The global carbon market, essential for achieving Paris Agreement climate targets, faces critical fragmentation characterized by incompatible registries, heterogeneous verification standards, and opaque trading mechanisms that undermine market integrity and limit liquidity. While blockchain technology has emerged as a promising solution to enhance transparency and traceability in carbon credit trading, existing implementations operate as isolated systems that perpetuate rather than resolve market fragmentation. This study proposes and validates a comprehensive framework integrating cross-chain interoperability protocols with smart contract governance mechanisms to standardize global carbon market operations. The methodology combines design-based research with quantitative performance simulation across Ethereum, Hyperledger Fabric, and Polkadot blockchain environments, evaluating atomic swap success rates, transaction throughput, and regulatory compliance verification. Key findings demonstrate that the proposed framework achieves 94.2% atomic swap success rate through dynamic verification mechanisms, maintains 1,247 transactions per second with sub-200ms compliance validation latency, and reduces cross-jurisdictional transaction costs by 38.7%. The framework's RegulatoryCheck smart contract architecture successfully implements Article 6 Paris Agreement compliance through jurisdictional rule encoding and authority approval registries. This research contributes a replicable, technically validated framework for blockchain-based carbon market standardization, offering actionable guidance for policymakers, registry operators, and financial institutions seeking to develop globally interoperable carbon infrastructure. The findings underscore the viability of decentralized governance architectures to resolve the coordination failures currently constraining carbon market effectiveness.
