A new study that analysed the severe heatwaves that occurred over the past quarter century has revealed that these could not have happened without human-caused climate change.
The new research conducted by Ortec Finance reveals that nearly two-thirds of respondents allocate 4% of their investment portfolio to sustainable investments, such as green bonds, social bonds and impact investing.
Ortec Finance’s poll of global investors responsible for $10.48tn of assets found that more than 90% expect climate risk and impact investing to become more important, with 29% thinking it will become much more important.
The study found that insurance investment managers and investment managers need more support on understanding the impact of different climate scenarios on their investments.
Around one in four described their organisation’s current understanding of climate impacts as average, while 76% considered their knowledge of different scenarios to be good.
Nearly a fifth of the surveyed executives said that only 3% of their investment portfolio was dedicated to sustainable investments.
Ortec Finance managing director UK and head of insurance and investment Hamish Bailey said the findings showed “a growing need for stronger support and a more rigorous, forward-looking approach to managing climate-related risks and opportunities, now and into the future”.
“A significant number of organizations in the study acknowledge they need to do more, with many admitting their understanding of the potential impact of different climate scenarios on their portfolios could improve.”
Ortec Finance commissioned independent research company Pureprofile to interview 100 senior executives working in insurance asset management or in investment management firms supporting insurers in May 2025. Survey respondents are located in the UK, France, Germany, Switzerland, Hong Kong, Malaysia, Singapore and Norway.
