Opposition parties have intensified criticism of the Centre over dangerous air in Delhi after Diwali. Congress MP Jairam Ramesh cited a FICCI-EY study putting India's 2023 pollution-linked deaths at about two million. Congress leader Ajay Maken, citing CPCB data, said 25 of Delhi's 39 monitoring stations logged no PM2.5 readings in the early hours of November 9. Across the nine stations that did report, average PM2.5 was 576 micrograms per cubic metre, up 2.5 percent on the same hour last Diwali.
