The Supreme Court on Monday accepted the Centre’s suggestion that vehicles in Delhi and the National Capital Region should display hologram-based stickers to indicate the nature of fuel being used, PTI reported. The court asked the Ministry of Road Transport and Highways, which had made the suggestion, to implement the proposal by September 30.

The ministry told a bench, comprising Justices Madan B Lokur, S Abdul Nazeer and Deepak Gupta, that a light-blue hologram-based sticker can be used for vehicles running on petrol and compressed natural gas while those using diesel can display an orange sticker. The bench asked Additional Solicitor General ANS Nadkarni, representing the ministry, to consider green numberplates for electric and hybrid vehicles. The ministry will soon take a decision on it, said Nadkarni.

Amicus curiae Aparajita Singh had earlier suggested that colour-coded stickers should be used to identify the nature of fuel being used. The lawyer made the observation when the court was hearing a petition on air pollution in New Delhi.
