"Many owners love PHEVs because they provide the ease of use of a gas engine with greater fuel economy and, in theory, far fewer emissions than a purely fuel-powered car. And automakers say PHEVs can be a remarkably useful tool in reducing emissions when the switch to EVs is proving harder than expected. However, this study indicates that PHEVs emit five times more carbon dioxide into the atmosphere compared to the official figures published by automakers."
"According to the EEA report, which is based on data transmitted from over 127,000 on-board fuel consumption meters fitted to PHEVs registered in 2023, the real-world emissions of the observed fleet were 139 grams of CO2/kilometer, while the official WLTP-rated emissions should have been 28 g CO2/km. By comparison, PHEVs registered in 2022 had real-world emissions that were four times higher than the official figures, with 137 g CO2/km observed, while the average WLTP emissions were rated at 33 g CO2/km."
EEA data from over 127,000 on-board fuel consumption meters fitted to PHEVs registered in 2023 show observed fleet emissions of 139 g CO2/km versus WLTP-rated 28 g CO2/km. Observed emissions for PHEVs registered in 2022 were 137 g CO2/km compared with WLTP 33 g CO2/km, and 2021 vehicles averaged 134 g CO2/km observed versus 38 g CO2/km official. The gap between official WLTP figures and real-world performance widened despite WLTP-rated emissions falling over time. Discrepancies arise from how official fuel consumption is calculated and from real-world charging and driving behavior that limits electric-mode use.
