In January 2025, the Central Pollution Control Board (CPCB) reclassified Waste-to-Energy (WTE) plants under a newly introduced 'blue' category of industries. This change, framed as part of “essential environmental services,” signals a significant policy shift, one that many experts fear could normalise a polluting technology under the garb of progressive waste management. At first glance, the revised classification system seems technical and benign. But behind the bureaucratic language lies a fundamental question: how can an industry once categorised as 'red', the most hazardous tier, suddenly become 'blue', a category reserved for supposedly cleaner, essential services? What does the classification system…

India is running out of landfill space, and governments across cities are increasingly pushing Waste-to-Energy (WtE) plants as the solution. On paper, these plants promise a win-win: burning non-recyclable waste to produce electricity, while reducing the burden on overflowing dumpsites. But the ground reality tells a different story. WtE plants in India face five big problems: They are inefficient because waste in Indian cities is low-calorie and poorly segregated, WtE plants pose serious health and environmental hazards, They are financially unviable WtE systems undermine recycling efforts They do not support a circular economy and threaten the livelihoods of waste pickers.…

Mumbai recently witnessed unprecedented protests that brought its road and rail services to a standstill, disrupting daily life. Around 60,000 protesters from across Maharashtra converged in the city between August 29 and September 2, demanding Maratha caste reservations under the Other Backward Class (OBC) category. For five days, protestors blocked trains and roads, affecting lives and livelihoods across the metropolis. As the capital and political nerve centre of Maharashtra, Mumbai regularly draws protestors from all corners of the state. This is especially true around Azad Maidan, the city’s designated protest site. Those residing and working in South Mumbai, where the…

As of September 2nd, 2025, Bengaluru transitioned into a new urban governance system based on the Greater Bengaluru Governance Act, 2024. This Act implements a three-tier structure: The Greater Bengaluru Authority (GBA): It is chaired by the Chief Minister and comprises all Karnataka ministers and Members of Parliament, Members of the Legislative Assembly and Council from Bengaluru, as well as the mayors of the five newly formed City Corporations. Its primary role is to harmonise planning, development, and service delivery by all the departments and agencies across the five City Corporations. Five City Corporations: The city is divided into five smaller…

The Shakti Yojane has recently crossed 500 crore tickets in the two years since it was launched by the Karnataka government in June 2023. The scheme offers free rides to women (including transwomen) in ordinary public buses, as long as they have a valid ID. Despite the milestone, the Shakti scheme has been at the forefront of political debate in the state. Opposition parties have labelled it a ‘scam’ that “betrays the people.”  A common argument is that male passengers are disproportionately burdened by Shakti, as they have to pay for tickets while women’s travel is fully subsidised.  This criticism…

Every day, India throws away enough plastic to fill 65 Olympic-sized swimming pools. Around 60% of this comes from the packaging industry—chip packets, bottles, polythene covers, and multi-layered wrappers. Managing this mountain of waste is a challenge, and the government hopes to address it with the Draft Plastic Waste Management (Second Amendment) Rules, 2025. You can read the amendment notification here. The changes mostly address Extended Producer Responsibility (EPR). Simply put, it makes companies—manufacturers, brand owners, and importers—accountable for collecting and recycling the plastic they generate. The new rules also set targets for including recycled plastic in packaging: from 30%…

Mumbai's P/North Ward is a climate paradox. On a map, it looks green, boasting significant cover from the Sanjay Gandhi National Park to the east and vital mangroves to the west. Yet, the reality on the ground for its nearly one million residents is one of scorching heat. The surfaces people walk and live on have heated dramatically, with land surface temperatures soaring by over 5°C in much of this ward between 2015 and 2024. The reason is a familiar story of urban expansion: rapid, unplanned growth has replaced cooling ecosystems with a dense fabric of concrete, tin, and asphalt,…

Waking up to the sound of waves crashing against the shore and enjoying a panoramic view of the sea from your high-rise balcony. It's the kind of lifestyle promoted by real estate brochures, luring home buyers with properties steps away from the beach. But what about the impact of indiscriminate development along the coastline? Coastal areas are delicate ecosystems that bear the brunt of unchecked urban expansion. This development often comes at the cost of mangroves, sand dunes and delicate marine habitats. Recognising this looming threat, the Government of India introduced the Coastal Regulation Zone (CRZ) guidelines. These are specifically…

Mumbai's M/East Ward, a sprawling peripheral area including Mankhurd, Govandi, Deonar, Trombay and Chembur, embodies a tale of two cities. It is a vital economic engine, home to major industrial facilities such as the Bhabha Atomic Research Centre (BARC), Tata Power, RCF and HPCL. At the same time, it lies on the city's fringe where its unseen have been pushed over decades, from the mountains of waste at the Deonar landfill to the marginalised communities resettled in its cramped colonies. Our study on the impact of rising urban temperatures reveals just how this deep-seated inequality is baked into the very…

As Indian cities expand at an unprecedented pace, the consequences of rapid urbanisation are becoming increasingly visible: frequent flooding, water scarcity, heat stress, and the loss of natural ecosystems. Once-porous landscapes are now sealed with concrete, leaving rainwater with nowhere to go but into overburdened drainage systems. Even moderate rainfall events can now bring cities to a standstill. In this context, nature-based solutions, such as sponge parks, offer a timely and practical response to India’s urban challenges.  What is a sponge park? Sponge parks are engineered wetlands designed to absorb, store, filter and slowly release rainwater, mimicking the functions of…
