Global leaders have unveiled a groundbreaking climate tax framework, aiming to cut maritime greenhouse gas emissions by 50% by mid-century. The historic agreement sets a new era for green shipping, with major revenue generated to support the transition to low-carbon fuels.
The International Maritime Organization (IMO) announced that major shipping nations have agreed on a global tax on greenhouse gas emissions, marking a significant step towards reducing the industry’s carbon footprint. The agreement, set to be implemented by 2027, requires cargo ships to use a less carbon-intensive fuel mix or face financial penalties.
The International Maritime Organization (IMO) is a specialized agency of the United Nations responsible for developing and implementing global standards for maritime safety, security, and environmental protection.
Established in 1948, IMO has 174 member states and three associate members.
Its main goal is to promote safe, efficient, and environmentally friendly international shipping practices.
The organization sets regulations on ship design, construction, and operation, as well as rules for crew training and certification.
IMO also works to prevent pollution from ships, including oil spills and waste management.
The Impact of Global Pricing on Maritime Emissions
Shipping accounts for almost 3% of global greenhouse gas emissions, and most of the world’s 100,000 cargo ships are still powered by highly polluting diesel. The agreement aims to cut total annual emissions of greenhouse gases by 50% by mid-century to meet the Paris Agreement goal of a maximal 1.5°C (2.7°F) rise in the average global temperature compared with the pre-industrial era.
“The agreement should signal a turning of the tide on greenhouse gases from global shipping.”
The revenue from the fees, estimated at around $10 billion annually, will go into the IMO‘s net zero fund to invest in fuels and technologies needed to transition to green shipping. The agreement also provides support to developing countries to encourage their transition to lower CO2 emissions in shipping, while offering a ‘reward’ for those reaching zero or near-zero greenhouse gas emissions.

A Divided Industry
The agreement was reached despite several objections. The United States abstained from voting, and major oil producers such as Russia, the United Arab Emirates, and Saudi Arabia voted against it. Environmental groups described the deal as ‘groundbreaking,’ but noted that key aspects of the agreement fall short of what is needed to achieve decarbonization goals.
Environmental groups are organizations that focus on protecting the environment and promoting sustainable practices.
These groups often work to address issues such as climate change, deforestation, and pollution.
They may also advocate for policies and laws that support environmental conservation.
According to a report by the World Wildlife Fund, there are over 7,000 environmental organizations worldwide, with many more emerging every year.
Island nations in the Pacific and Caribbean, vulnerable to the effects of climate change, did not vote for the deal as it was not ambitious enough to reach decarbonization goals. Mark Lutes, the World Wildlife Fund for Nature’s senior advisor, stated that “this agreement should signal a turning of the tide on greenhouse gases from global shipping.” However, he also warned that the transition could be put off course if key aspects of the agreement are not implemented effectively.
A New Era for Green Shipping
The IMO‘s net zero fund will play a crucial role in supporting the transition to green shipping. The organization aims to invest in fuels and technologies needed to reduce emissions, including alternative fuels such as hydrogen and liquefied natural gas. With the global pricing mechanism in place, shipping nations are taking a significant step towards reducing their carbon footprint and contributing to a more sustainable future for the industry.
