IISc Study Finds Flaws in Swachh Vayu Sarvekshan Air Quality Ranking Framework
A technical review by the Indian Institute of Science's Sustainable Transport Lab has criticized the Swachh Vayu Sarvekshan air quality ranking framework for significant methodological flaws. The report highlights conflicts of interest, as urban local bodies self-assess without independent verification, and notes discrepancies between high rankings and poor actual air quality, such as in Lucknow. It also points out omissions of key pollution sources and misaligned scoring. The researchers have recommended scrapping or revising the framework and have communicated their findings to the Union Environment Minister.
