Excerpt:

New research has shown that plug-in hybrid electric vehicles (PHEVs) emit just 19 per cent less CO2 per kilometre on average than petrol and diesel cars in Europe, significantly undermining the claims of carmakers.

According to a new report published by Transport & Environment (T&E), a leading European clean transport and energy advocacy group, PHEVs were shown to emit roughly the same level of emissions as conventional hybrids and combustion vehicles.
