The speed limit on Irish motorways could be reduced as part of the Green Party's proposals to reduce carbon emissions.
During negotiations on the Programme For Government, the party examined the impact of cutting the 120 km/h speed limit for cars and trucks to 110 km/h.
As reported by the Business Post, the move would lengthen travel times but the party believe it would improve fuel consumption for those who drive close to top speed.
The measure is not included in the Programme for Government, however, the programme did commit to a review on speed limits.
Cork City Green Party Councillor Dan Boyle says it is just one of a number of suggestions for reducing carbon emissions.
He said: "We need to get people thinking about the level of speed we use on our roads.
"There are road safety concerns, of course, but the faster we go the more we use our fuel, and fuel itself creates carbon emissions.
He added: "As a country, we have continuing problems with carbon emissions so as part of a package of measures to reducing carbon emissions across the country, how fast we go and how often we travel and how are issues we need to address."
