Climate: adaptation finally proves its profitability, up to €13 for every €1 invested.

A global study demonstrates the profitability of climate adaptation: up to €13 in benefits for every €1 invested

For several years, it has been said that every euro invested in climate change adaptation yields between 8 and 13 euros in benefits, without really knowing whether this is wishful thinking or a concrete, measured economic reality. Tangible, quantified, and scientific evidence was lacking to prove that this ratio is not just a slogan, but indeed a measurable and reproducible economic outcome.
This has now been accomplished.

A study published in 2025 by the World Resources Institute (WRI) finally provides tangible and quantified evidence: adaptation is not a cost, but a highly profitable investment.

Based on more than 320 projects conducted across 12 countries, this analysis demonstrates that, on average, 1 dollar invested generates 10.50 dollars in benefits, with a return on investment (ROI) of around 27%.

Remarkably, a significant portion of these benefits occurs even in the absence of an extreme climate event. In other words, adapting means investing in economic performance, competitiveness, and long-term stability.

Three benefits (“dividends”) that change the perception of adaptation

The Triple Dividend of Resilience (TDR) analytical framework, developed by the WRI, shows that the benefits of adaptation have been widely underestimated until now.

Too often, economic analyses only account for avoided losses, such as infrastructure protected against flooding. However, the other two economic, social, and environmental benefits often represent double the initial gains.

 The WRI analytical framework relies on three levels of dividends:

· Dividend 1: avoided losses – reduction of property damage, crop losses, and business interruptions.
· Dividend 2: induced development – increased productivity, job creation, land value appreciation, maintenance savings, and heightened investor appeal.
· Dividend 3: social and environmental benefits – improved health, poverty reduction, carbon sequestration, biodiversity conservation, and collective well-being.

On average, more than half of the benefits of the evaluated projects do not depend on the occurrence of a climate hazard. This is a major finding: adaptation becomes a strategy for sustainable performance, not a defensive expense.

Concrete and measurable returns on investment

The WRI relies on real-world projects funded by the World Bank, the Asian Development Bank, and the African Development Bank. These projects span various sectors (agriculture, healthcare, energy, urban infrastructure) and demonstrate that economic benefits far outweigh the initial costs.

Adaptation and mitigation: the winning combination

Nearly half of the analyzed projects offer co-benefits in emissions reduction, paving the way for hybrid financing mechanisms: adaptation funding, carbon financing, and public-private partnerships.

The WRI shows that projects combining adaptation and mitigation are the most attractive to investors: they strengthen operational stability while enhancing the non-financial profile. The so-called “second dividend” economic benefits — increased productivity, jobs created, purchasing power — provide a solid foundation for private investment. In other words, adaptation ceases to be an environmental expense: it becomes a driver of competitiveness and growth.

Adaptation: a strategic and measurable investment

The WRI study finally substantiates, with empirical data, the ROI ratios highlighted by numerous sources (McKinsey & Co., OECD, Swiss Re Institute, WEF, US Chamber of Commerce, Government of Canada).

 The results across 320 adaptation measures are compelling:

· Average ROI: 27%
· Benefit: $10.5 per dollar invested
· Positive effects observed even without a disaster
· Alignment with SDGs and ESG criteria

The WRI study assesses these benefits across four dimensions:

· physical damage,
· financing,
· productivity,
· and overall ROI.

 Adaptation measures lead to a reduction in direct losses and downtime, improved insurability, lower financing costs, as well as performance gains related to operational continuity and improved working conditions.

In other words, not adapting costs far more than taking action. Adaptation is becoming a pillar of economic, social, and environmental performance. American companies and communities have already embraced this: according to the Tailwind report (2024), adaptation investments were 23 times higher in the United States than in Europe. Organizations that invest in their resilience today secure their profitability, reduce their cost of capital, and strengthen their long-term attractiveness.

Frequently Asked Questions

How much does €1 invested in climate change adaptation yield?

The study published in 2025 by the World Resources Institute, based on more than 320 projects conducted across 12 countries, measures an average of $10.50 in benefits for every $1 invested, with a return on investment of approximately 27%. Other sources, such as the Government of Canada and the Canadian Climate Institute, report ratios of $13 to $15 for every $1 spent.

Do the benefits of adaptation only exist in the event of a disaster?

No. According to the WRI, more than half of the benefits of the evaluated projects do not depend on the occurrence of a climate hazard. The triple dividend of resilience framework accounts for avoided losses, induced development (productivity, jobs, land appreciation, maintenance savings), and social and environmental benefits.

In which sectors have these investments been evaluated?

The studied projects, funded by the World Bank, the Asian Development Bank, and the African Development Bank, cover agriculture, healthcare, energy, and urban infrastructure. These averages do not replace site-specific quantification for each company: the return on a measure depends on the site, the hazard, and the cost of inaction.

How do you measure the ROI of an adaptation measure in your company?

An adaptation measure is profitable when the present value of avoided losses exceeds its implementation cost. The WRI evaluates benefits across four dimensions: physical damage, financing, productivity, and overall ROI. Horizon applies this logic site by site: it quantifies in euros the climate impact on each of your sites or your portfolio, then identifies the most profitable adaptation measures from a catalog of 62 quantified measures.

Measure the return on adaptation across your own sites? Horizon quantifies the cost of inaction and the return on adaptation measures; Protect alerts you up to 5 days in advance when a critical threshold for your activity, sites, or teams is about to be exceeded. Book a meeting with our experts.
