What: Fast-fashion sees a decline as consumers become more sustainably aware.

Why it is important: Apparel companies seen as bad for the environment face "reputational risk."

According to a UBS survey, fast-fashion retailers could face revenue declines of 10% to 30% over the next 5 to 10 years as more consumers become aware of the environmental and human costs of apparel production.

Apparel companies in fast fashion, like H&M, are addressing consumer concerns through experimentation with textiles and releasing eco-minded collections.These siloed efforts might not be enough. Consumers are becoming more aware about the impact their clothing choices have on the environment. This has resulted in a change of buying behaviour to focus on buying less and invest in more sustainable pieces.

Fast fashion faces steep declines in the next decade or sooner
