Researchers conclude that longer wear and using sea freight instead of air can deliver larger climate savings than fibre substitution
MONTREAL — Replacing air freight with sea transport could cut the carbon footprint of fast-fashion cotton and polyester T-shirts by around 30% to 60%, according to a new study by researchers in Canada.
The Concordia University-led research also indicates that doubling a garment’s usable life could reduce associated greenhouse gas emissions by about 50%, because fewer replacement garments are needed.
