"They found real-world carbon dioxide emissions from PHEVs in 2023 were 4.9 times greater than those from standardised laboratory tests, having risen from being 3.5 times greater in 2021. Real-world emissions are going up, while official emissions are going down, said Sofia Navas Gohlke, a researcher at Transport and Environment and the co-author of the report. This is the gap that is getting worse and it is a real problem."
"The researchers attributed most of the gap to overestimates of the utility factor the ratio of miles travelled in electric mode to the total miles travelled finding that 27% of driving was done in electric mode even though official estimates assumed 84%. The European Commission has announced two corrections to the utility factor ratio that will narrow the gap but not close it entirely, according to the analysis."
"The cars, which can run on electric batteries as well as combustion engines, have been promoted by European carmakers as a way to cover long distances in a single drive unlike fully electric cars while still reducing emissions. Data shows PHEVs emit just 19% less CO2 than petrol and diesel cars, an analysis by the non-profit advocacy group Transport and Environment found on Thursday."
Onboard fuel meter data from 800,000 European cars (2021–2023) show PHEVs emit far more real-world CO2 than laboratory tests indicate. Real-world carbon dioxide emissions from PHEVs reached 4.9 times laboratory-test estimates in 2023, up from 3.5 times in 2021. PHEVs now emit only about 19% less CO2 than petrol and diesel cars, versus a 75% reduction assumed under lab tests. The largest cause is an overestimated utility factor: 27% of driving occurred in electric mode versus an assumed 84%. Electric mode still involved fossil-fuel engine use for nearly one-third of those distances.
