Holographic Stickers to Fight Air Pollution

The Supreme Court of India is considering making hologram-based, colour-coded stickers (HCCS) for vehicles mandatory nationwide. This comes amid growing concerns about pollution, with an increasing trend in the Air Quality Index (AQI) in Delhi, the country’s capital. The court noted that of the approximately 2.7 million vehicles in Delhi, only 1.7-1.8 million had these HCCS, which are crucial for identifying vehicles using sub-par fuel on high-pollution days.
