Dr. Kelly de Bruin:

I understand that many vulnerable groups will be challenged by an increase in the carbon tax, but what proportion the increase actually is should be considered. Even if we increased the carbon tax to €80 per tonne, that would correspond to a 10% increase in energy prices. It is not that energy prices will suddenly double on budget day. Small, incremental increases can initiate changes in behaviour that can be later supported by other schemes. It is important to consider that prices will not suddenly double tomorrow.
