Severe weather is becoming more common, costly, and disruptive for cities and businesses. Nearly three-quarters of organizations have experienced losses or work disruptions from weather devastation, according to a 2025 global survey by insurer Marsh. This creates issues including higher insurance costs and work stoppages, as well as water shortages that shutter factories.
But a growing number of cities are increasing their climate resilience and therefore their marketability to businesses, according to a report from Oliver Wyman Forum. Ranking the business attractiveness of 1,500 cities globally, the report shows that central and northern European destinations like Bern, Oslo, and Gothenburg are currently top ranked in climate resilience, while other cities are poised to rise.
How are cities managing climate risk?
Far-flung cities from Paris and Miami to Singapore and Sierra Leone's Freetown are using targeted investments to reduce risk, and secure their positions as climate-resilient hubs for talent, trade, and business.
The following four actions have been especially helpful to them:
Safeguarding cities from climate devastation
A growing number of cities are investing in infrastructure that protects against the devastation of floods or extreme heat.
Singapore’s climate resilience plans, for example, include sea walls for coastal and flood defence and mandatory water recycling requirements for new projects in water-intensive industries to help prevent scarcity.
Other cities, like Sao Paulo, Brazil, plan to insulate houses with green areas to help prevent deaths, harvest rainwater and protect against water runoff and flash floods. And in South Africa, Johannesburg is planning for high flood-risk areas to be free of houses, offices, and critical infrastructure by 2050.
Bolstering supply chains against climate change
The world’s supply chains are also exposed to climate risk because many manufacturing hubs are in flood-prone or water-scarce areas. But 45% of CEOs are planning to reconfigure their company's supply chains, according to 2026 research from Oliver Wyman Forum. Cities that position themselves as safe bets as logistics hubs could see higher business investment as a result.
The Port of Rotterdam, for example, is Europe’s largest seaport and accommodates roughly 30% of the EU’s container traffic. In preparation for rising sea levels and increased floods, the city’s adaptation strategy proposes raising quays and roads and relocating business-critical facilities like electricity and telecoms to safer, higher-ground areas.
Chinese cities have an opportunity to lead in Asia, where more than 40 of its top 100 manufacturing cities are at high risk of flooding, according to Oliver Wyman Forum data. Sustainability investments in places like Shenzhen, which has a coastal defence system, may persuade manufacturers to stay in China rather than diversify to lower-cost countries.
Investments in renewables technology, such as water recycling systems, also protect against the water scarcity that will challenge other less developed cities.
Those cities that are considered a part of companies’ “China plus one” supply chain strategies – in which companies diversify operations to an additional location outside of China – should also be proactive in protecting their attractiveness in this respect.
Chihuahua, Mexico, for example, has benefitted from supply chain shifts but is vulnerable to water shortages. While the city’s use of treated wastewater to irrigate green spaces has helped ease the pressure, it should invest more in resiliency infrastructure.
Investing in liveability and talent attraction
Climate resilience and liveability are key to attracting and retaining the world’s best employees – from architects to AI engineers. Talent often migrates from cities affected by excess heat and humidity, frequent floods, or water shortages to areas with milder climates, more resilient infrastructure, and easy access to natural surroundings and activities.
Many of the most climate-resilient cities highlighted by the report excel at this by proactively investing in liveability. Sweden’s Gothenburg, for example, blends liveability, climate resilience and job attraction. The city offers nearly 3,000 square feet of green space per resident and benefits from a national initiative to decarbonize the industrial sector and create new jobs.
Cities in warmer climates can adopt similar methods. Riyadh in Saudi Arabia, for example, uses smart systems and reflective materials to ensure buildings are sufficiently cooled. Its urban planners also are creating more canopies and small green spaces to improve walkability.
Building public-private partnerships
Cities and businesses can collaborate to manage the rising costs of devastation.
Singapore launched a public-private partnership in April 2026 to help strengthen businesses’ climate resilience in areas like green procurement and sustainable financing, for example. The government also issued supervisory guidelines for financial institutions to manage their own and their wider portfolios’ climate risk by adapting their business, governance, and risk management models.
Building a defense against climate risk
Businesses should consider the cost of inaction, as well as proactively assessing climate risk to safeguard their people, infrastructure, and operations – particularly amid supply chain and macroeconomic shifts. Part of this assessment should involve analyzing which cities are best defended against climate risks.
And for cities themselves, investing in clean technologies, jobs, and infrastructure, and creating forward-looking plans, can help to position these places as a wise choice for business investment – particularly as severe weather events happen more frequently.
