It might get baffling for companies who are trying to embrace ocean-centric ethics or policies to determine how to save marine ecosystems. Certain values and ideas covered in this chapter can serve as guiding beacons, highlighting principles that can be focused on and incorporated to target ocean sustainability. Through an exploration of case studies, this section aims to unveil the values of decarbonization, long-termism and regeneration (among many others) to show how the adoption of small values amounts to enormous impacts.

Decarbonization stands as a pivotal value in the pursuit of ocean-centric sustainability. As the ocean absorbs excess carbon dioxide, the delicate ecosystem suffers due to increased acidity, which causes disruptions of marine functions. Oceanic acidification, which can be rightly called ‘the evil twin of climate change,’ has increased by almost 30% in the past 200 years and is the fastest known change in oceanic chemistry\[9]. The key role for businesses is to recognize their responsibility to curb carbon emissions and adopt energy-efficient practices, for if changes are not made in the coming 10 years it might be too late. Through decarbonizing measures, enterprises will not only contribute to a healthier planet but also position themselves as leaders in the transition towards a low-carbon future. Eco Wave Power (EWP) is a compelling example of an innovative principle that strongly highlights the value of decarbonization. Their breakthrough technology directly contributes to the reduction of greenhouse gas emissions and transition towards a carbon-neutral future. EWP’s technology taps the natural kinetic energy and immense power of ocean waves to generate clean and renewable electricity. This process eliminates the need for fossil fuels, reducing carbon dioxide and other harmful emissions that are detrimental to both the atmosphere and ocean ecosystems. Specially designed floaters are placed on existing coastal structures like piers or breakwaters. As these floaters move in response to wave motion, they set in motion a hydraulic system that transforms their mechanical energy into hydraulic pressure. This pressure is then transmitted to a land-based hydraulic power unit, where it's converted into rotational motion via hydraulic motors, subsequently driving electrical generators to produce electricity. This pioneering approach can be a game-changer for coastal communities around the globe, enabling them to build a more resilient and harmonious relationship between decarbonized human activities and ocean ecosystems. Another striking case, the PowerBuoy developed by Ocean Power Technologies, deploys a similar mechanism to advance oceanic sustainability. The PowerBuoy's operation involves wave-induced motion, where the up and down movement of ocean waves causes the buoy to move accordingly. This kinetic energy is transformed into mechanical energy, which is then converted into electrical power using onboard generators. The company realizes the huge potential of wave energy, and their relatively simple buoy can produce up to 80,000 terawatt hours. Harnessing wave energy has potential for generating fossil-fuel free energy for floating communities of the future and reduces stress on the ocean so that acidity and other negative impacts from carbon emissions are not aggravated.

Using a nature-based solution for decarbonization, the company Vesta utilizes Olivine rock as a carbon capture mechanism. Olivine, a magnesium-rich rock found abundantly in the Earth's crust, naturally reacts with carbon dioxide (CO2) in the atmosphere through a series of chemical reactions. In this process, Olivine captures carbon dioxide and transforms it into a stable mineral form, ultimately reducing the CO2 concentration in the atmosphere. Further, Vesta uses a method of ‘enhanced weathering,’ by finely crushing Olivine rocks to increase their surface area to allow for more rapid chemical reactions, and thus more carbon dioxide removal due to the increased surface area for carbon to bond with. Vesta’s forward-thinking method leverages the Earth's natural processes to sequester carbon dioxide, and olivine deposits on the beach can also have the added benefit of reduced erosion.

Adopting regenerative practices involves actively restoring and revitalizing marine ecosystems that have been degraded. According to the IUCN Red List of threatened species, over 1550 out of 17903 aquatic species are found at risk of extinction. Moreover, climatic changes around the globe are estimated to impact 41% of the threatened species, leading to large-scale disruptions in the marine ecosystem as well as financial loss. Recognizing the stress on our marine resources as well as the reversing capacity of science, technology, and innovation, the COP15 came up with the Global Biodiversity Framework to transform the society's relationship with biodiversity alongside achieving the agenda for Sustainable Development by 2030.\[10] This requires biological regeneration of restoring marine wildlife and protecting the ocean's capacity as a carbon sink on one hand and economic regeneration of empowering businesses to thrive through designs inspired by nature. The Financing Nature Report of 2019 already pointed out a biological financing gap of US$598bn-824bn per year – the ocean greatly needs our support and attention! The case of Green Wave's regenerative ocean farming exemplifies the value of regeneration through its innovative practice of cultivating seaweed and shellfish in an integrated and diversified marine system. Seaweed serves as a source of protein and acts as a carbon sink by absorbing carbon dioxide from the atmosphere. Stacking beneficial marine functions in this restorative cultivation, shellfish function as filters, absorbing nitrogen from ocean currents. The integration of these organisms within a three-dimensional farming system enhances productivity and efficiency, making it a promising solution to address multiple environmental challenges. In this way the company has been successful in building the first farmer-owned seafood hub. These hubs leverage the plethora of benefits that kelp has to offer, including organic fertilizers, biofuels, livestock feed, bioplastics, and medicines. These farms, thus, do not merely help in food production but are a whole new and useful ecosystem having a range of services, even cleaning industrial wastelands and polluted waterways. Regenerative ocean farming has several benefits over traditional monoculture techniques that often lead to overexploitation of fish stock: these systems operate with zero inputs and require no artificial fertilizers, feed, or pesticides. This method of farming empowers the local community to become active stewards of their marine environment and fosters a sustainable relationship with the ocean. One notable example of community-led waterway restoration \[11] through seaweed cultivation involves a partnership between native communities and a nunnery in the state of New York.

Equity Coupled with Real-World Impact: The effects of environmental and oceanic degradation are more pronounced on the vulnerable communities, indigenous people and small-scale fishermen who rely most on the oceans for their survival. As their access to alternative and adaptive pathways are limited, equity becomes a crucial value in ocean sustainability to ensure fair and just outcome for every stakeholder. To promote this, innovations and initiatives should justify the inclusion of these marginalized communities in the decision-making process and ensure that the benefits of sustainability penetrate to every layer of the society. By addressing the needs of marginalized groups, ocean sustainability efforts can create a more balanced and just approach that benefits both people and the environment. Fish are responding to climate change by moving away from the equator and towards the poles\[12]. The immediate impacts of ocean changes predominantly affect the global south, and the billions of people in this region who rely on the oceans for food and livelihood. Because of the urgency of marine issues, the UN has one entire focus area SDG #14 Life Under\[13] Water devoted to this theme. Moreover, 2021-2030 is the UN Decade for Ocean Sciences\[14]. A commitment to safeguard the marine ecosystem is also seen in the case of Belize's debt-for-nature swap with The Nature Conservancy (TNC). Recognizing the threats to Belize's barrier reef, which harbors exceptional biodiversity, the country embarked on a visionary approach that not only relieved its immediate debt burden but also ensured the long-term health of its marine ecosystem. This swap helped Belize to reduce its external debt by almost 10% of its GDP and helped to mobilize resources for marine conservation. TNC's subsidiary lent funds to Belize, enabling the country to repurchase its $553 million "superbond," which constituted a substantial portion of its external commercial debt. The bond buyback was facilitated at a discounted rate of 55 cents per dollar, effectively reducing the debt burden on Belize. Belize committed to allocate approximately $4 million annually towards marine protection until 2041 and pledged to double its marine-protection parks and expand the coverage of coral reefs, mangroves, and fish-spawning habitats from 15.9 percent to 30 percent by 2026.\[15] Similar visionary work for conservation and working with fishing communities can be seen in National Geographic’s Pristine Seas conservation program. Oceanic sustainability demands solutions that not only address current challenges but also safeguard the well-being of marine ecosystems and communities for generations to come. Restoration projects, such as coral reef rehabilitation or marine protected area establishment, exemplify how equity and real-world impact can be achieved in a long-term vision. These endeavors not only revive habitats but also create resilient ecosystems that can withstand future challenges, enhancing their capacity to support marine life and local economies. Several initiatives have adopted innovations for enduring benefits, as outlined in the below cases.
