Ammonia will ​​play a major role in fighting climate change

The emission-free fuel is key to decarbonizing maritime shipping. Here’s why.

The world economy runs on maritime shipping. More than 80% of international goods by volume are transported by ships, which together weave the essential fabric of the global supply chain.

But all of that shipping comes at a high cost to the climate: Right now, every ship is powered by carbon-emitting fuel, which means maritime shipping is responsible for an estimated 3 percent of all global greenhouse gas emissions. Curbing those emissions as soon as possible—and fully decarbonizing the industry as a whole—is an important piece of the worldwide project to fight climate change and reach net zero emissions by 2050.

Just to get on track, the International Energy Agency (IEA) has concluded that international shipping emissions must remain steady through 2025, then decline by three percent annually until the end of the decade. And the average lifespan of a shipping vessel is 25 years, which means that ships built from 2025 onward will need to run on zero-emission fuel or be powered by engines that are convertible to zero-emission fuel.

We need to build ships that can run on zero-emission fuel, we need to build them as soon as possible, and we need to scale up the production of fuel that will keep those ships running efficiently.
