An Indian Express editorial has flagged that Delhi’s Mechanical Road Sweeping Machine (MRSM) fleet remains severely underutilised — even as dust accounts for ~41% of PM10 and ~38% of PM2.5 in the capital’s summer air. The piece calls for a coordinated dust-management strategy, foregrounding the legal and constitutional scaffolding around the right to clean air.
