The Green Horizon We See Beyond the Big Blue: How Seafarers Will Lead the Just Transition Needed for a Sustainable Shipping Future

By staff - International Transport Workers Federation Seafarer's Section, October 29, 2021

Bush and forest fires, floods, heatwaves, extreme storms and rising sea levels – the life-threatening events which herald dangerous climate change are already taking place around us with increasing frequency. Scientists are clear that humans’ impact on the Earth’s climate is reaching a tipping point beyond which a safe climate is in doubt.

At the heart of the problem is our reliance on greenhouse gas-producing fossil fuels to power industries like shipping, a reliance with a long history. On a global level, international cargo shipping is responsible for about three percent of global greenhouse gas emissions. From the early 1800s, coal was used to fire steam boilers for paddle steamers, which was switched to oil variants when technology improved. Fast forward to today and billions of litres of fossil fuels are used every year to power over 50,000 vessels that keep the world’s supply chain moving.

A Panamax container ship, an averaged sized cargo vessel, consumes about 63,000 gallons (286,403 litres) of marine fuel per day travelling at between 20 and 25 knots.

The global shipping industry must break its dependency on fossil fuels. The rapid expansion of international shipping over the past 50 years has been enabled by the reliance on cheap heavy fuel oil, known as bunker fuel. Key players in the industry have lobbied against restrictions on its use, despite it being one of the most polluting of all fossil fuels.

While it is true that international shipping has low carbon intensity – that is emissions per unit of moved cargo – the total emissions of the industry is very high due to the sheer volume of global maritime shipping. Until now, the focus on carbon intensity as opposed to total carbon emissions has led to false confidence about the carbon footprint of the industry compared to other sectors.

Now that more people are understanding the impact shipping is having on our climate, our industry’s reputation is being damaged. Seafarers want to be able to tell their friends and family that they’re part of a sector taking real and equitable action to curb dangerous climate change. It’s time to act.
