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.
That’s a 100% change, not a 20% change. A 20% change would reduce the oxygen by 20%, to around 16%. You’re confusing percentages with percentage points.
Or reduced nitrogen by 20% from the example room to an ordinary one.
He added 25% and called it 20%. Big deal. The topic is PHEVs.
