Discover how a global carbon tax on shipping emissions can reshape the maritime industry and drive serious progress in climate action.
Introduction
The shipping industry is a major contributor to global greenhouse gas (GHG) emissions, accounting for nearly 3% of total global emissions. With international trade heavily dependent on maritime transport, the sector has remained largely unregulated in terms of carbon pricing—until now.
The Global Carbon Tax on Shipping Emissions is gaining momentum as world leaders, environmental groups, and climate scientists recognize the urgent need for decarbonizing shipping. Implementing such a tax could significantly influence shipping routes, freight costs, and climate progress.
In this article, we dive into what this carbon tax means, how it works, the potential impacts on global trade, and how initiatives like Carbonil by NetZero India can support businesses and nations in transitioning toward greener practices.
Why the Shipping Industry Is Under Scrutiny
Shipping has been a cornerstone of global commerce. Approximately 90% of global trade is carried by sea. However, it’s also been a carbon blind spot. Ships burn bunker fuel, one of the dirtiest fossil fuels, leading to millions of tons of CO₂ and other pollutants being released annually.
The International Maritime Organization (IMO) had previously set targets to cut GHG emissions by at least 50% by 2050, but critics argue that this is not enough. A global carbon tax on shipping emissions is being proposed as a much-needed market mechanism to reduce emissions and speed up innovation.
What Is a Global Carbon Tax on Shipping Emissions?
A carbon tax on shipping would charge vessels based on the amount of carbon dioxide they emit per voyage. The money collected could be reinvested in green technologies such as:
- Green hydrogen and ammonia fuels
- Wind-assisted propulsion
- Energy-efficient ship designs
This tax would make high-emission shipping more expensive, pushing companies to innovate and adopt cleaner alternatives.

How Much Could It Cost?
Proposals for a carbon levy have ranged from $100 to $150 per ton of CO₂ emitted. For context, a standard cargo ship traveling from China to Europe can emit about 10,000 tons of CO₂ per round trip.
At $100 per ton, that’s an additional $1 million per voyage—a cost that could be absorbed by freight companies or passed on to consumers.
Global Support and Opposition
🌟 Supporters
- Pacific Island nations that are highly vulnerable to climate change.
- The European Union, which is already expanding its Emissions Trading Scheme (ETS) to include maritime transport.
- Environmental NGOs like Transport & Environment that advocate for cleaner shipping.
🚫 Opposition
- Some developing nations and shipping corporations worry that the tax could increase prices on essential goods.
- Countries heavily reliant on exports may feel economic pressure due to higher freight rates.
Environmental Benefits
If implemented globally, a carbon tax could reduce shipping emissions by up to 20% by 2030, according to a report by the World Bank.
Additional benefits:
- Encouragement of eco-friendly ships
- Investment in low-emission ports
- Better fuel efficiency and routing optimization

India’s Position on the Carbon Tax
India, a global shipping hub with major ports like Mumbai and Chennai, has expressed a balanced view:
- Supports the IMO’s decarbonization targets
- Calls for flexibility and financial aid to help developing nations transition
- Encourages public-private partnerships in green port and fuel initiatives
India-based startups and organizations such as NetZero India are actively working on innovative solutions like carbon tracking tools, green fuel research, and sustainable logistics.
