Nature-Based Coastal Defense and Carbon Capture Solutions for Shoreline Management

environmentTestedTRL 4

Imagine the coast as a giant sponge that protects the land from storms and sucks up carbon from the air. Right now, these sponges are worn out and broken. This work figures out how to let nature fix itself so we have a cheaper, natural wall against rising seas.

The business problem

What needed solving

Coastal areas are losing their natural ability to protect land and store carbon due to pollution and development. Current man-made defenses are often expensive and fail to support biodiversity.

The solution

What was built

The project is developing scenario-modeling tools and a network of 10 demonstration sites to test rewilding versus active restoration.

Who can put this to work

Civil Engineering
enterprise
Target: Coastal infrastructure developers

If you are a coastal infrastructure developer dealing with expensive concrete sea walls that erode—this project developed nature-based solutions that use intertidal sediments to protect the shoreline. This reduces the need for heavy construction while supporting biodiversity.

Environmental Services
mid-size
Target: Carbon credit developers

If you are a carbon credit developer dealing with a lack of verified blue carbon sites—this project developed methods to estimate carbon sequestration in 10,000 km2 of intertidal areas. This provides the data needed to quantify carbon capture for offsets.

Government & Urban Planning
any
Target: Municipal coastal management agencies

If you are a municipal agency dealing with conflicting land-use pressures and climate risks—this project developed scenario-modeling tools to compare 'do nothing' versus rewilding options. This helps in making data-driven decisions for shoreline resilience.

Frequently asked

Quick answers

What is the cost or price of implementing these solutions?

Based on available project data, specific pricing is not provided, but the project aims to ensure a high ecological and societal co-benefit to low-cost ratio.

Can these methods be scaled to an industrial level?

The project tests these methods across 10 demonstration sites and aims to upscale trajectories from local to the European level, covering over 10,000 km2 of intertidal areas.

What are the IP and licensing terms for the tools developed?

Based on available project data, there is no specific mention of patents or licensing agreements in the provided text.

How does this align with current environmental regulations?

The project focuses on carbon neutrality and biodiversity support, aligning with European priorities for climate adaptation and nature-based solutions.

What is the timeline for deploying these results?

The project period runs from 2023-10-01 to 2028-09-30, suggesting that final validated tools will be available toward 2028.

Consortium

Who built it

The consortium is heavily academic, with 18 universities and 4 research institutes, indicating a strong focus on data validation and scientific rigor. However, the inclusion of 2 industry partners and 1 SME suggests a bridge to commercial application. With 25 partners across 14 countries, the project has significant geographic reach, which is critical for validating nature-based solutions across diverse coastal climates.
