EU data shows PHEVs emit 350% more CO2 than tested values

Why real-world PHEV emissions exceed test values

  • Main explanation in the thread: test cycles assume frequent charging and high electric driving share; many owners treat PHEVs like regular hybrids or ICE cars.
  • Company-car usage is singled out: studies cited that only ~11–15% of company PHEVs are regularly charged vs ~45–49% of private ones.
  • Some argue PHEVs still emit ~40% less CO₂ than comparable non-hybrids; the 350% figure is “vs assumptions,” not vs ICE.

Charging behavior and infrastructure

  • Many posters say they would charge but lack convenient options: street parking, no home plug, scarce or distant public chargers, or need to move the car when charging completes.
  • Others report dense, app-managed public charging (with reservations and real-time status) and say EV ownership without a garage is feasible.
  • Public charging is often costlier than home charging; in some places it erases the economic advantage over gasoline.
  • Small PHEV electric ranges (often ~30–60 km, less in winter) mean daily plugging is needed for commutes, which many find too much hassle.

Incentives, taxation, and “greenwashing”

  • Several comments describe PHEV subsidies and tax breaks (notably in Germany) as poorly designed: large purchase subsidies, reduced “benefit in kind” taxation, and lower vehicle taxes.
  • This leads to anecdotes of leased PHEVs returned with unused charging cables.
  • Critics call this a legal “tax scam” or greenwashing that mostly benefited affluent buyers and may have had a net negative environmental effect.
  • Others note hybrids’ efficiency gains (regenerative braking, reduced idling) and argue they are still better than pure ICE.

Policy, alternatives, and broader transport issues

  • WLTP testing for PHEVs is criticized as overly optimistic; new EU rules are said to raise official PHEV emission figures.
  • One biogas car owner highlights inconsistent policy: very low real emissions but higher taxation than PHEVs, because law assumes fossil gas and ignores biogas.
  • Debate extends to public transport and urban design: some push for less car use in cities; others stress rural dependence on cars and need for “middle ground.”
  • Carbon‑neutral fuels are mentioned but viewed as currently impractical or nonexistent in meaningful volumes.
