About Us
Learn more about the history and goals of the Global Mangrove Trust
Global Mangrove Trust is a Singapore-based non-profit organization dedicated to leading the preservation and regeneration of mangroves worldwide. Our diverse team—comprising innovators, educators, and environmentalists—operates under the guidance of an esteemed advisory board of forward-thinking individuals and organizations. Driven by a blend of urgency and hope, our mission is to develop self-financing regenerative easements to protect all mangrove ecosystems globally. These critical habitats are not only essential for combating climate change but also provide significant socio-economic benefits to local communities. By collaborating with local impact partners and leading teams across the globe, we ensure that families and businesses are actively involved in community-based mangrove forestry. Aligned with twelve of the UN Sustainable Development Goals, we strive to create a sustainable and equitable world where mangroves thrive and communities prosper.
Our Story
It was beneath the dense canopy of the Thor Heyerdahl Climate Park in Myanmar where our co-founders, Ryan and Simon, found their calling. Initially there to draft a narrative on environmental strategies for Harvard Business School, they stumbled upon something far more elemental. Wandering between the sprawling mangroves, Simon paused—a moment of stillness amidst the lush, muddy labyrinth. There, stripped of the day’s high-tech discussions and complex climate debates, they realized that true environmental impact extends beyond advanced tools like drones and carbon sequestration. It resides in the living, breathing earth itself. At Global Mangrove Trust, we embrace this profound truth: the real power lies in nature’s intricate systems and vibrant life.
Our Values
At the core of our identity and actions lie our values—principles that guide us in making decisions, shaping interactions, and fostering a culture of inclusivity and growth. Here are the five values we stand by:
Our Promise
At GMT, we believe in the power of nature. It was a serene moment among the mangroves that opened our eyes to the incredible value hidden just beneath our feet. We are committed to making climate action straightforward, transparent, and impactful.
Utilizing peer-to-peer funding, we plant mangroves to achieve three critical goals: sequestering carbon, supporting local communities, and enhancing biodiversity. This approach not only tackles environmental challenges but also strengthens the very fabric of the ecosystems we help to restore. By connecting donors directly with reforestation efforts, we ensure that every contribution has a direct and measurable impact on the planet.
