Let Diwali shine brighter: Tradition, enterprise and the promise of a greener festival

• A celebration rooted in faith, enriched by local livelihoods and conscious choices

As the autumn air turns crisp and the scent of marigolds begins to drift through the streets, India prepares for its most luminous festival. Diwali arrives with a familiar transformation: homes are swept clean, doorways are adorned with rangoli, families reunite after long separations, and the evening sky seems to acquire a glow of its own.

Across the length and breadth of the country, the festival is celebrated through stories and customs that are not identical, yet they share a powerful, unifying idea—the triumph of light over darkness, knowledge over ignorance, and good over evil. In much of northern India, rows of earthen lamps recall the joyous homecoming of Rama to Ayodhya; elsewhere, Diwali is associated with Krishna's victory over Narakasura, the worship of Lakshmi, or a myriad of other regional and religious traditions. Its history is layered, and its meaning belongs to the communities that keep it alive.

This year, as we look toward Diwali 2026, there is a growing conversation about how we celebrate. A discussion about a greener Diwali must not be an exercise in telling people how to practice their faith, nor should it set devotion against environmental concern. Festivals, by their very nature, evolve as society, technology and circumstances change. The real opportunity before us is to retain the warmth, colour and happiness of Diwali while making choices that are considerate of our neighbours, our workers, our natural surroundings and the generations who will inherit them. A greener Diwali is not a call to celebrate less; it is an invitation to make the celebration more thoughtful and enduring.

The Economics of Light: Supporting Local Livelihoods

Diwali is a major season of spending. From home renovations to new clothes, from gifts to grand feasts, the economic activity generated during this period is immense. However, a portion of that expenditure can be directed to support the backbone of our local economies: potters, artisans, flower sellers, sweet-makers, small shopkeepers, craft cooperatives and women's self-help groups. Such purchases may appear modest individually—a few diyas here, a handcrafted gift there—but together they help circulate money within local markets and strengthen livelihoods that are often seasonal or informal. In rural and smaller urban communities, these activities can provide supplementary income to households that have limited access to formal employment.

A locally made lamp, therefore, carries two forms of light: the visible glow in a home and the less visible support it provides to a producer's household. The diya remains one of the most beautiful ways to express the spirit of Diwali. An earthen lamp, made by a local potter and placed at a doorstep, has a quiet elegance that needs no explanation. Its flame is intimate and welcoming; one lamp can light another without losing its own brightness. The image is also culturally resonant: the lamp is not an imported accessory to the festival but a familiar part of its ritual and visual language. Choosing locally made diyas, natural-colour rangoli materials, flowers, reusable decorations and locally prepared festive foods can connect celebration with the people who sustain traditional skills and local economies.

Navigating the Fireworks Debate: Safety and Substance

The experience of a festival also differs from person to person. For many, fireworks are associated with childhood memories, family gatherings and a sense of occasion. For those who wish to include fireworks in their celebration, the practical course is to follow the applicable local directions and use only products permitted by the authorities. The term "green cracker" should not be treated as a decorative marketing phrase. CSIR–NEERI describes green crackers as products developed with modified formulations intended to reduce emissions; its published criteria include specified reductions in particulate matter and/or gaseous emissions compared with conventional products. Consumers should check authentic product-specific certification and avoid counterfeit claims.

Green crackers are not pollution-free, nor do they remove the need to observe restrictions on timing, location, noise and sale. Reduced emissions are a step in the right direction, not a license for unlimited use. It is essential to understand that the most meaningful form of economic nationalism is the confidence in our own producers, workers, scientists and institutions. Consumers can avoid illicit, unsafe or unlabelled imported fireworks and decorations, and favour legitimate Indian products with transparent safety and compliance information. The point is not to assume that every foreign product is harmful or every domestic product is safe. It is to insist on quality, legality, worker welfare and accountability—and to recognise that local enterprise is strengthened when consumers make informed choices.

A Responsibility to Care

From the perspective of forestry and environmental protection, this is not an instruction to withdraw from life, but a responsibility to care for the conditions that make life possible. The forest, the city, the household and the marketplace are connected. Our traditions have endured because each generation has found ways to carry them forward. We can do the same with Diwali: preserve its faith, warmth, colour, generosity and joy, while choosing practices that are safer for people and gentler on the environment.

This year, let the brightest symbol of Diwali be not the smoke that briefly fills the sky, but the light that remains—in a potter's home, in a woman's small enterprise, in a worker's safer workplace, in a child's clear breath and in the shared spaces we pass on to the next generation. Celebrate with devotion, celebrate with pride, and let the festival of lights truly leave more light behind.
