Plug-in Hybrids Pollute Almost As Much As Petrol Cars, Report Finds

Plug-in hybrid electric vehicles (PHEVs) pump out nearly five times more planet-heating pollution than official figures show, a report has found. The Guardian: 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. Under laboratory tests, they were assumed to be 75% less polluting.

The researchers analyzed data from the onboard fuel consumption meters of 800,000 cars registered in Europe between 2021 and 2023. They found real-world carbon dioxide emissions from PHEVs in 2023 were 4.9 times greater than those from standardized laboratory tests, having risen from being 3.5 times greater in 2021.
