Plug-in hybrid cars are more polluting than expected according to study

Plug-in hybrid automobiles emit up to five times more CO2 under real driving conditions than calculated by the European Union, according to a study. The research was conducted by the International Council on Clean Transportation (ICCT), an environmental non-governmental organization. The study highlights a significant and growing discrepancy between real CO2 emissions and the measurements during type-approval tests for plug-in hybrid electric vehicles registered between 2021 and a certain unspecified year in the article. The main conclusion indicates that PHEVs are considerably more polluting in practice than the values officially reported to European authorities.
