The clothes we wear come with their own environmental baggage.
Consider that a cotton T-shirt requires roughly 700 gallons of water to produce. Each year, the production of polyester emits roughly 1.5 trillion pounds of greenhouse gases.
As the fashion industry faces more scrutiny for the environmental impact of its operations, some fashion brands are trying to be more sustainable — and are advertising that to their customers.
Chief among them is global fast-fashion giant H&M, which is aggressively positioning itself as a leader in sustainability.
