What Is The Sustainability Mafia? Inside India’s Founder-Led Climate Startup Network

India’s climate startup ecosystem has no shortage of incubators, investors and accelerators. So why did a group of founders decide to create yet another network? The answer, says The Sustainability Mafia co-founder Ganesh Shankar, was that founders were still building largely in isolation.  Today, the Bengaluru-based network brings together founders working across sectors including clean […]

How I Transitioned Into Climate Work Without a Traditional Sustainability Background Bengaluru

How I Transitioned Into Climate Work Without a Traditional Sustainability Background

Looking back, I do not think my journey into climate work began with one defining moment. Instead, it was shaped by a series of experiences that stayed with me over the years, long before I understood what a “climate career” even meant. Some of my earliest memories of engaging with environmental themes come from school. […]

How I Built ReRooted.Films: Creating a Sustainable Production Studio in India

When was the last time you felt rooted? Really rooted. With a sense of belonging to something larger than yourself. A place, a person, a community, maybe even a kind of food. Our roots may begin in one place, but we spend our lives finding ways to grow them elsewhere. We keep searching for ways […]

Off the Charts: What Climate Communicators Can Learn from Data Visualisers

The climate movement has never had more data. Satellites map shrinking glaciers in real time. Sensors record rising temperatures by the hour. Researchers can estimate everything from groundwater depletion to carbon emissions with remarkable precision. Yet much of climate communication still struggles with a fundamental problem: people don’t experience gigatonnes of carbon dioxide. They experience […]

CCUS in India: Essential Climate Solution or a Lifeline for Coal? Dehradun

CCUS in India: Essential Climate Solution or a Lifeline for Coal?

India’s ₹20,000 crore budget allocation to Carbon Capture, Utilisation and Storage (CCUS) announced earlier this year positions CCUS as both a climate solution and a lifeline for India’s coal-dependent economy. This raises a critical question: is this pragmatic decarbonisation, or an expensive way to prolong the fossil fuel era? While allocations for renewable energy in […]

Scientists Test Turning Aquatic Weeds into Liquid Fertilisers

Scientists Test Turning Aquatic Weeds into Liquid Fertilisers

The uncontrolled growth of aquatic plants has become a major environmental challenge in Dal lake, an important freshwater lake in the Kashmir Himalaya. A new study has tested a way to convert these excess plants into fermented liquid fertilisers, offering a potential solution to manage weed overgrowth while producing a useful agricultural input. Dal, a culturally and […]

Dholavira’s Water Wisdom: What a 4,500-Year-Old City Teaches Modern India about Managing Scarcity

Standing atop the massive citadel of Dholavira, a 4500-year-old city, in the arid expanse of Gujarat’s Rann of Kachchh, it is difficult not to be struck by a paradox. This was a city built in one of the most water-scarce landscapes of the Indian subcontinent, yet it flourished for nearly a millennium. Looking down from […]

India Needs More Scrap to Boost Green Steelmaking. But Where Is the Scrap?

India Needs More Scrap to Boost Green Steelmaking. But Where Is the Scrap?

Steel scrap has become an increasingly strategic resource for countries and their steelmakers as a key input for emissions reductions. India, the world’s second largest steel producer, has set ambitious targets to double the share of scrap use in its total steel output in the coming decades. The question is: where is the scrap? Scrap […]

Every time an Indian household backs up its power with a UPS during a blackout, or an e-rickshaw squeezes out one more ride before charging, there is an invisible material working behind the scenes: carbon. Batteries are not just about lithium. Increasingly, the real innovation battleground is around the supporting materials inside batteries, materials that […]

India’s Rivers Need a Dye Detox, and Organic Colour’s to the Rescue
Bangalore

Whenever filmmakers want to portray the raw, uncomplicated beauty of India, two shots often make it to the screen. A crowded city bazaar, with two-wheelers and colourful autorickshaws jostling for space, women wearing vibrant sarees in blue, green, yellow and orange, and children smiling toothily into the camera while waving paper fans. The second shot […]

Is This the World’s Unlikeliest Protein Source?

In India and around the world, methane is leaking into the atmosphere from rice paddies, cattle farms and decomposing waste, accelerating global warming. While carbon dioxide is the most talked-about greenhouse gas, methane is significantly more potent. To understand why, imagine greenhouse gases as blankets covering the Earth. Carbon dioxide adds many thin blankets, while […]

How’s the Green Energy Corridor Coming Along, and Is It Time for Battery Subsidies?

India’s continuing renewables growth curve will not be determined only by how many panels get installed, but on how intelligently demand, storage, pricing, transmission and dispatch are managed.  The country can generate more clean power during sunny hours, but the grid must still serve homes, industries and cities when demand rises later in the day.
