Why ‘eco-conscious’ fashion brands can continue to increase emissions

Exclusive: Nike and H&M are among firms whose environmental scores suggest progress. But how are these calculated?

Fashion accounts for 10% of the world's carbon emissions and is the second-most polluting industry in the world. But in an increasingly climate-conscious society, it is increasingly trying to present itself as sustainable to appeal to customers.

One big target is reducing greenhouse gas emissions and for the past two decades many brands have signed up to a scheme called the Carbon Disclosure Project (CDP), an independent body that awards grades for environmental performance.
