Digital trade openness injects new momentum into global green trade, leveraging innovations like blockchain for carbon footprint tracking and AI for green logistics optimization to significantly enhance efficiency and industrial value. Blockchain ensures real-time carbon data recording across supply chains, addressing cross-border carbon accounting trust issues, while AI optimizes logistics for low-carbon supply chains. However, digital divides, technical barriers, and high transition costs for SMEs hinder inclusive growth. A balanced digital trade system is needed to remove barriers, strengthen policies, lower SME transition thresholds, and promote green technology industrialization for sustainable global green trade.
