As temperatures across Europe climb to record highs, Paris has repurposed its network of canals into public cooling stations, a move that underscores a strategic divergence in urban heatwave management between continental capitals and British cities. The French capital’s response, while ad hoc, reflects a broader acceptance of climate adaptation measures that London and other UK urban centres have so far resisted, favouring instead a policy of gradual infrastructure upgrades.
The Parisian initiative, announced by the city’s mayor Anne Hidalgo, involves opening up the Canal Saint-Martin and the Bassin de la Villette for extended hours with free access to water misting stations, shaded areas, and mobile hydration units. The programme, expected to run throughout the summer, is designed to provide relief for residents without air conditioning, which remains relatively rare in French homes. This marks a shift from previous years, where urban cooling was largely left to individual initiative, towards a more interventionist municipal approach.
In London, where temperatures are similarly predicted to reach 38°C this week, the response has been markedly different. The city’s public health authorities have issued guidance on staying hydrated and checking on vulnerable neighbours, but have stopped short of implementing comparable public infrastructure measures. The Greater London Authority points to existing green spaces and the Thames as natural coolants, though critics argue these are insufficient for densely populated areas. The UK’s institutional preference for voluntary compliance over mandatory regulation reflects a longstanding tension between individual responsibility and state intervention.
The strategic difference is rooted in differing conceptions of urban resilience. Paris, under Hidalgo’s leadership, has embraced the concept of the “15-minute city”, which prioritises local access to services and green spaces. This philosophy extends to heatwave planning, which is seen as an extension of broader climate adaptation rather than a crisis response. British urban planning, by contrast, has historically favoured market-led development, with cooling provisions often built into private developments rather than public amenities. This has led to a patchwork of provision, where wealthier neighbourhoods have tree-lined streets and modern ventilation, while poorer areas suffer disproportionately.
Data from the UK Health Security Agency indicates that heat-related mortality in England has increased by an average of 2,000 deaths per year over the past decade, with the highest rates in urban areas. Yet the government’s National Adaptation Programme, published last year, has been criticised for its lack of specific urban cooling targets. The Paris example, while not a panacea, raises questions about whether British cities are underinvesting in public health infrastructure.
There are signs of change. Manchester has piloted “cool corridors” connecting green spaces, and Birmingham has committed to increasing tree canopy cover. But these initiatives remain localised and underfunded. The Parisian canal scheme, on the other hand, has been integrated into the city’s climate plan since 2018, with dedicated budget and staffing. Its success may be measured not just by reduced heat-related illness, but by the signal it sends about institutional priorities.
The reluctance to adopt Paris-style measures in British cities is not entirely irrational. Canals and rivers present drowning and pollution risks, requiring additional safety measures. Moreover, British infrastructure is built to British weather: a summer that peaks at 40°C is still exceptional, whereas Paris has historically seen higher temperatures. Nevertheless, as heatwaves become more frequent and intense, the argument for pre-emptive action is growing. The Paris model offers a template, but it also exposes the cost of inaction. For now, Londoners may find solace in the city’s many water fountains: a modest measure that reflects the limits of its current ambition.
