Global sustainability challenges, such as climate change and the plastics crisis, converge across disciplines and involve diverse stakeholders. Given the magnitude and interconnected nature of sustainability challenges, problem-solvers must be trained across disciplines.

To make the case for mainstreaming ocean sustainability and add to the existing literature, Citigroup carried out an original analysis consisting of two parts: (1) an assessment of impact materiality and revenue exposure for industries and a (2) geospatial analysis to identify potential hotspots of marine natural capital loss.

John Virdin of the Nicholas Institute was one of the expert contributors to this report.

Ocean conservation and sustainable use cannot be pursued or achieved without consideration of the planetary impacts of climate change, and particularly the role of the oceans in both mitigation and adaptation. For this reason, the international community has increasingly committed to providing aid to help finance public goods for ocean conservation and climate action. Although many organizations have set up mechanisms to track both aid and climate finance, such trackers are usually not focused on financial flows related to ocean conservation and climate action.

This whitepaper summarizes the scientific and policy consensus at the ocean-climate nexus, specifically with respect to the role of coral reefs and closely associated tropical coastal ecosystems in climate change processes, and explicitly identifies gaps within key intergovernmental climate and biodiversity policy frameworks that must be addressed to maximize their potential as nature-based solutions during a key decade of conservation action. It concludes with recommendations for national governments and other stakeholders.

Plastic pollution in the ocean is a global problem that requires cooperation from a wide range of groups (e.g., governments, producers, consumers, researchers, civil society). This study aims to synthesize the policy response of governments to the global plastic pollution problem, as a basis for more rigorous monitoring of progress (as called for in Resolution 4/6 of the 2019 United Nations Environment Assembly (UNEA) meeting) and to inform future public policies.

The loss of blue carbon ecosystems results in significant levels of carbon emissions and decreased supply of other ecosystem services. This study aims to provide a first step toward increasing the knowledge of the region’s blue carbon stocks, with a focus on mangroves, and of their financial value based on their carbon storage benefit alone.

The Progress Report on Ocean and Climate Action for 2019 addresses progress (or lack thereof) in nine categories.

In the context of the recently agreed-on United Nations 2030 Agenda for Sustainable Development, which includes the goal to end hunger, achieve food security, and improve nutrition, this report synthesizes the current understanding of capture fisheries’ contributions to food and nutrition security and explores drivers of those contributions. Further, the report examines how ensuring the sustainability of these fisheries—they provide nearly one-fifth of the average per capita animal protein intake for more than 3.1 billion people—and recognizing any synergies between conservation and food security objectives could be important considerations during policy development. 

Recent mass bleachings of coral reefs highlight the need to evaluate the human consequences of such large-scale coral damage—but scientists lack accurate, global, and empirical baseline data on the human dimensions of coral reefs. This article in Biodiversity explores this challenge.
