LondonUK carmakers claimed zero-emission vehicle demand was too low.
The mandate’s built-in flexibilities pushed UK compliance to 24.5% in 2024, 2.5 points above the 22% target, government data show.
The car industry is lobbying for an urgent mandate review, claiming natural demand remains too weak.

WHAT THE MANDATE DOES
The Zero Emission Vehicle mandate, in force since January 2024, requires each carmaker to ensure a rising share of its UK new-car sales are battery-electric — 22% in 2024, climbing to 80% by 2030 and 100% by 2035. Miss the share and you owe £15,000 per non-compliant car.
THE FLEXIBILITIES
Three escape valves dilute the headline target. Carmakers can borrow allowances from future years, bank surpluses from past years, and earn credits by cutting CO2 from their petrol and diesel fleet. After all three, real BEV sales were only ~19.6% — but reported compliance hit 24.5%.
WHY THE INDUSTRY LOBBIES
Every BEV sold below cost is a margin hit; every petrol car sold above the implicit cap is a £15,000 fine. Carmakers want the curve flattened or the 2030 phase-out delayed — the framing of weak demand is the lobbying vehicle, not the underlying complaint.
THE EU PARALLEL
The EU runs fleet-average CO2 limits rather than a BEV quota — same destination, different lever. Brussels softened its 2025 target in early 2025 after similar industry lobbying, allowing a three-year averaging window. London's mandate is now the stricter regime in Europe.
THE DEMAND QUESTION
Private retail BEV demand in the UK is genuinely soft — most BEVs are sold to fleets and salary-sacrifice schemes that capture the tax break. The mandate works because it forces supply: discounts, lease deals, and model launches appear when carmakers need to shift the mix, not when consumers spontaneously ask.
