Marine dredging, the process of removing sediment from the ocean floor, is a common practice that causes significant carbon dioxide (CO2) emissions, contributing to the global climate crisis.

In some cases, marine dredging may be necessary, for example, for maintaining and deepening navigation channels and harbours, or to protect shorelines from erosion caused by waves, currents, and storms.

In a time when sustainability news is often rather pessimistic, we think it’s also important to shed light on the positive developments and share the great projects that are happening. Preserving nature and enhancing sustainability is critical and urgent. There are already hundreds of projects helping the planet and helping society move in the right direction. 

There is still so much to do, but let’s see what’s already happening out there.

We live in a time when organisations are larger than ever before, and their impact, both positive and negative, can be greater than ever.

Fortunately, in recent years, more and more companies are moving sustainability to the top of their agendas and seeking methods to reduce their environmental footprints.

In the past few years, everything related to sustainability has been tagged as “green”. Green energy, green growth, green products… this is all great. But what about Blue?

Back in the 19th century, the North Sea was an oyster paradise. These bivalves were not only a culinary delight but also played a vital role in our coastal ecosystems. However, today, their presence in the wild is very rare. What happened to oyster reefs, and why are flat oysters nearly extinct in nature?

The Earth’s climate is rapidly changing, and the consequences are becoming increasingly evident. Rising temperatures, extreme weather events, and melting ice caps are just a few of the alarming signs. Addressing Climate Change is a complex global challenge. However, there’s a powerful ally that is often overlooked: the ocean.

We often talk about the incredible capabilities of oysters to filter water. They are highly efficient filter feeders, selectively extracting the most nutritious particles from the water. But how do they do that? And why is it relevant? 

Oyster restoration projects play a vital role in preserving marine ecosystems and mitigating the effects of climate change. These projects have taken place in different parts of the world over the past years, both offshore and near the coasts.

In the vast blue expanse of our oceans, a hidden threat lurks beneath the surface: eutrophication. This complex term describes a concerning phenomenon driven by human activities, impacting marine ecosystems in ways we can no longer afford to ignore. 

Eutrophication occurs when excess nutrients, primarily nitrogen and phosphorus derived from human activities, enter water systems leading to excessive algal growth that disrupt the balance of marine ecosystems.
