Environmentally friendly or polluting? PHEV car busted, 5 times more pollution than expected in test, shocking ICCT report

According to a recent report by the International Council on Clean Transportation (ICCT), the actual CO₂ emissions of plug-in hybrid vehicles can be on average five times higher than those reported in official tests. This is important because PHEVs (plug-in hybrid electric vehicles) have long been promoted as a low-emission technology.

Official statistics

The report found that vehicle manufacturers and testing organizations typically test PHEVs under ideal conditions. During these tests, the battery is fully charged and the vehicle is driven in electric mode most of the time. This is why the emission figures look significantly lower. But the daily situation is different. Many drivers do not charge their cars regularly, leading to greater dependence on petrol engines. This can lead to a significant increase in actual emissions.

Charging habits determine real benefits

Experts say the success of plug-in hybrid technology depends largely on the charging habits of vehicle owners. If the driver regularly charges the battery and travels most of the distance in electric mode, emissions can actually be significantly reduced. However, when the battery is not charged, the PHEV behaves almost like a normal petrol car. This situation increases both fuel consumption and CO₂ emissions.

Are electric vehicles becoming a better option?

After the ICCT report, many experts and policy makers are now considering battery electric vehicles (BEVs) as a more effective solution. BEVs run entirely on electricity and emit no tailpipe emissions when driven. This is why electric vehicles are now becoming more preferred in many countries, while the benefits and incentives for plug-in hybrid vehicles have begun to be reviewed.

Under review in many markets including Europe

Following the report, subsidies and incentives for plug-in hybrid vehicles are being reconsidered in several major automobile markets, including Europe. Policymakers are checking whether these vehicles are actually helping to achieve environmental goals.
