Term SOTD (Sustainable Ocean Tourism Development) refers to the tourism industry's economic growth through the environmental protection and management of natural resources.

SOTD not only refers to sustainable environmental development for the ocean but also includes the highly developed tourism industry in lake and river areas. OACM began to develop the SOTD strategy in 2013, aiming to re-introduce the tourism industry to the most fundamental service of clean oceans and safe marine areas for tourists. These were the basics of the SOTD concept and strategy - which have now been globally introduced and are in the integration phase for every segment of the tourism and travel industry. The main purpose is to minimise the global plastic print the industry leaves behind and it is essential for the tourism industry to integrate OACM SOS CP (Sustainable Ocean Solutions Conservancy Program) into its ethical, moral and responsibility codes in order to have a concrete impact on the oceans and world’s natural resources.

OACM SOTD program is oriented towards minimising negative impacts upon the natural and socio-cultural environment, and the protection of biodiversity and ecological processes - which is the essence of the ocean tourism industry. By protecting these areas, OACM is providing and generating economic benefits for host communities, organizations and authorities managing natural areas with conservation purposes. OACM SOTD with the SOS CP and the GEPN system is increasing awareness about the conservation of natural and cultural assets, both among locals and tourists.
