Fossil fuels account for 5% of global oil production
The shipping industry is one of the world's greatest polluters, with international shipping accounting for about 2.2% to 3% of global greenhouse gas emissions. In 2018, global shipping activity emitted roughly 1.05 billion tons of carbon dioxide into the atmosphere, accounting for about 2.9% of total global anthropogenic CO2 emissions for that year.
According to Camille Bourgeon, a specialist in air pollution and energy efficiency in the marine environment at the IMO, the shipping industry uses more than 300 million tons of fossil fuels annually, which is roughly 5% of global oil production. Additionally, about 40% of maritime trade consists of fossil fuels or chemicals derived directly from fossil fuels. This includes oil, gas, coal, and other fossil fuels, making shipping a key player in the global fossil fuel supply chain.
The combustion of heavy fuel oil (HFO) by ships releases harmful gases, including carbon dioxide, methane, and nitrous oxide, contributing to climate change. Furthermore, ships produce sulfur oxide (SOx) emissions, which pose significant environmental and health risks. The International Maritime Organization (IMO) has recognized the need for change and has set targets to reduce shipping emissions, aiming for net-zero emissions by 2050.
To achieve this goal, the IMO is considering policy measures such as a greenhouse gas levy and a green fuels mandate. The organization also encourages the use of renewable energy, cleaner fuels like LNG and hydrogen, optimized ship design, slow steaming, and technology for route optimization. The transition to cleaner fuels and more efficient practices will not only reduce emissions but also save money and potentially reduce the number of ships in operation.

Shipping emitted 1.05 billion tons of CO2 in 2018
The shipping industry is a significant contributor to global carbon dioxide (CO₂) emissions. In 2018, the industry emitted approximately 1.05 billion tons of CO2 into the atmosphere, according to the International Maritime Organization's (IMO) 2020 greenhouse gas study. This accounted for about 2.9% of total global anthropogenic CO2 emissions that year. The IMO has reported a steady increase in CO2 emissions from the shipping industry, with a total of 977 million tons emitted in 2012, rising to 1,076 million tons in 2018, representing a 9.6% increase.
The shipping industry's carbon footprint is influenced by various factors, including the size and type of ships, their deadweight capacity, energy efficiency, fuel type, and annual travel distances. Cargo ships, for example, produce 16.14 grams of CO2 per kilometer for each metric ton of cargo. The type of cargo carried also plays a role; by weight, 40% of maritime trade consists of fossil fuels or chemicals derived from them.
Recognizing the environmental impact of maritime shipping, the IMO and other organizations have implemented initiatives to reduce emissions. These include setting ambitious targets for net-zero emissions by 2050, promoting renewable energy sources, transitioning to cleaner fuels like LNG and hydrogen, optimizing ship design, implementing slow steaming, and enforcing regulations such as the Energy Efficiency Existing Ship Index (EEXI) and Carbon Intensity Indicator (CII).
While these efforts are underway, the shipping industry continues to face challenges in decarbonization. As global commerce expands, transoceanic shipping will likely increase, requiring further measures to mitigate its environmental footprint. The transition to alternative fuels and technologies is crucial, and companies are exploring options like methanol, wind power, and hull-cleaning robots. However, the majority of the fleet still relies on burning oil, and external factors, such as regional conflicts and droughts, can impact shipping routes and emissions.

40% of maritime trade is fossil fuels
The shipping industry is responsible for a significant amount of global carbon dioxide (CO2) emissions, with cargo ships emitting around 3% of the world's greenhouse gases. While this is a notable contribution, the contents of their cargo holds are even more concerning. By weight, 40% of maritime trade consists of fossil fuels or chemicals derived directly from fossil fuels. This includes coal, oil, gas, and petrochemicals, which together account for nearly 4,500 million tons out of the 11,000 million tons of total maritime shipping.
The combustion of heavy fuel oil (HFO) and marine gas oil, commonly used by ships, releases harmful gases such as carbon dioxide, methane, and nitrous oxide, contributing to climate change. In addition, ships produce sulfur oxide emissions, which pose significant environmental and health risks. As global commerce continues to expand, the demand for transoceanic shipping will also increase, exacerbating these issues.
To address these challenges, the International Maritime Organization (IMO) has set ambitious targets to reduce emissions and achieve net-zero emissions by 2050. This includes implementing regulations, transitioning to cleaner fuels, optimizing ship design, and exploring renewable energy sources.
While the transition to cleaner energy sources is crucial, it is important to recognize that even with a shift to solar and wind power, the transportation of equipment for these energy sources will still rely on shipping. However, climate activist Bill McKibben offers a positive perspective, suggesting that the transition could potentially reduce the number of ships in operation by almost half.
As the shipping industry navigates the path toward decarbonization, it is exploring various alternatives, including hydrogen as a shipping fuel. While hydrogen has the potential to be a clean fuel, the method of production significantly impacts its environmental footprint. Gray hydrogen, produced from reforming natural gas or other fossil fuels, accounts for about 95% of global hydrogen production and has a higher carbon footprint than green hydrogen, made from renewable energy sources.

IMO targets net-zero emissions by 2050
The shipping industry is a major contributor to global carbon dioxide (CO2) emissions, accounting for about 3% of the world's greenhouse gas emissions. The combustion of heavy fuel oils (HFO) and other fossil fuels used by ships releases harmful gases such as carbon dioxide, methane, and nitrous oxide, contributing to climate change. In addition, ships produce sulfur oxide emissions, which pose significant environmental and health risks. As global commerce continues to grow, the shipping industry's fuel consumption and emissions will also increase.
Recognizing the need to address this issue, the International Maritime Organization (IMO) has set a target of achieving net-zero emissions from international shipping by 2050. The IMO Net-Zero Framework combines mandatory emissions limits and GHG pricing across the entire industry sector. This framework includes a new fuel standard for ships and a global pricing mechanism for emissions, which will be formally adopted in October 2025 and enter into force in 2027. The IMO's strategy sets indicative checkpoints for reducing emissions, with targets of a 20% reduction by 2030 and a 70% reduction by 2040, striving for 30% and 80% respectively.
To achieve these targets, the IMO has proposed several initiatives. These include harnessing renewable energy sources, transitioning to cleaner fuels such as LNG and hydrogen, optimizing ship design for efficiency, implementing slow steaming, and using technology for route optimization.
