Our Impact

On Earth Day 2021, SeaTrees achieved our first major goal of planting one million SeaTrees across our six SeaTrees 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).


1 Million SeaTrees breaks down as follows:

- 512,000 mangrove trees planted at Biak Island, Indonesia (2019-2021)

- 332,000 mangrove trees planted at Mida Creek, Kenya (2021)

- 205,000 sq-ft of kelp restoration at Palos Verdes, California, USA (2019-2021)

- 6,000 coral fragments restored at Nusa Penida Ped, Bali, Indonesia (2020-2021)

- 15,000 tons of CO2 sequestered Southern Cardamom, Cambodia (2019-2021)

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.
