Our Impact

After achieving the milestone of planting one million SeaTrees on Earth Day 2021, SeaTrees achieved our next major goal of planting two million SeaTrees across our ten projects. We would like to thank all of our donors and partners who helped make this happen. Our next goal is to support 100 SeaTrees projects by the end of this decade (2030).


2 Million+ SeaTrees breaks down as follows:

- 1.8 million+ mangrove trees planted at our project sites in Mida Creek, Kenya, Marereni, Kenya, Biak Island, Indonesia, and Laguna San Ignacio, Mexico.

- 340,139 sq-ft of kelp restoration at our project sites in Palos Verdes, CA, Tankers Reef, Monterey, CA, USA and Sydney, Australia.

- 14,350 coral fragments restored in Nusa Penida, Bali, Indonesia and O'ahu Hawaii.

- 684,000+ tons of CO2 sequestered at our project sites in Southern Cardamom, Cambodia and Paramos Y Bosques, Colombia.

- 35,000 sq-ft of watershed restored at our project sites in Maui, Hawaii, Southern Cardamom, Cambodia and Paramos Y Bosques, Colombia.

Sustainable Development Goals

The impact of SeaTrees on people and planet

SeaTrees Supports Sustainable Development

By restoring, replanting and protecting coastal ecosystems around the world through our core conservation partners, SeaTrees supports both the people and the ecological systems they live in.

SeaTrees supports the 17 United Nations / Sustainable Development Goals (SDGs), which are designed to transform our world for good by 2030. (learn more about the UN SDGs)

Collectively, these projects reduce climate change impacts, increase biodiversity on land and in the sea, protect endangered species on land and ocean, create sustainable jobs, alleviate poverty and hunger, support education and gender equality, and more.

Each SeaTrees project is evaluated annually on its impact, according to all of the SDG metrics that apply. Please see the SDG reports for each SeaTrees project below.
