I am advised by Revenue that its Ready Reckoner for calculating the impact of potential changes in rates of taxation can be used to estimate the effect of changes to the carbon tax rate by extrapolating from the information on page 23. The Ready Reckoner is available on the Revenue website at: www.revenue.ie/en/corporate/information-about-revenue/statistics/ready-reckoner/index.aspx.
An update of the Ready Reckoner is due to issue in the coming weeks. These estimates assume no behavioural changes as a result of price changes.
