On Friday, 11 April, the Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO) agreed upon a set of mid-term measures to get the sector on track to net-zero by 2050. This follows the global shipping regulator’s earlier implementation of short-term measures focused on fuel efficiency. The package is due to be adopted by October 2025, with details and implementation guidelines to be specified and approved in spring 2026, before being included in the MARPOL treaty and coming into force in 2027.
The most important elements of the net-zero framework are:
But the policy fails to introduce a pricing mechanism covering all shipping emissions
Although the willingness to make progress on pricing measures is encouraging, the proposed framework doesn’t introduce full carbon pricing as implemented under the European Union’s ETS for shipping. This would only make bunker fuel less attractive, it generates much more budget to support greening as well. Several market players, including leading global container liners and shippers such as Cargill and Trafigura, have previously advocated for putting a price on all emissions as this could be a forceful instrument to support decarbonisation. Maersk called for a levy starting from $150-200 and preferably even significantly higher to support the transition.
However, this also raises the costs of shipping, and adopting this was probably not achievable at the global level at this point. From an economic point of view, though, this would ultimately be necessary to narrow the gap between bunker fuels and costlier renewable fuels like green methanol and ammonia, and support investments in infrastructure and availability.
Fuel neutrality risks putting biofuels at the forefront
The net-zero framework takes a well-to-wake approach and looks at the greenhouse gas intensity of the fuels that companies use. It’s still unclear which fuel options will be eligible for subsidies and to what amount, but the agreement doesn’t exclude alternative fuels (and includes LNG as well). As such, companies are also allowed to use biofuels, which are often the cheapest and easiest lower-carbon option as they can be used in the existing fleet and don’t require investments in new technology. This will boost demand while demand from the aviation sector also starts to mount. It also raises questions about controversial (first-generation) feedstocks without specific requirements. Moreover, it could distract from investments in alternatives.
Targets fall short of earlier ambitions
In terms of target setting, the IMO previously adopted a goal of reducing GHG emissions by 20%, striving for 30% by 2030, and 70%, striving for 80% by 2040, both compared to 2008. The adopted framework seems to focus on a reduction of at least 8%-21% by 2030, which looks less ambitious. At the same time, total absolute emissions in shipping have risen in recent years, underscoring the need for more decisive action.
All in all, I believe this framework is a step in the right direction, but it should also be seen as a framework to build upon further down the line.
