The Portuguese city of Porto — long considered one of Europe's most beautiful and one of its most congested — has launched a scheme that urban planners across the continent are watching closely: free public transport for all residents.
Starting this year, Porto's buses, trams, and trains are entirely free for anyone registered as a resident of the city, under a flagship policy introduced by new mayor Pedro Duarte. The estimated cost of the programme stands at approximately €25 million (around £23 million) per year, which the city council has committed to covering from public funds.
To help pay for it, Porto's administration is considering an increase in the city's tourist tax — effectively asking the millions of visitors who arrive each year to help subsidise the transit system that residents no longer pay for. Porto welcomed more than ten million visitors in 2024, a figure that continues to rise.
A City Struggling with Its Own Success
Porto has long been notorious for congestion. As tourism surged in the 2010s and 2020s, the city's narrow historic streets and limited metro coverage created bottlenecks that frustrated both residents and visitors. Car ownership remained high partly because the bus network, while functional, was not seen as a compelling alternative for daily commuting.
Mayor Duarte framed free transit not merely as a social policy, but as a practical response to urban gridlock. By removing the cost barrier entirely, the scheme aims to shift a significant share of Porto's population out of private vehicles and onto the public network — with knock-on benefits for air quality, noise levels, and street safety.
Building on Portugal's Lead
Porto's initiative builds on momentum already established at the national level. Portugal introduced a free public transport scheme for all citizens under the age of 23 in 2023 — a programme that proved popular and saw youth ridership increase substantially. Porto's new scheme extends that logic to all residents, regardless of age or income.
Portugal is not the first European country to take this step. Luxembourg made all public transport free for everyone — residents and tourists alike — in 2020, becoming the first country in the world to do so. Its experience showed that fare-free transit does increase ridership and reduce car use, particularly when paired with reliable, frequent service.
A Growing Movement Across Europe
Porto joins a growing number of cities and regions across Europe experimenting with free or heavily subsidised public transport. Tallinn, the Estonian capital, made transit free for residents back in 2013. German cities have experimented with ultra-cheap monthly passes. Vienna offers an annual transit pass for just €365 — one euro per day. Madrid subsidises youth fares heavily.
What distinguishes Porto's scheme is its simplicity and scale: every resident, of every age and income, now has full access to the city's transit network without a ticket.
For lower-income households, the benefits are immediate and tangible. Transport costs can represent a significant share of monthly expenses — removing them entirely provides relief precisely to those who can least afford to drive.
What's Next
Porto officials say they will monitor ridership, congestion levels, and air quality data closely over the coming year to evaluate the programme's full impact. If the scheme succeeds in shifting travel habits, it could become a model for other mid-sized European cities facing similar pressures: growing populations, ageing infrastructure, and an urgent need to reduce car dependency.
In a continent where climate commitments increasingly demand a shift away from private vehicles, Porto's free transit experiment may be arriving at exactly the right moment.
