Rising Sea Levels Threaten Global Oil Shipment Hubs
Rising sea levels, driven by climate change, pose a severe threat to the global oil shipment infrastructure. According to a report by the China Water Risk (CWR) think tank, many of the world’s largest crude oil terminals are at risk of flooding, potentially disrupting energy security in import-dependent countries such as China, South Korea, and Japan. The report warns that melting ice and rising temperatures could result in multi-metre sea level rises, which would inundate key oil ports and cripple global oil trade.
Vulnerability of Major Ports
A 2021 report by the Intergovernmental Panel on Climate Change (IPCC) predicted that sea levels could rise by more than a meter by the end of this century, with a two-meter rise being a possibility. Low-lying ports and bunkering facilities are particularly vulnerable. The CWR’s “stress test” on maritime infrastructure indicated that 12 out of the top 15 tanker terminals could be affected by a one-meter sea level rise, with five of these ports located in Asia.

Impact on Global Oil Trade
The potential flooding of key oil ports could jeopardize up to 42% of global crude oil exports from major producers like Saudi Arabia, Russia, the United States, and the United Arab Emirates. This would significantly impact 45% of crude shipments to major importers such as China, the United States, South Korea, and the Netherlands. Asian countries, being among the hardest hit, must lead in transitioning from oil dependency and enhancing port infrastructure resilience.
Infrastructure Investment Opportunities
Debra Tan, CWR director and lead author, emphasized the need for investment in resilient infrastructure. “The infrastructure risks highlighted in our report offer unique investment opportunities,” she stated. “We must capitalize on them and wean ourselves off oil: far from providing energy security, our oil habit could sink all our futures.” Both Japan and South Korea import around three-quarters of their crude oil from vulnerable ports, and their receiving ports are similarly at risk.
Long-Term Threats and Strategic Responses
If global temperatures are not kept within the key threshold of 1.5 degrees Celsius, sea level rise could reach three meters, exacerbating the risk to port infrastructure. The ongoing increase in oil output could counterintuitively threaten energy security by contributing to climate change. The report by Lloyd’s Register (LR) and Economist Impact highlighted that a third of the world’s 3,800 ports, especially those in tropical regions, are particularly susceptible to climate change.
Mitigation and Adaptation Strategies
To combat these risks, ports like Shanghai could establish sophisticated flood defense systems similar to the Maeslant Barrier in the Netherlands or the Thames Barrier in London. These systems would provide a long-term solution compared to the short-term and costly approach of frequently raising floodwalls. Additionally, countries need to invest in enhancing the efficiency and resilience of their ports and logistics infrastructure to keep pace with growing import and consumption demands.
Global shipment crisis
The looming global shipment crisis underscores the urgent need for international cooperation and proactive measures to mitigate climate change impacts on critical maritime infrastructure. By investing in resilient port infrastructure and transitioning away from oil dependency, the world can safeguard energy security and ensure the continuity of global trade in the face of rising sea levels.
