The 2030 Ban Is Back. Let Me Explain Why I'm Not Actually Celebrating.

On 4 July 2024, the newly elected Labour government announced it was reinstating the 2030 ban on new petrol and diesel car sales. This is, objectively, the policy position I have wanted for years. The ban was the right policy. I told my wife it was the right policy many times, at length, including on a car journey to Bristol in 2022 that she has asked me not to bring up again.

I am not celebrating. Let me explain.

A brief and increasingly irritating timeline

This timeline is not a cause for celebration. It is a chronicle of damage. The automotive industry runs on 5-7 year planning cycles. Car manufacturers need to know what regulations look like years ahead in order to commit to production lines, supplier contracts, dealer network investments, and model launches. Between October 2022 and July 2024, the UK government told the industry the deadline was 2030, then 2035, then 2030 again. In under two years.

Two Volkswagen executives told trade press in late 2023 that the UK policy reversal had introduced "significant uncertainty" into their market planning. This is corporate language for "you have made our jobs very difficult."

The ZEV mandate: the actual policy doing the actual work

Here's what most reporting on the "2030 ban" misses: the Zero Emission Vehicle mandate is already in force and has been doing more practical work than the headline ban date.

Under the ZEV mandate, 22% of all new cars sold in the UK in 2024 must be zero emission. That figure rises to 28% in 2025, 33% in 2026, escalating to 80% by 2030 and 100% by 2035. Manufacturers who miss their targets face fines of £15,000 per non-compliant vehicle sold beyond quota.

This is the mechanism actually driving change. Not the symbolic ban date. The 2030 figure matters as a signal, but the year-on-year ZEV percentages are what's making manufacturers actually build and discount EVs right now, in 2024. Several manufacturers are already offering substantial discounts on EVs specifically to hit their ZEV mandate numbers. This is directly good for car buyers.

Why the ban may be almost irrelevant by 2030 anyway

Battery costs have fallen roughly 90% since 2010. The upfront price premium of EVs over equivalent petrol cars has been closing steadily. The BYD Seal is already £5,500 cheaper than the equivalent Tesla Model 3 at UK list prices, and the gap between EVs and comparable petrol cars at the mass-market end is shrinking every year.

If battery costs keep falling at anything like their historical rate, EVs will reach cost parity with petrol cars at point of purchase by 2027-2028 for most segments. At that point, the question isn't "are you allowed to buy a petrol car" — it's "why would you?" Running costs are already substantially in EVs' favour. Capital cost parity removes the final barrier.

The 2030 ban, in this scenario, becomes a rule that prohibits something almost nobody would be doing anyway.

I want the ban. I always wanted the ban. I just think the two years of policy vacillation have undermined consumer confidence more than any ban could restore, and that the real story is the economics rather than the legislation. The economics are winning. They are winning regardless of which party is in Downing Street.

My wife, when I explained all of this, said: "So you're happy but not happy?" Yes. Correct. That is exactly where I am.
