Big Blue Conservation - Responsible Tourism

At Big Blue, we strive to ecologically-minded in every way possible. We understand the fragility of our island, and that it is a paradise with limited resources. Through numerous projects and initiatives, we work closely with the local community to sustain our local economy and protect our island from the impact of tourism. By choosing to dive with Big Blue, you contribute to our ecological mission whilst enjoying the best diving on the island.
As a small island with an economy dependant on tourism, we understand that there are many restrictions to living a completely ecologically-friendly life. We endeavour to be an eco-minded resort where possible, such as appropriately managing our waste and reducing our water and electrical consumption. As part of the island community, we aim to contribute to Koh Tao’s value by providing income and the financial incentive to protect the area’s natural environments and local communities through buying locally sourced produce.

Big Blue is a unique dive school in that we contribute to worldwide coral reef research. We have had the privileged to assist internationally renowned marine scientists and assist Masters Students conducting field research with us, such as diver-related damage, the impact of discarded nets on our reefs, and the recovery of corals from mass bleaching events. We are the first dive school on Koh Tao to have a team dedicated to this scientific research, which is essential to formulating the policies and guidelines required to protect our reefs for future generations to enjoy. You can see a list of our publications here.
We strongly believe that communication and sharing of information is the key to the worldwide conservation of our reefs. If you would like know more about how to make your resort more ecologically-friendly, or more about how to implement marine conservation projects such as a coral nursery construction and reef health monitoring projects, please contact us at This email address is being protected from spambots.

Finally, although the island remoteness is one of Koh Tao’s many charms, it does hinder some of our conservation efforts. We aim to be as eco-friendly as possible, but our best of intentions cannot always overcome the reality of some situations. To achieve the best results, we work closely with local communities and are regularly adapting our policies to shifts in local rules, laws and culture, in order try to have a positive effect on our local ecosystem. We are always open to suggestions, so if you have any suggestions to improving our policy, please feel free to contact us – This email address is being protected from spambots.
