The forces shaping Ireland’s housing market are about to get a new driver. It’s not interest rates. Not planning laws.
Not migration. It is the jet engine.
New analysis from Transport & Environment, the European clean transport advocacy group, puts a hard number on something renters already sense. By 2031, rents in Ireland could climb an extra €250 a year. That figure sits on top of any other increases.
The study, conducted by the New Economics Foundation, warns that rising rents will “primarily affect lower-income households.” The mechanism is brutally simple. More tourists flying in means more demand for places to sleep.
Hotels fill up. Prices rise. The cost bleeds into the wider rental market.
Ireland is expected to see the largest rent increase of any country studied. The report looked only at formal accommodation — hotels. Data for informal rentals is limited.
The authors note that if the rise in nights spent in informal accommodation, such as Airbnb, were considered, “the growth rates would likely be higher still.” The real figure, in other words, is probably worse. This is not a temporary blip.
Despite widespread “anti-tourism protests” in some popular destinations, the number of tourists arriving by air continues to rise. The underlying trend is upward. And it is global.
The aviation sector is responsible for an estimated 52% of the global tourism industry’s direct emissions. In Europe, emissions from international tourist arrivals by air are projected to rise over 60% between 2016 and 2030.
More flights. More emissions. More tourists.
More rent pressure. Transport & Environment is now calling for a new EU Sustainable Tourism Strategy. The group wants a focus on reducing international air arrivals in saturated regions.
It wants a wider analysis of the impacts of air tourism. The study warned that Ireland and other countries are expanding air travel.
Spain, Italy, Greece, and Portugal are among other European countries facing what T&E calls an “unaffordable housing crisis.” The Spanish have committed €12.9bn to expanding air travel — the report cuts off there, but the direction is clear. Governments are investing in the very infrastructure that drives the problem. What does this mean for a renter in Dublin?
The €250 figure is an average. It will not be spread evenly.
Lower-income households, the study warns, will feel it most. They are the ones with the least slack in their budgets. A €20 monthly increase is not a rounding error when you are already stretching to make rent.
The logic here is uncomfortable. Tourism is sold as economic salvation. But the costs are concentrated.
The benefits spread thin. The hotelier gains.
The airline gains. The renter pays. The person living in a house that could have been a long-term rental, but is now a short-term let, pays again.
There is a structural mismatch. Air travel is cheap.
Carbon is unpriced. Housing is finite. You cannot build your way out of demand that is being inflated by a global industry that does not bear the cost of its own expansion.
The report’s limitation is its own data. It could not measure the informal sector properly. That means the headline number is a floor, not a ceiling.
The actual rent impact, once Airbnb and similar platforms are fully counted, will be higher. The study says so itself.
Ireland is the canary. It faces the largest rent increase of any country studied. If this holds, the pressure on the rental market will intensify.
And the political response — anti-tourism protests, calls for caps, demands for regulation — will likely intensify too. The question nobody in government is answering: do we want more tourists, or do we want affordable rents?
Right now, policy says both. The numbers say otherwise.
