*Abstract*

The integration of blockchain technology into carbon markets offers a unique opportunity to create more transparent, inclusive, and efficient trading mechanisms. This presentation introduces a novel Blockchain Emission Trading System (BETS) model designed to align with Brazil’s new carbon market legislation (Law 15042/2024), ensuring that both large landholders and small rural producers can participate fairly. Our approach leverages official land registries, such as SICAR, to create spatially and temporally verifiable carbon credits, preventing fraud and double counting while enabling greater accessibility for smaller stakeholders who often struggle to enter regulated markets. By decentralizing the issuance and trading of carbon credits, our model aims to reduce intermediaries, lower costs, and promote broader participation, ultimately fostering a more equitable environmental and economic transition. Through a systematic mapping study, we identify key challenges and research directions for blockchain-based carbon markets and propose a framework that ensures compliance with national and international standards while prioritizing social and economic inclusivity.
