The price of a litre of petrol reached €2 for the first time yesterday, as Russia's invasion of Ukraine intensifies.
AA Ireland predicted the milestone before the conflict began.
It says every 10 cent rise in the cost of petrol or diesel adds 120 euro to the annual cost of running a car.
David Horgan, Managing Director of Petrel Resources, says taxes must be reduced to ensure public access to fuel.
"Retail prices that you pay at the pump lags by about 5 or 6 weeks in what happens in the crude market.
"So if you looked at what happened 6 weeks or so ago it was already flowing through the system, because the retailer gets his fuel, adds his 23% VAT and then of course the carbon taxes and excess duties, and the net result is what you pay.
"But remember most of what you're paying is still taxes, including the increasing carbon taxes."
