Every winter, smog settles across North India, burning people’s eyes, making them cough, and increasing hospital visits. The pollution comes from vehicles, burning landfills, crop stubble fires, and other sources.

About 25% of these fumes are from indoor open cooking fires.

The World Health Organisation is hosting its first conference this week to figure out how to protect people from toxic air—including emissions from open cooking fires.

This is a story about global efforts to cut down indoor air pollution—which kills over 3.8 million people annually—and how things got a little twisted along the way.


Dotted with chrysanthemum and rose farms, the tiny hamlet of Parvathapura on the outskirts of Bengaluru, is where we begin our journey, in the cheerful yellow house of M. Anjalidevi. Anjalidevi is the head of the local women’s self-help group, helping its members secure loans for entrepreneurial ventures.

Anjalidevi also facilitates the sale of products that’ll improve women’s lives. “We sell solar lights, gobar gas setups, and the Green stove,” she says. The stove is the reason for our visit, so Anjalidevi sends her son to fetch one from a neighbour’s house. It’s basically a metal cylinder that burns less wood and emits less smoke than the closest alternative, the traditional mud stove, or chulha.

Parvathapura’s women are low-to-middle-income, smack-dab in the key demographic of Greenway Appliances—the stove’s manufacturer. They can afford the Rs 60 ($0.81) weekly payments until the Rs 1,360 ($18) stove is paid off. In fact, they are wealthy enough to switch to a modern stove that burns liquefied petroleum gas (LPG).

So why buy a wood-burning stove? A few reasons. It’s portable and can be used outdoors. Also, Ragi mudde—a local delicacy—tastes better on firewood. It is an ancillary cooking device for them, much like the microwave is for city dwellers.

At the other end of the country, Julie Devi lives in an urban slum of migrants on the outskirts of Patna. She sits outside her dingy single-room house, a 5-month old infant, eyes ringed with kohl, at her breast. She points at her cookstove—a chulha. The awning above it is blackened with soot.

But that isn’t what we’re here to see. We’re here for her advanced cookstove. She points at a black cylinder, brand name “Envirofit”, donated by a local non-profit. The Rs 1,800-stove ($25) broke a year ago, she said. Perhaps she didn’t use it as it was meant to be used.

Greenway and Envirofit are two of hundreds of companies selling advanced stoves that burn wood, animal dung, agricultural byproducts and other biomass.

What is The Ken?

The Ken is a subscription-only business journalism website and app that provides coverage across two editions - India and Southeast Asia.

What kind of stories do you write?

We publish sharp, original and reported stories on technology, business and healthcare. Our stories are forward-looking, analytical and directional — supported by data, visualisations and infographics.

We use language and narrative that is accessible to even lay readers. And we optimise for quality over quantity, every single time.

What do I get if I subscribe?

For subscribers of the India edition, we publish a new story every weekday, a premium daily newsletter, Beyond The First Order and a weekly newsletter - The Nutgraf.

For subscribers of the Southeast Asia edition, we publish a new story three days a week and a weekly newsletter, Strait Up.

The annual subscription will get you complete, exclusive access to our archive of previously published stories for your edition, along with access to our subscriber-only mobile apps, our premium comment sections, our newsletter archives and several other gifts and benefits.

Do I need to pay separately for your premium newsletters?

Nope. Paid, premium subscribers of The Ken get our newsletters delivered for free.

Does a subscription to the India edition grant me access to Southeast Asia stories? Or vice-versa?

Afraid not. Each edition is separate with its own subscription plan. The India edition publishes stories focused on India. The Southeast Asia edition is focused on Southeast Asia. We may occasionally cross-publish stories from one edition to the other.

Do you offer an all-access joint subscription for both editions?

Not yet. If you’d like to access both editions, you’ll have to purchase two subscriptions separately - one for India and the other for Southeast Asia.

Do you offer any discounts?

No. We have a zero discounts policy.

Is there a free trial I can opt for?

We don’t offer any trials, but you can sign up for a free account which will give you access to the weekly free story, our archive of free stories and summaries of the paid stories. You can stay on the free account as long as you’d like.

Do you offer refunds?

We allow you to sample our journalism for free before signing up, and after you do, we stand by its quality. But we do not offer refunds.

I am facing some trouble purchasing a subscription. What can I do?

Please write to us at support@the-ken.com detailing the error or queries.
