Rising Rates Are Reshaping Once-Lucrative Commodity Trades
By Archie Hunter (Bloomberg) — Higher interest rates are forcing commodity traders to rethink some deals and push up prices, in the latest example of how a period of rapid central-bank...
With climate change rapidly opening up the Arctic to shipping, new trade routes could help reduce the shipping industry’s carbon footprint and also weaken Russia’s control in the region, according to a new study conducted by Brown University.
For the study, which was published this week in the Proceedings of the National Academy of Sciences, a pair of climate scientists at Brown University worked with a legal scholar at the University of Maine School of Law to predict how Arctic Ocean ice melt could affect the regulation of shipping routes over the next few decades. They projected that by 2065, the Arctic’s navigability will increase so greatly that it could yield new trade routes in international waters — not only reducing the shipping industry’s carbon footprint but also weakening Russia’s control over trade in the Arctic.
“There’s no scenario in which melting ice in the Arctic is good news,” said Amanda Lynch, the study’s lead author and a professor of Earth, environmental and planetary sciences at Brown. “But the unfortunate reality is that the ice is already retreating, these routes are opening up, and we need to start thinking critically about the legal, environmental and geopolitical implications.”
Lynch, who has studied climate change in the Arctic for nearly 30 years, worked with Xueke Li, a postdoctoral research associate at the Institute at Brown for Environment and Society, to model four navigation scenarios based on four likely outcomes of global actions to halt climate change in the coming years. Their projections showed that unless global leaders successfully constrain warming to 1.5 degrees Celsius over the next 43 years, climate change will likely open up several new routes through international waters by the middle of this century.
According to Charles Norchi — director of the Center for Oceans and Coastal Law at Maine Law, a visiting scholar at Brown’s Watson Institute for International and Public Affairs, and one of the study’s co-authors — those changes could have major implications for world trade and global politics.
Since 1982, the United Nations Convention on the Law of the Sea has given Arctic coastal states enhanced authority over primary shipping routes. Article 234 of the convention states that in the name of “the prevention, reduction and control of marine pollution from vessels,” countries whose coastlines are near Arctic shipping routes have the ability to regulate the route’s maritime traffic, so long as the area remains ice-covered for the majority of the year.
Norchi said that for decades, Russia has used Article 234 for its own economic and geopolitical interests. One Russian law requires all vessels passing through the Northern Sea Route to be piloted by Russians. The country also requires that passing vessels pay tolls and provide advance notice of their plans to use the route. The heavy regulation is one among many reasons why major shipping companies often bypass the route’s heavy regulations and high costs and instead use the Suez and Panama canals — longer, but cheaper and easier, trade routes.
But as the ice near Russia’s northern coast begins to melt, Norchi said, so will the country’s grip on shipping through the Arctic Ocean.
“The Russians will, I’m sure, continue to invoke Article 234, which they will attempt to back up with their might,” Norchi said. “But they will be challenged by the international community, because Article 234 will cease to be applicable if there’s no ice covered-area for most of the year. Not only that, but with melting ice, shipping will move out of Russian territorial waters and into international waters. If that happens, Russia can’t do much, because the outcome is driven by climate change and shipping economics.”
Previous studies have shown that Arctic routes are 30% to 50% shorter than the Suez Canal and Panama Canal routes, with transit time reduced by an estimated 14 to 20 days. That means that if international Arctic waters warm enough to open up new pathways, shipping companies could reduce their greenhouse gas emissions by about 24% compared to traditional routes, while also saving time and money.
“These potential new Arctic routes are a useful thing to consider when you recall the moment when the Ever Given ship was stranded in the Suez Canal, blocking an important shipping route for several weeks,” Lynch said. “Diversifying trade routes — especially considering new routes that can’t be blocked, because they’re not canals — gives the global shipping infrastructure a lot more resiliency.”
Lynch hopes that kicking off the conversation on the Arctic’s trade future with well-researched scholarship might help world leaders make informed decisions about protecting the Earth’s climate from future harm.
“Flagging these coming changes now could help prevent them from emerging as a crisis that has to be resolved rapidly, which almost never turns out well,” Lynch said. “To actually craft international agreements with some forethought and deliberation is certainly a better way to go.”
