Blue Carbon and marine geoengineering
Blue carbon embodies a promise: that of a renewed alliance between nature and science.
Blue Carbon
The ocean is both a contributor to and a victim of climate change. Its ability to store carbon makes it a valuable ally, but also an extremely sensitive environment. Before turning it into a technological tool, it is essential to understand and preserve it. Blue carbon embodies a promise: that of a renewed alliance between nature and science.
But this promise will only be fulfilled if we act with caution, ethics, and humility, always keeping in mind that the best climate solution remains one that avoids emissions in the first place.
Different approaches to Blue Carbon geoengineering
– Ocean fertilization
– Alkalization
– Artificial upwelling
– Direct CO₂ injection
– Biological control of harmful algal blooms (HABs)
– Permanent carbon sequestration
-
71 %Surface area of the Earth’s ocean
-
25% of CO₂ emitted by human activities absorbed each year by the ocean
-
Before the industrial era the carbon cycle was in equilibrium
-
Potential risks geoengineering for marine biodiversity
-
The solution? reduce emissions at source
The precautionary principle
At the Tara Ocean Foundation, we advocate for the application of the precautionary principle and reflect on the ethical imperatives related to the management of marine ecosystems in the face of anthropogenic climate change.
Key points to remember
Marine geoengineering
- Nor is there scientific consensus that marine geoengineering is risk-free.
- There is no reliable carbon accounting method to assess the sustainability of storage.
- In the absence of certainty, the precautionary principle must apply to all geoengineering activities.
- Meeting the Paris Agreement targets requires a 40% reduction in emissions by 2030: the priority must remain reduction at source, before any offsetting.
