Is it feasible for the global shipping industry to achieve a net zero carbon emission level by the ambitious target of 2050? This question looms large as we delve into one of the most challenging sectors to decarbonize.
Approximately 90% of the world's trade volume is transported via sea, contributing to a significant 3% of global carbon emissions. The complexity of the industry is undeniable, with some companies owning hundreds of container ships while others, like many Greek families, operate with just one or two vessels. The decarbonization solution must cater to both ends of this spectrum.
Consider the contrasting operational styles of these ships: large container vessels traverse the globe on fixed schedules, while the smaller Greek-owned bulk carriers are more flexible, akin to taxis ready to go anywhere in the world. The uncertainty of fuel availability is a major concern for these smaller operators, who might shy away from adopting new fuels if they're not universally available.
The United Nations International Maritime Organisation (IMO), based in London, has set a target for the sector to achieve net zero carbon emissions by 2050. New rules to enforce this are expected to be approved next year and in place by 2027. However, the specifics of these rules are yet to be decided, leaving many ship owners in limbo.
The options for alternative fuels are diverse and challenging. Methanol is costly, ammonia is toxic, and hydrogen requires vast amounts of space. High-tech sails are gaining traction, but liquified natural gas remains a popular choice for some vessels due to its lower carbon emissions per unit of energy.
The fear among ship owners is that they might invest in new technologies only to find that the necessary fuels aren't being produced, rendering their multi-million-dollar investments obsolete. Moreover, the risk of competitors continuing to use cheaper, traditional fuels while others bear the brunt of high costs for low-carbon fuels adds another layer of complexity.
Despite these challenges, there are reasons for optimism. The IMO's commitment to robust rules covering all types of ships is still uncertain, but ship owners have already started adjusting their voyages to reduce carbon emissions since January this year, whenever they arrive in a European port. Additionally, ships capable of using ammonia or methanol as fuel are emerging from Asia's shipyards.
The future of clean shipping hangs in the balance. If the right incentives are put in place, there's a strong likelihood that ship owners will invest in cleaner technologies. However, if the process is botched, there's a real risk that ships will continue to contribute to global warming for decades to come. The clock is ticking, and the journey to net zero emissions in the shipping industry is fraught with challenges and uncertainties.
