Making Nature-Based Flood Protection Bankable and Attractive for Private Investors

environmentTestedTRL 5

Imagine trying to get a bank loan for a garden that prevents floods, but the bank says it's too risky because they can't see the profit. This project mixes natural greenery with hard engineering to make the results predictable and measurable. It's like adding a guarantee to a green project so investors feel safe putting their money in. By proving it works in several cities, they make these eco-friendly shields a smart business bet.

The business problem

What needed solving

Nature-based flood solutions are often too small, too risky, and too slow to provide returns for private investors. This makes it difficult for cities to fund essential climate resilience without relying solely on public grants.

The solution

What was built

A 'bankability-by-design' assessment tool and 3 climate risk models to quantify the financial benefits of combined green and grey infrastructure.

Business applications

Who can put this to work

Insurance
enterprise
Target: Property and Casualty Insurers

If you are an insurance company dealing with rising flood claims—this project developed 3 climate risk assessment models that reduce uncertainty regarding capital loss. This allows for more accurate pricing of premiums in flood-prone areas.

Civil Engineering
any
Target: Urban Infrastructure Firms

If you are a construction firm dealing with low-budget green mandates—this project developed a bankability-by-design method that combines nature with physical measures. This makes your projects more attractive to lenders and easier to fund.

Finance
mid-size
Target: Green Investment Funds

If you are an investment fund dealing with the high risk of small-scale nature projects—this project developed a way to quantify co-benefits and reduce risk profiles. This turns risky environmental work into a bankable asset.

Frequently asked

Quick answers

How does this affect the cost of implementing flood defenses?

Based on available project data, the project aims to increase investment attractiveness by combining nature-based solutions with physical measures to provide quicker, measurable outcomes.

Can this be scaled to other cities?

Yes, the concept is demonstrated in 3 initial sites (Cesena, Christchurch, Póvoa de Varzim) and tailored for replication in 4 more cities (Ghent, Zhytomyr, Kadikoy) plus 3 additional Demo Cities.

What are the IP or licensing options for the risk models?

Based on available project data, specific licensing terms are not listed, but the project develops 3 climate risk assessment models for reducing uncertainty.

What is the timeline for seeing results?

The project runs from 2025-05-01 to 2030-04-30, suggesting a 5-year development and demonstration cycle.

How does this integrate with existing urban planning?

It uses co-creation processes with local businesses and investors to screen the most adequate solutions for specific sites.

Consortium

Who built it

The consortium is highly diversified with 28 partners across 14 countries, showing strong international scalability. With a 29% industry ratio (8 companies, including 6 SMEs), there is a solid bridge between academic research and commercial application, though the heavy presence of 'Other' organizations (12) suggests a strong focus on municipal and governmental coordination.
