Two years later, this progress is reflected in:

• Diverse project types: forest conservation, ecosystem restoration, regenerative agriculture, renewable energy, and nature-based solutions.
• Integration with SBCE – the Brazilian Emissions Trading System, ensuring regulatory alignment and reinforcing listing credibility.
• Broad geographic coverage, with projects across different Brazilian biomes and growing international interest in B4’s model.
• Real-time traceability technology, allowing anyone to consult the full history of listed assets.

Technology and Trust as Foundations

B4’s distinctive feature is its use of blockchain technology to record and publicly share the full history of each asset. This creates an immutable and accessible system, strengthening trust among investors, companies, and society, while preventing duplication and ensuring data integrity.

Looking Ahead

For the coming years, B4 plans to:

• Expand internationally with the Brazilian climate action exchange model.
• Launch new digital solutions to broaden market access and participation.
• Consolidate an integrated ecosystem connecting originators, buyers, and strategic partners around a low-carbon economy.
