The global shipping industry is on a path to net zero

Mark Dickinson of the Nautilus International trade union responds to an editorial about the environmental harm caused by cruise ships

Your editorial on cruise ships (26 November) asserts that the International Maritime Organization’s carbon-reduction targets “do not put it on a path to net zero”. We disagree. In July 2023, the IMO adopted a revised greenhouse gas strategy committing the global shipping industry to achieving net zero greenhouse gas emissions by 2050. This includes ambitious checkpoints for 2030 and 2040.

You also advocate for mandatory adoption of green technologies and the imposition of green taxes. It is worth noting that a global carbon levy is already part of the measures set to become mandatory in 2025 via amendments to the Marpol convention. Since 2011, this instrument has included binding provisions on greenhouse gas emissions. Additionally, the use of shore power, which reduces reliance on ship engines while moored, is increasingly mandated by ports, with EU regulations coming into effect by 2030 to make shore power compulsory for passenger vessels in major European ports.

As a trade union representing maritime professionals working on cruise ships, we fully support efforts to reduce the environmental impact of shipping and cruising. We have been vocal critics of ship owners who have dragged their heels in adopting sustainable practices.

Much progress remains to be made. Still, it is essential to recognise the significant strides taken and the role of our members in driving further change. Constructive engagement will be critical to achieving the shared goal of a more sustainable maritime sector.
