10 most Eco-Friendly Cars

As the world embraces cleaner air and less pollution, the need for eco-friendly cars becomes the smartest decision and new order.

Currently, pure-electric vehicles or all-electric vehicles (AEVs), plug-in electric vehicles (PEVs), and hybrid EVs are very popular eco-friendly cars. This is because these vehicles produce zero to very low carbon emissions and do not cause as much environmental pollution as the all-petrol vehicles.

However, buying an eco-friendly car doesn’t mean you have to buy an EV –that isn’t a bad move though. There are lots of gas/petrol- and diesel-powered vehicles that are eco-friendly by all standards.

With eco-friendly cars, you’re not only saving the environment but you’re also saving your pocket as you won’t have to pay road tax or congestion charge (if you’re in London).

Purchasing an environmentally-friendly car is a smart decision but also a serious investment as the eco-friendly car market is still in its infant stage – though growing steadily.

So you need to ensure that the “eco-friendly car” you’re purchasing indeed has a history and positive review of environmental-friendliness and is generally respected in the car industry. If you love eco-friendly lifestyle, here is a list of 20 most eco-friendly cars in 2021 you can choose from:

As stated above, the Peugeot 308 has a new 1.5L BlueHDi diesel engine just like the Peugeot 508 model. The amazing fact is that the diesel engine meets the Euro 6.2 standard with low carbon emission.

The car is compact and clean with an official fuel economy of 78.5mpg. However, the Peugeot 308 can’t live up to the official fuel economy figure. According to the independent Equa Index, expect an mpg of about 51 in normal driving.


As stated above, EVs are not the only eco-friendly cars. There are many petrol/gas- and diesel-powered cars out there that also claim to be eco-friendly.

Eco-friendly cars will not only ensure low emissions of carbon dioxide (CO2) but also offer excellent fuel economy, which will save your spending. Aside from the reduction in CO2 emission, eco-friendly cars also release low levels of tiny soot fragments called particulates and the toxic gas nitrogen oxides (NOx), which have been linked to early deaths.

Most eco-friendly cars are hybrid vehicles. Some hybrid cars have a petrol or diesel engine with batteries and a motor. Some are plug-in models, fitted with larger batteries that can be charged to provide about 20miles of all-electric driving before the engine is engaged.
