CO2 Rankings For Cars

When you see a billboard advertising a certain car, does it prominently feature the grams/km of CO2 emissions? When you see used car ads in the back of the Coventry Telegraph, do they mention the grams/km of CO2 emissions?

When we start seeing these indicators, that's when the tide will be turning.

You can check which models of cars have what levels of grams/km here.

The leading petrol model remains the Toyota Prius (104 g/km), followed by a chasing group of the following models: the Peugeot 107, the Toyota Aygo, the Citroen C1, and the Honda Civic hybrid (all at 109 g/km).

Technically, the Volkswagen Polo BlueMotion has 99 g/km, but it's diesel (diesel particulates and nitrogen oxide increase lung cancer and cardiac diseases, and make existing conditions, like asthma, worse).

In contrast, large 4x4s (petrol) start with the Lexus RX (192 g/km), then the Hyundai New Santa Fe (252 g/km ... where do they get these names).
