CIVITAS Inspiration on Public Transport: Preparedness for future shocks and disruptions with climate-resilient systems

This brief focuses on how European cities can strengthen preparedness for future shocks and disruptions by building climate-resilient public transport systems. It starts from the premise that public transport is the backbone of urban mobility, yet climate change is increasing the frequency and intensity of extreme weather events that can disrupt networks and endanger passengers. It highlights a range of climate-related shocks that already affect cities, including pluvial, fluvial and coastal flooding, as well as heatwaves. These events can cause infrastructure failures that interrupt service and create hazardous conditions, with direct implications for passenger safety and health.

A recurring concern is heat. More urban residents are regularly exposed to heatwaves, worsened by climate change and the urban heat island effect. It stresses that these conditions pose serious health risks, especially for vulnerable groups such as older people, who are also more likely to depend on public transport. In response, it points to the increasing importance of heat-resilient measures such as improved shading at bus and tram stops and cooling of underground metro stations. It also notes that climate conditions can influence travel behaviour and may increase demand for public transport during extreme heat, when active modes become impractical or unsafe.

The brief defines resilience as more than robust infrastructure: a resilient network should maintain or rapidly restore essential mobility during a crisis, while also anticipating future risks and adapting assets to evolving climate conditions. It links this directly to equity and social justice, arguing that when climate-induced disruptions impact public transport they can isolate low-income individuals, older people, people with disabilities and other marginalised communities, deepening existing inequalities. It also highlights public transport’s role in crisis response and recovery, enabling evacuation and access to shelter, food and medical care, and supporting faster post-disaster recovery, especially for residents without private vehicles.

The key challenges cities face when integrating resilience into public transport planning are several, namely: uncertainty and lack of urban‑scale climate data for transport decision‑making; vulnerability of long‑lived, path‑dependent infrastructure and outdated design standards; fragmented governance across actors and levels; limited resilience funding that must be integrated with sustainability, accessibility and comfort priorities; and the interconnected nature of urban systems, where disruptions can cascade across services and across regions.

Some best practices are presented on how EU cities are tackling these issues, including Mannheim’s heat adaptation actions (e.g., green tracks and green stops and flexible on‑demand/shared services), Paris’ Heatwave Resilience Plan for the 2024 Olympic and Paralympic Games, Copenhagen’s metro flood‑adaptation strategy embedded in planning/design, and Vienna’s “greened bus stops” (shown to be 1–1.5°C cooler than conventional stops).

Key Recommendations

The brief draws several recommendations for strengthening climate resilience in public transport, based on research lessons and city examples:

1. Develop and adopt resilience indicators (KPIs). Establish standardised indicators to assess climate risks, prioritise investment and track progress over time. The indicators should cover both infrastructure vulnerability and social resilience, so adaptation benefits are equitable and protect vulnerable groups. It proposes key dimensions including vulnerability assessment, flexibility/continuity, equity/accessibility, operational reliability, and preparedness/governance.
2. Future‑proof new infrastructure from the start. The recommendation is to plan long‑lived assets (metros, railways, major corridors) with current and future climate risks in mind, integrating projections for hazards such as sea level rise, extreme heat and flooding into siting, design and materials. Early integration reduces long‑term costs and improves operational continuity. Copenhagen’s metro strategy of embedding adaptation into the planning and “dimensioning phases” and updating designs as climate projections change is presented as a strong illustration of this principle.
3. Invest in high‑quality, multi‑purpose infrastructure and maintenance. Resilient infrastructure must be well‑designed, well‑built and well‑maintained, supported by predictable funding across levels of government. Cost‑effectiveness improves when investments serve multiple objectives. Measures like Vienna’s “green islands” on bus shelters (microclimate, comfort, biodiversity) and Mannheim’s green tracks/stops show how adaptation can deliver broader co‑benefits.
4. Strengthen multi‑level governance and coordination. The brief calls for governance frameworks with clear responsibilities and action timelines, and close cooperation between cities, transport operators, emergency services, national governments and EU institutions to ensure coordinated response during climate emergencies. Paris’ Heatwave Resilience Plan is presented as a multi‑actor strategy developed in partnership with the Paris 2024 organising committee and stakeholders.
5. Leverage digital tools and satellite data. Use technologies such as satellite monitoring, remote sensing and predictive analytics to support proactive infrastructure management, climate risk assessment and real‑time crisis response.
6. Promote knowledge‑sharing and peer learning. The brief emphasises that some cities have decades of experience while others are just beginning, and recommends EU‑wide initiatives and city networks to spread tested, scalable solutions so cities do not “reinvent the wheel” and public investment has greater impact.
