Why is the benzene level in petrol level being reduced?
Benzene is a known human carcinogen. Reducing the benzene content in petrol to 1% of volume is aligning with international best practice for benzene content in petrol. The higher the benzene content in petrol the higher the emissions of benzene produced, generally as a result of evaporative emissions from the vehicle fuel system. Generally vehicle exhaust catalysts are very effective at reducing the benzene content in vehicle exhausts to very low levels.
