Seaweed vs. Trees

We have long celebrated trees as nature’s main carbon-capturing resource. They take in carbon dioxide through photosynthesis and in turn, give us oxygen, shade and a home for wildlife. Forests have been the most evocative symbol of environmental protection with sustainability and planting trees usually being considered the gold standard in offsetting carbon emissions. But with climate crisis worsening, many have begun to ask whether trees can keep pace with the urgency of out carbon sequestration needs.

Why Seaweed Could Outperform Trees


Faster Growth:

Some species of seaweed, like kelp, grow as fast as 60 cm in a single day, making them among the fastest-growing organisms in the world. Trees take decades to reach their full carbon-absorbing potential.


Carbon Absorption in Water:

While trees take up CO₂ from the atmosphere, seaweed absorbs it from the surrounding water, thus helping to reduce ocean acidification, an increasingly serious peril to marine life.

No Land Required:

Planting trees requires wide areas and often competes for space against agriculture or the expansion of a human settlement. 

Seaweed thrives in nutrient-rich waters, making this solution space-efficient for capturing carbon.

Permanent Carbon Storage:

When seaweed is harvested and converted into biochar, the carbon can be sequestered for centuries, unlike that from trees, which can release their carbon when they decompose or burn.



The Perfect Partnership: Trees and Seaweed


While seaweed offers incredible potential, it’s not about replacing trees; rather, it’s about adding seaweed to our toolkit for fighting climate change. Trees cannot be replaced in their role of supporting biodiversity on land, preventing soil erosion, and creating shade for urban cooling. Meanwhile, seaweed contributes to marine biodiversity, helps combat rising CO₂ levels in the ocean, and supports coastal communities. Together, these nature-based solutions can work in harmony to capture carbon and protect our planet.
