On July 7, 2026, researchers from CSIRO revealed surprising findings about the carbon footprint of wool garments, highlighting that more than half of the emissions from a wool suit come from methane produced by sheep. This discovery emerged during a collaboration between the menswear brand MJ Bale and CSIRO scientists, aiming to enhance sustainability in the wool industry.
Methane Emissions and Wool's Carbon Footprint
The analysis conducted by MJ Bale indicated that a staggering 52% of emissions from their flagship Kingston suit originated from methane. This revelation shifted their focus towards finding innovative solutions to mitigate these emissions, particularly through changes in sheep diet.
During a design sprint in May 2023, MJ Bale and CSIRO researchers brainstormed strategies to address the methane issue. The team considered the potential of a seaweed supplement called asparagopsis, developed by CSIRO, which has shown promise in reducing methane production in livestock.
Innovative Solutions for Measuring Emissions
Dr. Cesca McInerney, a key member of the CSIRO team, proposed an intriguing method to measure methane emissions indirectly through the wool itself, rather than through traditional and costly breath measurement techniques. This innovative approach could revolutionize how the wool industry monitors and manages its environmental impact.
