By quantifying the carbon sequestration potential of seaweed farms, the Global Seaweed Project demonstrates the feasibility of creating a new blue carbon market that can support both climate mitigation and the development of a sustainable Blue Economy. Additionally, the project highlights the significant social impact of seaweed farming, with over 99% of participating farmers, most of whom are women, coming from coastal communities in developing countries. This underscores seaweed farming&#8217;s potential to promote gender equity, improve food security, and strengthen local resilience to climate change.<\/p>\n\n\n\n<p>In 2021, the Global Seaweed Project was awarded the prestigious Keeling Curve Award that recognizes outstanding initiatives to reduce greenhouse gas emissions.

We believe in the power of collaboration to achieve this goal. Oceans 2050 focuses on strategies that bridge the gap between people and the planet by empowering ocean changemakers, scaling innovative technologies, enabling transformational initiatives, and developing public tools to accelerate the restoration of abundant oceans by creating a connected experience right at our fingertips.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>About the Global Seaweed Project<\/strong><\/h3>\n\n\n\n<p>Launched in September 2020, The Global Seaweed Carbon Project aims to harness the power of seaweed farming to mitigate climate change and restore ocean health. By quantifying the carbon sequestration of macroalgae (seaweed) beneath seaweed farms, we are creating a pathway to a new blue carbon market that can drive sustainable growth. This project enhances understanding of seaweed farming\u2019s role in capturing carbon, attracts investment, and generates additional revenue streams for farmers while restoring marine ecosystems. Our ultimate goal is to create the conditions needed to scale up seaweed farming, potentially removing gigatons of atmospheric CO\u2082 and regenerating our oceans.
