New Delhi: An expert committee constituted to suggest measures for curbing vehicular emissions in Delhi-NCR has recommended the immediate exit of BS-I, II and III vehicles, while proposing that BS-IV vehicles go by 2030, BS-VI two-wheelers by 2035 and BS-VI four-wheelers by 2040. It said that from Jan 1, 2031, no new ICE private four-wheeler vehicle should be allowed to be registered.
Last Dec, Commission for Air Quality Management (CAQM) set up the 15-member committee to recommend a multi-pronged roadmap for emission reduction in the vehicular sector. The interim report, which was submitted to CAQM on Aug 18, was shared Wednesday. The report said the active and fitness-approved fleet across Delhi-NCR comprised 2.2 crore vehicles, of which electric vehicles (EVs) accounted for only 3.6 lakh, or 1.6%.
The report is being considered,” an official said.
“We previously ordered phasing out of light goods vehicles and three-wheelers based on it.
For phasing out existing internal combustion engine (ICE) vehicles, the exit timelines are similar to Delhi EV Policy 2026.
the recommendation is technology-neutral, leaving room for other ZTE technologies, such as hydrogen fuel-cell vehicles, as they become viable in the future,” said a committee member While EVs are currently the available ZTE option. Vehicles phased out from Delhi-NCR should not simply migrate to other cities in the Indo-Gangetic plain,” said the report. “Mechanisms should be devised to prevent the transfer of high-emitting vehicles from Delhi-NCR to other highly polluted regions.”
“The report recommended accelerating the transition to ZTE vehicles. “Similar principles could be considered across the Indo-Gangetic plain, given the contiguous transboundary nature of air pollution.
