LNG Ships Cut Emissions 29% in New Study

The global shipping industry just got a powerful new tool in its fight against climate change.

A comprehensive lifecycle study released this month by industry group SGMF shows that ships powered by liquefied natural gas (LNG) can reduce greenhouse gas emissions by up to 29% compared to vessels running on conventional marine gasoil. The research, conducted by environmental consulting firm Sphera, represents the third major assessment of LNG's climate impact.

The results mark a significant improvement over previous findings. Compared to the last study in 2022, the new research shows emissions reductions up to 13% higher than previously calculated.

Eastern Pacific Shipping recently celebrated a milestone that shows this technology is already working at scale. The company completed its 600th LNG refueling operation in April, demonstrating that cleaner shipping fuel isn't just a future promise but a present reality.

The timing couldn't be better. Classification societies DNV and Lloyd's Register also released new LNG fueling reports as a key International Maritime Organization meeting approaches, signaling growing momentum behind cleaner shipping solutions.

Shipping accounts for nearly 3% of global greenhouse gas emissions, making innovations in marine fuel critical for meeting climate goals. LNG offers a practical bridge technology that ships can adopt today while the industry develops zero-emission solutions for tomorrow.

The Ripple Effect

This isn't just about one fuel working better than expected. It's about proving that major industries can dramatically reduce their environmental impact using technologies that already exist.

The shipping industry moves 90% of the world's traded goods. Every percentage point of emissions reduction across thousands of vessels adds up to meaningful climate action. When one of the world's most essential industries finds a way to operate cleaner, it creates a blueprint for others to follow.

The study's improved results also show that clean technology keeps getting better as scientists refine their measurements and companies optimize their operations.

As more shipping companies make the switch and share their results, the path to even cleaner oceans becomes clearer for everyone.
