Based on SDG 14 “Conserve and sustainably use the oceans, seas and marine resources for sustainable development” the investable sub-goals are:

14.1 Prevent and significantly reduce marine pollution of all kinds
Marine products, services and equipment providers
Investible entities that:
- provide products and services with focus on reducing marine pollution (e.g. ecological surveys and lab testing, oil spill response)
Water pollution prevention
Investible entities that:
- provide products and services with focus on preventing water pollution (through agricultural run-off, discharge of nutrients and pesticides, untreated sewage)
14.2 Sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts
Sustainable fishing
Investible entities that:
- provide products and services with focus on sustainable fishing (e.g. surveillance equipment, sustainable fishing technologies, nets for lower by-catch, certification)
- provide products and services for fish farming in ponds or indoor basins
!Beware of trawlers for indiscriminate industrial fishing.
!Fish farming or aquaculture with open connection to open sea is controversial
The SDGs and SDG sub-goals have been translated from an investor perspective into the SDI taxonomy of product categories that are considered solutions contributing to the SDGs. The full SDI Taxonomy can be found here. When evaluating a company, the starting point is the classification of its products and services within the SDI product categories. The size of the positive contribution is calculated from the associated revenues (sales).
