Professor John FitzGerald:

I identified €71 million within an hour. Then, three days later, the Department of Public Expenditure and Reform published a very good note that sets out where all of the €90 million will go. Of course, there is a great deal more in terms of public transport investment and so on. It would help if there was a green budget so that we could see where all of the money is going. My suspicion is that far more than the total revenue from the carbon tax is going on climate change issues, including the SEAI budget, for example. We could do better to help people find out what is being done in this area. While we are not doing enough, it would be better if people knew about what little we are doing.

The Deputy referred to retrofitting and upgrading. It is likely that the households of Ireland will need to spend between €25 billion and €75 billion over the next 30 years.
