This report assesses the adoption and implementation of Continuous Emission Monitoring Systems (CEMS) across 41 industrial units in Uttar Pradesh. Drawing on industry surveys and site visits, it examines practices across the CEMS lifecycle—from technology selection and installation to calibration, quality assurance, data standardisation and comparison with reference measurements. The assessment identifies significant gaps in implementation, technical capacity, data reliability and regulatory oversight, while also documenting examples of good practice. It proposes a phased action plan for strengthening CEMS-based compliance monitoring in the state and includes a practical checklist to support regulators and industries in assessing implementation gaps and identifying corrective measures.
