Like in the past few years, Delhi’s air quality once again deteriorated with the onset of winter this October. On Tuesday, a thick layer of haze enveloped parts of the national capital, with the Air Quality Index (AQI) remaining in the ‘poor’ category at 294. To tackle the situation, the state government has announced a host of measures, from conducting a new study to identify the sources of pollution in the region and calling for a shift to electric vehicles.

A new report, ‘Different Paths to Clean Air: Global Insights for India’s Reform Agenda’, by Sustainable Futures Collaborative (SFC), a New Delhi-based research organisation, has provided detailed pathways to improve air quality in India, including Delhi, by examining how other countries addressed their diverse pollution challenges. The researchers — Ishita Srivastava, Arunesh Karkun, and Bhargav Krishna — looked at environmental regulatory regimes in Brazil, China, Germany, Mexico, Poland, South Korea, and the United States. These countries were chosen for their relevance to India: large economies, histories of severe air pollution, rapid industrialisation, high GDP growth, and representation from both the Global North and South, according to the report.
