Pacific governments say an official UN report shows their push for a levy on all shipping emissions – with the revenues redistributed to poorer nations is fairer, cheaper and more effective than other green options under consideration.

 

The report, overseen by a steering committee of 32 governments and published by the International Maritime Organisation (IMO), found that a levy would do less damage to the global economy than a standard for cleaner fuels and, if designed right, could help reduce global economic inequality.

 

Marshall Islands shipping negotiator Albon Ishoda said the analysis showed that a direct levy on emissions is the fastest, cheapest and most equitable wayto decarbonise shipping, a sector that accounts for 3% of the worlds greenhouse gas pollution.

 

A levy would force ship owners to pay for every tonne of greenhouse gases their vessels emit, making the use of more-polluting fuels like todays oil-based bunker fuel more expensive. It would incentive the use of lower-emitting fuels like ammonia, biofuels, methanol and hydrogen.

 

Ishoda said he now expects to see countries coalesce around an emissions levy, adding that alternatives such as relying solely on a fuel standard could be up to twice as damaging for global GDP by 2050, with the poorest countries hit hardest.

 

But written comments on the UN Trade and Development (UNCTAD) report show that Brazil, Argentina and China disputed its findings. Latin American nations have long led opposition to an emissions levy, fearing it will harm their trade-dependent economies.

 

Argentinian officials noted that they were surprisedat the conclusion that levies would lead to less economic damage in the long term while Brazil wrote that this was nonsensical.

 

Argentina said it was policy-prescriptive and therefore unacceptablefor the report to suggest that disbursing the revenues would help developing countries more than developed ones, while China argued this aspect should not have been factored in as the impact assessment should focus on the impact of the measure, rather than the impact after revenue distribution.

Levy or fuel standard?

 

Governments have already agreed to put a price on shipping emissions as a way to reach net zero by or around, i.e. close to 2050. But they have not settled on exactly how to do that, instead tasking experts to study the impacts of various proposals.

 

One proposal which most countries support is a fuel standard that would see ship owners pay for emissions only above a certain level. Owners of ships emitting below this level could potentially sell licenses to those emitting above it, enabling them to continue polluting. This would incentivise shipowners to use cleaner fuels or to save fuel by sailing slower.

 

Some countries like the Pacific island states and many European nations want to combine this fuel standard with a levy, where ship owners would have to pay varying amounts based on their vesselstotal annual greenhouse gas emissions.

 

Under the direction of governments, experts from UNCTAD, the World Maritime University, DNV and Starcrest Consulting Group produced four separate reports, modelling dozens of different scenarios.

 

UNCTAD found that any emissions-cutting scenario would push up the cost of shipping, damaging the global economy by around 0.1-0.2% by 2050. It did not model the economic benefits of how the measures would help curb climate change.

 

Comparing a levy to a fuel standard, the UNCTAD report concluded that in the long run (2050), scenarios that envisage a levy have a smaller impacton economic growth.

 

University College of London academic Tristan Smith, who worked on the paper, explained that the levies modelled lead to greater subsidies for zero-emission fuels and higher incentives for fuel efficiency than the proposed fuel standard. He told Climate Home that this lowers the cost of the transition and therefore the damage to economic growth.

 

Fairer and faster?

 

The report found that a fuel standard without a levy would damage the economies of developing countries particularly small islands (SIDs) and least developed countries (LDCs) more than developed countries because any increase in shipping costs hits the poorest hardest.

 

A high emissions levy of $150-300 per tonne of CO2 equivalent would be fairer, it found, broadly damaging developing countrieseconomies less than developed ones, assuming that the revenues were distributed to poorer nations. Such a levy would actually boost the economies of most LDCs, it found, and damage SIDs less than the alternatives.

 

Consultants from Starcrest interviewed representatives of governments and business in various countries and heard concerns that economies exporting cheap, bulky goods over long distances would be badly hit by an increase in the cost of shipping. It cited Tongas exports of the medicinal kava plant and the USs exports of wood chips as examples.

 

If green measures drive ships to slow down to save fuel, then countries that rely on exporting perishable goods to faraway destinations would suffer, Starcrest was told. Argentinas beef and Chiles cherry industries could be vulnerable.

 

University of Sao Paulo economist Paula Pereda told Climate Home that a levy would quickly reduce emissions, but warned against its potential regressive impacts, which more negatively affect poorer countries and poorer families in all countries.

 

While revenue redistribution could help tackle this unfairness, it could also increase emissions from the compensated households and increase the complexity of the mechanism, she added.

 

Balancing environmental benefits with social equity remains a key challenge in the implementation of carbon tax policies,she said.

 

Governments will debate whether to pursue a levy or fuel standard at the next set of IMO talks in London, starting on September 30. They are aiming to have a measure in place by 2027, which means they will need to agree it at talks in April 2025.
