Trans-Pacific shipping is the busiest container shipping lane in the world
The environmental impact of maritime shipping is significant, and the global community recognizes the need for international cooperation to address this issue. The Association of Southeast Asian Nations (ASEAN) has set a goal for its members to be carbon neutral by 2050. The EC-IMO Energy Efficiency Project aims to establish Maritime Technology Cooperation Centres in 5 regions to promote low-carbon technologies and operations in maritime transport.
Shipping-related GHG emissions rose by 4.9% in 2021, and emissions are expected to double by 2050 if no action is taken. The largest retail companies, such as Walmart and Amazon, have significant carbon footprints due to their shipping practices, and they are working towards reducing their shipping-related emissions. For example, IKEA, which came in seventh place for CO2 output, is committed to reducing its carbon footprint from each shipment by 70% on average by 2030.
To reduce emissions, some strategies being explored include the adoption of slow steaming, where the operational speed of ships is reduced, saving fuel and lowering CO2 and air pollutant emissions. Another strategy is the use of shore power systems, where ships connect to shore power instead of relying on their generator engines while moored at ports, which can improve air quality in port cities. Additionally, the first trans-Pacific zero-carbon container ships are expected to be introduced by 2030.
The environmental impact of shipping extends beyond just GHG emissions. Oil spills, whether accidental or intentional, have caused significant harm to marine environments, with the Exxon Valdez grounding in 1989 and the Sanchi oil spill in 2018 being notable examples. Noise pollution from ships can also travel long distances, disrupting the ability of marine species, such as whales, to communicate and survive.

The shipping industry is responsible for 3% of global greenhouse gas emissions
The shipping industry is a major contributor to global carbon emissions. In 2022, the industry was responsible for approximately 3% of global greenhouse gas emissions, making it the second-largest contributor to carbon pollution after the aviation industry. With the anticipated growth in the industry, this figure could rise to 10% by 2050.
The carbon emissions from the shipping industry are primarily due to the combustion of fossil fuels like marine gas oil and heavy fuel oil (HFO). These fuels release harmful gases, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), contributing to climate change. In addition to greenhouse gases, ships also emit significant amounts of nitrogen oxides (NOx) and sulfur oxides (SOx).
The impact of the shipping industry on the environment is significant, especially considering that about 80% of everything bought and sold travels on oil-burning, seafaring freighters at some point. The International Maritime Organization (IMO), which regulates the industry, has implemented measures to curb cargo ship emissions and reduce fuel consumption. However, experts argue that stronger regulations and bigger investments are needed to transition to cleaner technologies and fuels.
To reduce emissions, some possible solutions include slow steaming, which involves reducing the speed of cargo ships, leveraging technological innovations to improve fuel efficiency, and transitioning to zero-carbon or low-carbon fuels and vessels. There have been efforts to establish green shipping corridors, such as the partnership between the ports of Shanghai and Los Angeles, with the aim of improving air quality and reducing emissions along the world's busiest container shipping route.
The transition to cleaner technologies and fuels in the shipping industry comes with substantial costs and challenges. However, it is crucial to address these emissions to mitigate the impact of the industry on the environment and to meet the temperature goals set by the Paris Agreement and the IMO's climate strategy.

Retail giants are the biggest polluters, with Walmart topping the list
The trans-Pacific corridor is the world's busiest container shipping lane, and it is responsible for a significant amount of pollution. The exact impact of trans-Pacific shipping on the environment is challenging to trace, as it involves numerous companies, countries, and cargo carriers. However, it is clear that the shipping industry contributes considerably to global emissions.
Retail giants are among the biggest polluters in the shipping industry. A recent report by Pacific Environment and Stand.earth revealed that 15 major corporations emit as much climate pollution from overseas shipping as 1.5 million American homes. These companies include Walmart, Target, Ikea, and Amazon, and Home Depot and Nike. Notably, Walmart tops the list as the largest retail company in the United States and the biggest polluter among the 15 retailers studied. Madeline Rose, the lead author of the report, stated that "these retail giants' dirty ocean shipping is fueling the climate crisis."
Walmart's emissions are significant, with The Verge reporting that the company generates more greenhouse gas than a coal plant would in a year. This is largely due to Walmart's overseas shipping, as the company primarily imports goods from China to the West Coast. While Walmart has stated its goal to eliminate its carbon footprint by 2040, this does not include emissions from its entire supply chain, particularly those released by overseas shipping.
Other retail giants have also come under scrutiny for their contributions to pollution. Amazon, for example, has pledged to prioritize transportation to reach net-zero carbon by 2040, but critics argue that this is merely a long-term empty pledge. Similarly, Ikea has announced plans to become "climate positive" by 2030, but its shipping still accounts for about 40% of its total carbon emissions from transportation. Target, on the other hand, has set a net-zero enterprise goal for 2040 that considers its entire supply chain.
The impact of these retail giants' shipping-related emissions is far-reaching. As Madeline Rose stated, "Major retail companies are directly responsible for the dirty air that sickens our youth with asthma, leads to thousands of premature deaths a year in U.S. port communities, and adds to the climate emergency." With the growing demand for imported goods, it is essential for companies to address their carbon footprints and find sustainable solutions for their shipping practices.

The first trans-Pacific zero-carbon container ships are expected by 2030
Trans-Pacific shipping is highly polluting. The trans-Pacific corridor is the world's busiest container shipping lane. A seagoing container vessel pollutes as much as 50 million cars. The world's 17 largest ships emit more sulphur than the global car fleet.
Despite growing efforts to adopt more sustainable fuels and strategies, shipping-related GHG emissions rose by 4.9% in 2021. Shipping emissions are expected to double by 2050 if the current trajectory continues.
To tackle this issue, the cities of Shanghai and Los Angeles have partnered to create the Green Shipping Corridor, joining the two ports as part of the C40 Green Ports Forum. The initiative aims to connect major port cities worldwide to implement greener solutions and mitigate air pollution and GHG emissions.
The first trans-Pacific zero-carbon container ships are expected to be introduced by 2030. The partnership focuses on phasing out fossil fuel-powered vessels and increasing the adoption of low- and zero-carbon fuel ships and technologies through the 2020s. The ports of Los Angeles, Long Beach, and Shanghai, along with major carriers, have outlined plans for the first major trans-Pacific green shipping corridor. The Green Shipping Corridor Implementation Plan Outline aims to accelerate emissions reductions across one of the world's busiest container shipping routes.
The initiative has received support from organizations like C40, which has established targets for deploying ships with lower or zero lifetime emissions on the route by 2025. Mark Watts, C40's executive director, emphasized that the corridor plan demonstrates the scalability of green shipping and the multiple benefits it brings, including cleaner air, less noise, and more local jobs.

Slow steaming is a cost-effective way to reduce CO2 emissions
Trans-Pacific shipping is a major contributor to global carbon emissions. The trans-Pacific corridor is the busiest container shipping lane in the world, with 25.1 million twenty-foot equivalent units (TEU) traded between East Asia and North America in 2020. This shipping activity accounts for nearly 3% of the world's annual greenhouse gas emissions, as well as a significant share of air pollution in coastal communities.
International shipping is a major source of water and air pollution and has been directly linked to marine and coastal environmental deterioration. It is the third-highest anthropogenic sulfur oxide (SOx) emitter globally, after power plants and industry. In addition, nitrogen oxide (NOx) emissions from ships are also a significant concern, with 18.6 million tons emitted annually.
To address these environmental impacts, the International Maritime Organization (IMO) has been working to reduce emissions from international shipping since it was tasked with doing so by the 1997 Kyoto Protocol. While an IMO action plan on market-based measures has been in place for 10 years, the organization remains years away from implementing a measure to reduce emissions.
One effective measure to reduce emissions from trans-Pacific shipping is slow steaming. Slow steaming is a cost-effective and practical way to reduce greenhouse gas emissions and air pollution from shipping. By reducing the speed of ships, slow steaming decreases fuel consumption and, in turn, lowers CO2 emissions. This approach has been studied using the example of a container ship sailing through the Mediterranean Sea, demonstrating that slow steaming can dramatically reduce CO2 emissions and even save the sector money.
The benefits of slow steaming have also been observed in the liner shipping industry, where it has become increasingly common as fuel prices have risen. Slow steaming provides the added flexibility that the industry needs, and it can be implemented in a way that raises revenues for climate change purposes.
In conclusion, slow steaming is a cost-effective and practical solution to reduce CO2 emissions from trans-Pacific shipping. By reducing the speed of ships, fuel consumption and emissions are lowered, providing both environmental and economic benefits. With the ongoing environmental impacts of trans-Pacific shipping, slow steaming offers a much-needed measure to mitigate the industry's carbon footprint.
