New Delhi, Nov. 27 -- The National Green Tribunal-appointed amicus curiae, senior advocate Sanjay Upadhyay, raised urgent concerns over the worsening air pollution in the National Capital Region (NCR). In an affidavit to the tribunal, dated November 6, and released recently, he said that, despite the GRAP being in force, air quality has not improved and emergency interventions such as cloud seeding have delivered no measurable results. The affidavit also highlighted significant discrepancies in official pollution data. Upadhyay pointed to the consistent failure of air quality to improve under Grap measures, noting that "Stage 1 Grap was initiated on October 14, and stage 2 on October 19, 2025. Despite stage 2 Grap orders, the AQI has consistently remained in 'poor' to 'very poor' quality." He identified data quality as a central concern, citing newspaper reports that alleged "tampering with AQI monitor readings by undertaking sprinkling close to AQI monitors and thus reducing the PM level reading by the monitors to mislead and misinform about the severity of the air quality situation". Specific examples included such sprinkling outside the Anand Vihar and RK Puram monitoring stations. Upadhyay asserted that pollution control boards must explain these anomalies, stating, "This appears to be a very serious allegation where human health and the right to life itself are at stake. The Commission for Air Quality Management needs to explain the action taken in this regard."...
