Allianz models a 40% real estate correction under aggressive climate policy
The urgency behind these investments is sharpened by what happens if they are delayed. Allianz board member Günther Thallinger wrote on LinkedIn in March 2025 that the world is «fast approaching temperature levels — 1.5°C, 2°C, 3°C — where insurers will no longer be able to offer coverage for many of these risks. The math breaks down; the premiums required exceed what people or companies can pay. This is already happening. Entire regions are becoming uninsurable.»
Allianz’s 2025 report, Climate Risk and Corporate Valuations, modeled the financial impact of climate scenarios across 10 sectors in the US and Europe using discounted cash flow models and interest coverage ratios. Under the Net Zero 2050 scenario — aggressive climate policy with ambitious carbon-reduction targets — European real estate faces a 40% correction in valuations. US healthcare and consumer discretionary sectors would each drop by roughly 16%, while energy and basic resources face smaller declines of 6% to 7%, partly reflecting adaptation through renewables.
Lead Investment Strategist and co-author Jordi Basco Carrera warns that the alternative is worse: «A delayed transition is not a soft landing. It’s storing up energy for a much more violent adjustment later. The sectors that look like they’re benefiting in the short term are accumulating hidden risks.» For CFOs, he argues, traditional insurance cannot protect against the systematic repricing of entire portfolios as carbon-intensive business models become economically unviable.
Allianz’s methodology drew on data from the Network for Greening the Financial System (NGFS), a voluntary international group of central banks launched in 2017. The report also introduced the concept of Climate Elasticity of Demand, measuring how global warming reshapes demand for goods and services — a tool Basco Carrera says gives CFOs the granularity needed for capital allocation decisions.
WRI documents 27% average returns across 320 resilience projects
The investment case is further supported by research from the World Resources Institute (WRI), a Washington, DC-based global research nonprofit. Its analysis of 320 adaptation and resilience projects across agriculture, water, health, and infrastructure found that the investments collectively cost over $133 billion and were expected to generate $1.4 trillion in benefits over 10 years, with individual investments generating an average return of 27%.
WRI senior fellow Carter Brandon believes even these figures are conservative: «We found that only 8% of investment appraisals estimated the full monetized values of these dividends, suggesting that the $1.4 trillion and the average rate of return are likely substantial underestimates.»
