Shipping Industry Faces Increasing Climate Change Disruptions: Implications and Responses

The global shipping industry, a crucial player in the transportation of approximately 90% of traded goods, is confronting an escalating series of challenges attributed to climate change. The ramifications of these disruptions are expected to have profound implications for the industry and global supply chains. Here, we delve into the effects of climate change on the shipping sector, industry responses, and potential financial consequences.

Climate-Induced Shipping Disruptions

Mississippi River Low Water Levels: A severe drought has led to a drastic reduction in water levels in the Mississippi River. This condition has caused ships to run aground, requiring intervention by the U.S. Army Corps of Engineers to dredge the river. The impact on commerce is significant.
Panama Canal Backlogs: Recent severe droughts led authorities to reduce the number of daily ship transits through the Panama Canal, resulting in severe supply chain disruptions. A similar reduction in 2019 incurred global shipping losses estimated at up to $370 million.
Low Water Levels in the Mississippi River (2019): Record low water levels in the Mississippi River disrupted the transportation of agricultural goods, resulting in approximately $1 billion in losses.
Container Loss in Bomb Cyclone (2021): In October 2021, 109 shipping containers were washed overboard during a rare "bomb cyclone" off Vancouver Island, Canada.

Climate Threats to the Shipping Industry

Shipping is considered one of the most vulnerable transportation sectors to the effects of climate change. The industry faces a range of climate risks, including tropical storms, inland flooding, sea level rise, drought, and extreme heat. The consequences of these risks are wide-reaching, affecting both ports and global supply chains.

It's estimated that the impacts of climate change on ports alone could cost the shipping industry up to $10 billion annually by 2050 and up to $25 billion per year by 2100, according to a study by RTI International.

Slow Progress in Emissions Reduction

While climate change threatens the industry, the shipping sector has been relatively slow in adopting measures to reduce carbon emissions. In response to these challenges, some companies are introducing innovative solutions:

Maersk, the world's second-largest container ship company, has unveiled its first containership powered by green methanol, which emits fewer carbon emissions than traditional vessels. The company plans to introduce 24 more such ships. However, the adoption of this technology is hindered by the cost and limited availability of the fuel.
Hakan Agnevall, CEO of Wartsila, a global technology and energy company specializing in marine engines, highlights the need for significant investments in the production of green fuels to support new technologies.

Industry Commitment to Net Zero

In July, the international shipping industry made a commitment to achieving net-zero greenhouse gas emissions by 2050. While seen as a significant step forward, experts suggest it may not be enough to meet the goals of the Paris Agreement, specifically limiting global warming to 1.5 degrees Celsius.

Industry Resilience and Planning

To address the immediate and long-term challenges posed by climate change, the shipping industry is focusing on enhancing resilience and planning. For instance:

Maersk is modifying ship designs and enhancing its weather-monitoring systems to better navigate climate-related disruptions.
Wartsila is employing artificial intelligence and digital solutions to integrate weather forecasts, climate data, and logistics information to optimize planning, given increased uncertainty.

In conclusion, the shipping industry is increasingly vulnerable to climate change, with potential consequences for global trade and supply chains. While initiatives to reduce emissions and build resilience are underway, the industry faces substantial challenges in the transition to greener technologies and sustainable practices.
