The increasing urgency of climate change has thrust carbon credit markets into the limelight as vital tools of global emission management strategies. Yet, chronic fraud, price manipulation, lack of transparency, and verification bottlenecks continue to undermine their credibility and scalability. This research investigates how artificial intelligence (AI), specifically machine learning (ML) and natural language processing (NLP), has the potential to transform the effectiveness, fairness, and integrity of carbon trading processes. A novel AI-driven Trust Index is introduced, incorporating anomaly detection, dynamic price forecasting, and NLP-driven document quality scoring within a single framework. Using large datasets from Verra, Gold Standard, the EU Emissions Trading System, and blockchain-based exchanges, AI models were created, tested, and piloted in a simulated carbon registry environment to determine real-world feasibility. Results demonstrate that ML models achieved 78% fraud detection correlation, price prediction accuracy with R² of 0.89, and 92% project documentation classification accuracy. Alongside technical performance, the study foregrounds ethical AI design through the integration of bias auditing, cultural sensitivity, and explainability mechanisms to facilitate equitable evaluation across Global South and community-based projects. The Trust Index model dramatically improves transparency, lowers due diligence expenses, and boosts buyer confidence, and proposes a new direction for scaling up high-integrity carbon markets. For all its revolutionary potential, real-world obstacles like data access fragmentation, institutional inertia, and the need for human oversight remain. Finally, this study presents a strategic, action-oriented agenda to policymakers, market actors, and registries to responsibly harness AI for carbon finance infrastructure, paving the way towards a more credible, inclusive, and climate-just future.
