Green Firecrackers

Context:

The Supreme Court of India has recently modified its long‑standing prohibition on firecrackers in the Delhi‑NCR region by permitting limited sale and use of green crackers during Diwali 2025 under stringent conditions.

Background:

    • In earlier years, there was a blanket ban on sale, manufacture, and bursting of firecrackers in Delhi‑NCR to curb pollution, backed by multiple Supreme Court and NGT orders.
    • The concept of green firecrackers—low‑emission variants developed and certified by CSIR‑NEERI—has been floated as a compromise to allow fireworks while mitigating environmental damage.
    • Prior orders allowed manufacturing of green crackers (for certified manufacturers) but barred their sale in Delhi‑NCR.

About Supreme Court’s Latest Order:

The Supreme Court has now relaxed the ban with a carefully calibrated framework:

About Green crackers:

Green crackers are a scientifically developed alternative to conventional firecrackers, designed to reduce air and noise pollution during festive celebrations.
