CO2 Emissions Based VRT
Finance Act 2008 changes to Vehicle Registration Tax (VRT)
Since 1 July 2008 VRT is no longer based on the engine size but rather on the CO2 emissions from the car. This is a fundamental change in the method of charging VRT and impacts on the amount of VRT charged on all new cars on sale in the State and also on second-hand cars imported from abroad. Linking the VRT rates to CO2 emission levels means that those purchasing cleaner, low emission cars pay less VRT while those opting to purchase higher emitting vehicles pay more.

It should be noted that the changes in VRT will have no impact on passenger (category A) vehicles already registered in the State as VRT is a once-off tax charged on the registration of the vehicle.
The Department of the Environment, Heritage and Local Government is also changing the way in which annual Motor Tax will be charged. Their website can be found at www.environ.ie![]()
