U.K. Environmental Secretary Michael Gove is calling for all hybrid cars in the region to be banned by 2040.

According to the plan, any new vehicle that does not have a 50-mile all-electric range would be banned. The proposal, with feedback from the Department of Business, is expected to impact as much as 98 percent of all vehicles sold, excluding cars using petrol engines as backup power.

So far, it has met resistance from the Department for Transport, citing the target as unrealistic and warning against poor messaging in future bans that could confuse consumers.

“We cannot support ambition levels which do not appreciate how industry, the consumer or the market operate and which are based neither on fact nor substance,” said Mike Hawes, chief executive of industry body SMMT. “Unrealistic targets and misleading messaging on bans will only undermine our efforts to realize this future, confusing consumers and wreaking havoc on the new car market and the thousands of jobs it supports,” he added.

The Department of Transport also dispute the reports, citing a policy not to comment on incomplete proposals.

“It is categorically untrue that Government is planning to ban the sale of hybrid [and plug-in hybrid] cars in the U.K. by 2040,” stated the department.

In addition to Gove’s proposed “Road to Zero” policy, the U.K. has rolled out a series of governmental initiatives to fully adopt self-driving cars by 2021. This includes $266-million (£200-million) in development grants towards Automated and Electric Vehicles Bill initiatives, as well as policy setting, redrafting insurance laws, and changes to the Highway Code to accommodate the technology.
