Macro monitoring and early warning evaluation of environmental protection of industrial economy under the target of carbon neutrality

The article proposes the digitised carbon neutrality blockchain technology (DCN-BT) system, which combines blockchain and AI-driven sensor data to monitor industrial emissions in real-time. DCN-BT makes data more transparent, improves early warning accuracy to 97.43%, reduces industrial carbon intensity by 50%, and achieves 5% annual energy saving. DCN-BT creates a scalable, data-driven solution to balance economic growth with environmental sustainability by fusing multi-sensor data with blockchain validation. This proposed system helps governments and industries achieve carbon neutrality utilising advanced digital technologies that ensure efficient carbon tracking, predictive analytics, and better decision-making.
