Misleading Plug-in Hybrid Emissions Figures Risk Cheating Consumers, T&E Warns
AI-summarised brief · reviewed before publication
Transport & Environment (T&E) warns that the gap between official CO₂ figures for plug‑in hybrid electric vehicles (PHEVs) and their real‑world emissions is widening, with 2024 models emitting about six times the reported amount. The discrepancy adds roughly €680 to the average driver’s annual fuel cost and means PHEVs are only 14% cleaner than conventional cars, despite test data suggesting an 83% reduction. The EU plans to adjust the “utility factor” – the assumed share of electric driving used in emissions calculations – with a correction slated for November 2026. T&E says the 2025/26 adjustment already prompted manufacturers, notably VW, to increase battery size and electric range, offsetting most of the official emissions rise. The group urges governments to keep the upcoming correction in place to prevent further consumer overcharging and to push genuine improvements in PHEV efficiency.
💡 Why It Matters
- · Without the correction, EU emissions data will continue to understate PHEV fuel use, inflating carmakers’ compliance numbers while drivers shoulder higher costs and Europe’s oil dependence persists.
