Porto Readies Free Metropolitan-Area Public Transport for Residents, With a July 1 Start Riding on the Court of Auditors
Free travel across the Porto metropolitan area for Cartão Porto holders is set to begin on 1 July — or whenever the Court of Auditors signs off, with a January 2027 backstop. The city has budgeted up to €10.25 million for 2026.
Free public transport for Porto residents is on the verge of becoming reality. Under a contract signed with Transportes Metropolitanos do Porto (TMP, the Porto Metropolitan Transport authority), the measure is scheduled to take effect on 1 July 2026 — or on the date the Court of Auditors (Tribunal de Contas) grants its visa, whichever comes later.
That caveat matters: the launch hinges on the audit court signing off, and if the visa slips, a firm fallback start date of 1 January 2027 kicks in.
Who benefits, and where
The scheme covers residents of the city of Porto who hold the Cartão Porto (Porto Card). It extends free travel across the entire Área Metropolitana do Porto (Porto Metropolitan Area), with a territorial scope equivalent to the metropolitan Andante pass. Today, Porto Card holders receive just 22 free trips a year; the new measure replaces that allowance with unlimited travel on the metropolitan network.
What it costs
- The city has budgeted a maximum of €10.25 million for 2026, rising to €18.7 million in 2027 and €1.8 million in 2028.
- Mayor Pedro Duarte, who championed the policy as a campaign pledge, has called it "innovative and pioneering" and a paradigm shift in urban mobility.
- The Municipal Assembly approved the contract with opposition from Chega and abstentions from the CDU and the "Filipe Araújo: Fazer à Porto" municipal group.
Part of a wider trend
Porto's move follows a broader Portuguese push to lower the cost of getting around, from the national monthly rail passes to metropolitan fare caps in Lisbon. Supporters argue free transit eases congestion and pollution and supports lower-income households; critics question the long-term cost and whether the money is better spent expanding service frequency and coverage.
What this means for residents
- Eligibility check: The benefit is tied to the Cartão Porto, so residents will need to hold or apply for the card to travel free — non-residents and visitors are not covered.
- Timing: Do not cancel a metro pass just yet; the start depends on the Court of Auditors' visa, with January 2027 as the guaranteed backstop.
- Metropolitan reach: Because coverage matches the metropolitan Andante zone, the perk extends well beyond the city core to surrounding municipalities.
If the audit court clears the contract on schedule, Porto will become one of Portugal's largest cities to offer residents genuinely free public transport — a test case other municipalities will be watching closely.
