How much a business parking permit costs

Low emission is defined as a vehicle (not a diesel vehicle) that produces 110g/km or less CO2 emissions.  

Vehicles registered before March 2001 do not show CO2 emissions and therefore do not qualify for a discount. 

Normal emission is defined as a petrol vehicle producing between 111g/km - 165g/km CO2 emissions or a diesel vehicle producing up to 165g/km CO2 emissions.  

High emission is defined as any vehicle that produces 166g/km or more CO2 emissions.
