Greenhouse Gas Emissions (GHG)

The legislative emission standards for South Africa are Euro 2 fuels. It is planned that South Africa will move from the current Euro 2 emission standards to the Euro 5 level in 2017.

Carbon dioxide emissions (CO2)

207 grams of carbon dioxide per kilometer.
This uses Euro 2 average cars, using unleaded fuel while driving on a motorway, as the average. This average is calculated by taking into consideration both emissions from a petrol (206g/km) and diesel (208g/km) car.

Nitrogen oxides emissions (NOx)

565.6 mg of nitrogen oxides per car kilometer.
This uses Euro 2 average cars, using unleaded fuel while driving on a motorway, as the average. This average is calculated by taking into consideration both emissions from an average-sized petrol (316.2 mg/km) and diesel (815 mg/km) car.

Carbon monoxide emissions (CO)

243.5 mg of carbon monoxide per car kilometer.
This uses Euro 2 average cars, using unleaded fuel while driving on a motorway, as the average. This average is calculated by taking into consideration both emissions from an average-sized petrol (411 mg/k ) and diesel (76 mg/km) car

Particulate matter emissions (PM)

31.85 mg of particulate matter per car kilometer.
This uses Euro 2 average cars, using unleaded fuel while driving on a motorway, as the average. This average is calculated by taking into consideration both emissions from an average-sized petrol (5.4 mg/km) and diesel (58.3 mg/km) car

Hydrocarbons (C) + (H)

26.9 mg of total hydrocarbons per car kilometer.
This uses Euro 2 average cars, using unleaded fuel while driving on a motorway, as the average. This average is calculated by taking into consideration both emissions from an average-sized petrol (28.4 mg/km) and diesel (25.4 mg/km) car.
