As the world races toward net zero, the terms blue economy and blue carbon are gaining serious attention—especially in regions like the UAE where coastlines and marine ecosystems play a major environmental and economic role. But what exactly is blue carbon, and why is it such a key contributor in the fight against climate change?
Let’s dive into what makes blue carbon so powerful and why it’s becoming a cornerstone of the UAE’s climate strategy.
What Is Blue Carbon?
Blue carbon refers to the carbon dioxide (CO2) captured and stored by coastal and marine ecosystems. Unlike terrestrial forests, which we often associate with carbon capture, blue carbon focuses on mangroves, seagrasses, and salt marshes—ecosystems that are incredibly efficient at locking away carbon.
These natural environments absorb CO₂ from the atmosphere through photosynthesis and store it in both their vegetation and the substrate below. What makes them unique is their ability to sequester carbon faster and for longer periods than most land-based forests.
How Coastal Ecosystems Power Carbon Sequestration
Let’s break down the role of key ecosystems in blue carbon capture:
- Mangroves: Found along the UAE’s coastline, mangroves are champions at storing carbon and each tree can store up to 12.3 Kg per year. They not only absorb CO₂ into their biomass (leaves, branches and roots), but also also perform a coarse water filtration role, which traps sediment and organic material within their complex root systems, effectively locking carbon in the ground for centuries and creating what we call blue carbon. The mangroves in the UAE typically live for 25-30 years on average, and upon their death, will release some of the CO₂ sequestered in their biomass back into the atmosphere.
- Seagrass Meadows: These underwater plants capture carbon and act as vital nurseries for marine life. Though they cover only a fraction of the ocean floor, they are estimated to sequester up to 10% of the ocean’s total carbon each year. Like all plants, seagrass photosynthesises CO₂ from its environment an transforms it into organic carbon that it stores in its biomass, however, this is a small part of its carbon sequestration superpower. Seagrass also slows down water movement and stabilises the benthos with its complex root and rhizome system. This combination performs a fine filtration of carbon rich sediments in the water and sequesters them under the seafloor. The anoxic conditions in the benthic sediment layers mean that decomposition is significantly reduced, and this blue carbon is stored for millennia. It is estimated that seagrass can sequester carbon up to 35 times faster than tropical rainforests!
- Salt Marshes: These wetlands act as buffers between land and sea and are effective at both capturing carbon and reducing coastal erosion.
Together, these ecosystems provide natural carbon sequestration, helping to reduce greenhouse gases while also protecting biodiversity, improving water quality, and safeguarding against rising sea levels.
Why Blue Carbon Matters for the UAE
The United Arab Emirates has long recognised the value of its marine ecosystems—not just for heritage and biodiversity, but as a strategic asset in the path to net zero emissions by 2050. As a desert nation, the opportunity to sequester carbon through forestation is limited, however the significant coastline in the UAE provides opportunities for nature based solutions to dramatically increase the available geographic area for carbon capture.
🇦🇪 Key UAE Initiatives Supporting Blue Carbon:
- The UAE Net Zero by 2050 Strategic Initiative includes nature-based solutions as a key focus area.
- Massive investments have been made in mangrove restoration, with the government committing to planting 100 million mangroves by 2030.
- Dubai and Abu Dhabi are home to several blue carbon pilot projects focused on monitoring, preserving, and expanding carbon-rich ecosystems.
These efforts position the UAE as a regional leader in leveraging blue carbon Dubai projects to fight climate change.
The Economic & Environmental Case for Blue Carbon
Beyond climate goals, blue carbon has major investment potential. With the rise of carbon markets, companies can now offset their emissions by investing in verified blue carbon projects. This supports ecosystem restoration while helping businesses meet ESG targets and carbon neutrality goals.
As a nature-based solution, blue carbon offers a cost-effective, scalable, and sustainable approach to carbon sequestration—and it’s available right here in the UAE.
