Climate change: Can working boats hit net zero target?

Turning our waters greener is an emerging theme at industry shows like Seawork in Southampton.

It brings together exhibitors from around the world to put on show the latest technologies. In between the networking and trade there is talk about how to decarbonise the sector

"Reducing use of fossil fuels is the first stop." says Seawork organiser Andrew Webster.

"Optimising the way engines are being used, including the use of AI. And then different fuels like hydrogen or ammonia or battery."

For larger vessels - like those built by Isle of Wight company Diverse Marine - advancements in engine efficiency are playing a key role.

But Simon Thomson, international business development director, warns there is no single solution for how the sector hits its target.

"If we can refine the fuel, refine the system, reduce the carbon output - then it has to be a benefit. But it's a problem - I don't think anybody can answer that question."
