Mitigating climate risk

Highlight Stories

Climate Risk

Climate change poses one of the most pervasive risks to our planet and our prosperity. Its effects are already evident and shaking up our risk landscape: warmer average temperatures, rising sea levels, longer and more frequent heatwaves, heavy storms and rainfall, more floods, wildfires and weather extremes.

Swiss Re identified the threat of climate change as far back as 1979 and has been analysing its effects on society and the insurance industry ever since. As the threat has become more and more apparent, we've worked with our clients, partners and governments to take the actions to reduce the causes of climate risk and insure what cannot be mitigated.

What we focus on

We focus on three primary areas of climate change risk that we feel are most important for society and where we can provide solutions to the underlying risks:

Natural catastrophes and the protection gap

Most natural catastrophe losses, including those caused by climate change, are not covered by insurance. This means that millions of households and businesses face a large and widening protection gap. With its re/insurance solutions, Swiss Re protects communities and businesses against the financial fallout from natural catastrophes, helping them recover quickly after a disaster and adapt to climate change.

Transition to a net-zero economy and the role of renewables

Notwithstanding the negative impact on our communities, our health and our natural world, climate change could also become a permanent drag on our economy. Without climate risk management and drastically reducing carbon emissions with a goal of net zero, the global economy will be significantly smaller by mid-century due to income and productivity losses.

Swiss Re offers innovative solutions for the journey to a net – zero economy by minimizing the risks associated with renewable energy and infrastructure projects while helping to drive continued growth and investment in the renewable energy sector. Our risk knowledge and expertise on renewables includes wind, solar, hydro, biomass, geothermal and battery storage as well as grid enhancement projects, making Swiss Re the partner of choice.

Progress through public-private partnerships

The most urgent question we need to address is how best to tackle the source of the climate change problem by drastically reducing carbon emissions and how to avert the most damaging consequences by adapting to impacts that are already unavoidable. No single industry or region can do this alone. Meeting a challenge of such magnitude can only be achieved in partnership between the public and private sectors.

Natural catastrophes in 2025

2025 again highlighted the world’s deepening exposure to natural catastrophes.
Insured losses reached USD 107 billion, driven by record-breaking wildfires in Los Angeles, another highly costly season of severe convective storms across the US, the catastrophic impacts of Hurricane Melissa in Jamaica, where insured losses are estimated up to USD 2.5bn, and widespread flooding across Southeast Asia.

Even without major US hurricane landfalls, losses remained structurally high. The year’s events reinforce a clear message: resilience and adaptation must accelerate if societies are to keep pace with escalating risk.
