The 马上碳惠 (Instant Carbon Benefit) platform integrates a methodology development system with a digital trading ecosystem for scrap steel recycling emissions reduction credits. The architecture flows from methodology validation and data collection standards through automated emissions calculation, ledger registration, and trading matching to certificate issuance and regulatory compliance monitoring. This end-to-end design ensures transparent, auditable carbon credit generation and trading while maintaining expert review and real-time compliance oversight. Fork and customize this diagram on Diagrams.so to adapt the platform for other emission reduction methodologies or regional carbon markets. The modular structure separates methodology governance from trading operations, enabling independent scaling of each subsystem.
