US EditionStudy Finds Ocean Damage Nearly Doubles Climate Cost Estimates
Including ocean damage raises the social cost of carbon by 91%, adding $46.2 per ton and highlighting risks to fisheries, coastal communities, and small economies, study finds.
- On Thursday, researchers at the Scripps Institution of Oceanography at the University of California San Diego published a study finding ocean damage nearly doubles the social cost of carbon, adding $46.2 per ton to reach $97.2 per ton, a 91% increase.
- Because the ocean was omitted from standard models, the team noted it had never been included in social cost of carbon calculations despite damage to coral reefs, fisheries and coastal infrastructure affecting millions globally.
- Using integrated assessment models, the researchers incorporated impacts on coral reefs, mangroves, fisheries and seaports, accounting for lost fisheries revenue, trade, and reduced calcium, omega-3 fatty acids, protein and iron availability.
- Immediate costs accrue to fisheries and coastal infrastructure because 2024 emissions of 41.6 billion tons imply nearly $2 trillion in ocean damages, disproportionately affecting vulnerable regions, researchers said.
- By quantifying ocean harms, the paper positions the blue social cost of carbon as a more complete metric, with researchers saying it gives decision-makers a fuller cost–benefit tool than carbon credits and offsets.

Accounting for ocean impacts nearly doubles the social cost of carbon - Nature Climate Change
Oceans provide essential benefits to people and the economy, underpinned by the extent and condition of marine ecosystems and infrastructure—or ‘blue’ capital. However, the impacts of climate change on blue capital have been largely overlooked in influential indicators such as the social cost of carbon (SCC). Here we integrate the latest ocean science and economics into a climate-economy model, capturing climate change impacts on corals, mangrov…

Study Finds Ocean Impacts Nearly Double Economic Cost of Climate Change
For the first time, a study from researchers at Scripps Institution of Oceanography at the University of California San Diego integrates climate-related damages to the ocean into the social cost of carbon— a measure of economic harm caused by greenhouse gas emissions.
Damage to the ocean nearly doubles economic cost of climate change, new study finds - Regional Media News
(NEW YORK) - Scientists have factored damage to the ocean into the social cost of carbon for the first time - finding it nearly doubles the economic impact from climate change. Ocean damage from climate change - dubbed the "blue" social cost of carbon - causes the global cost of carbon dioxide emissions to society to nearly double, according to new findings by researchers at the Scripps Institution of Oceanography at the University of California…
