BAR Technologies has reported that its WindWings system achieves a carbon payback in under six months, following a lifecycle assessment completed through MarineShift360’s ten-month Impact Accelerator programme. The study indicates that each wing, which can cut fuel use by an average of 1.5 tonnes a day and reduce carbon dioxide emissions by 4.7 tonnes daily on many global routes, offsets its embedded emissions in less than half a year. MarineShift360 described the findings as a milestone for transparent sustainability data in maritime design.
“This is a landmark moment for commercial wind propulsion,” said John Cooper, CEO of BAR Technologies. “To demonstrate a sub-six-month carbon payback shows that WindWings is not only delivering immediate environmental benefit but is a commercially ready solution that meets the industry’s urgent decarbonisation needs.”
Will Hopes, simulation and performance engineer, said: “Seeing the payback come out in months has validated our design approach.”
The LCA, carried out to ISO 14044 standards, found that metalwork accounts for 44% of embedded emissions, prompting a shift to recycled-content DH32 steel produced via Electric Arc Furnace processes. Cooper said: “This wasn’t just a validation exercise. It enhanced engineering reviews, procurement decisions, and customer conversations.”
“We have embedded carbon literacy across every function, because sustainable performance must be measurable, verifiable, and repeatable."
BAR Technologies plans to apply carbon-payback metrics across future designs and urged the sector to adopt evidence-based assessment in decarbonisation strategies.
