About

Who publishes this

This site is published by Ajay Maken, Member of Parliament, Rajya Sabha. It is not a neutral third party, and it does not pretend to be one. It is the work of a serving opposition politician who believes the air in Delhi is a public health emergency that has outlasted several governments, including ones his own party led.

We state that plainly at the top of every page for a simple reason. The easiest way to dismiss inconvenient data is to question who is behind it. There is nothing here to discover: the ownership is on the masthead, the method is published in full, the source data is the government's own, and every report can be checked line by line.

Why the name

हवा का हिसाब means the reckoning, or the accounting, of the air. That is what this is: a daily account, kept in numbers, of what Delhi and the wider region are actually breathing, and whether anything anyone is doing about it is working.

The name is deliberately not tied to one city. Air pollution does not stop at a municipal boundary. What Delhi breathes is shaped by stubble burning in Punjab and Haryana, by brick kilns across the region, and by transport and industry throughout the National Capital Region. An honest account has to follow the air, not the map.

What is published here

• A daily report, roughly twelve pages, covering the day's air, every monitoring station, the weather versus policy attribution, and the full year of de-weathered trends.
• A daily bulletin in Hindi, around two minutes, covering the same findings.
• A weekly deep edition, examining wind direction, regional transport, and the longer patterns a single day cannot show.
• Special investigations, published when the data warrants one.

Every report here is free to quote, cite, and republish, with attribution. Journalists, researchers, students, and citizens are all welcome to use it. If you find an error, we want to know: corrections are published rather than quietly made.
