Green is the new black - Looking good can be extremely bad for the planet

Global clothing production doubled between 2000 and 2014

Apr 5th 2017

STYLE is supposedly for ever. But the garments needed to conjure up eternal

chic are spending less time on shop racks and in homes than ever before. Global

clothing production doubled between 2000 and 2014, as apparel firms operations

became more efficient, their production cycles became quicker and fashionistas

got more for their money. From just a few collections a year, fast-fashion

brands such as Zara, owned by Spain s Inditex, now offer more than 20; Sweden s

H&M manages up to 16.

Dressing to impress has an environmental cost as well as a financial one. From

the pesticides poured on cotton fields to the washes in which denim is dunked,

making 1kg of fabric generates 23kg of greenhouse gases on average, according

to estimates by McKinsey, a consultancy. Because consumers keep almost every

type of apparel only half as long as they did 15 years ago, these inputs go to

waste faster than ever before. The latest worry is shoppers in the developing

world, who have yet to buy as many clothes as rich-world consumers but are

quickly catching up.

Most apparel companies know that sooner or later, consumers awareness of this

subject will rise. That is a worry. Various furores in the 1990s and afterwards

over the working conditions of people making goods for firms such as Nike,

Walmart and Primark badly damaged brands. The clothing industry cannot afford

to appear so ugly again.

One obvious way in which firms can answer environmental concerns is to use

renewable energy to power their facilities. Beyond that, they can cut back

sharply on water and chemical use; and they can develop new materials and

manufacturing processes that reduce inputs.

The record in this regard is mixed. H&M was the largest buyer in the world of

better cotton last year that is, cotton produced under a scheme to eliminate

the nastiest pesticides and encourage strict water management. It grows in 24

countries and represents about 12% of the 25m tonnes of cotton produced each

year globally. Kirsten Brodde of Greenpeace also notes approvingly that H&M has

eliminated toxic per- and polyfluorinated chemicals from its lines (which is

used to make garments waterproof). Nike s Flyknit method of weaving items,

including trainers, reduces waste by 60% in comparison with cutting and sewing.

Flyknit products have a large following: revenues from the line came to more

than $1bn in the last fiscal year.

But for many clothing companies, research and development into new materials

and methods is not a priority. Plenty do not measure their environmental

impact. And introducing green collections can even carry a risk for brands,

reckons Steven Swartz of McKinsey. It is possible that a shopper will move on

from wearing a consciously green T-shirt to viewing other kinds of clothing as

the trappings of planetary destruction.

A very few brands encourage customers to recycle old clothes by returning them

to stores. But almost all apparel today is made of a mix of materials very

often including polyester. Separating them out is difficult and mechanical

methods of recycling degrade fibres. Chemical methods are too expensive to be

commercially viable. Shipping second-hand clothes off to countries in Africa

and Asia is also a bust. Even if local markets are large enough to absorb them,

the poorer quality of polyester-mixed garbs makes them unappealing.

More durable apparel could help. Tom Cridland, a British designer, creates men

s clothing that is designed to last three decades thanks to strong seams,

special treatments to prevent shrinking and a free mending service. He expects

revenues of $1m this year, but admits that his model will be hard to scale.

Patagonia, a maker of climbing and hiking gear, sends vans to campuses to help

students patch up jackets and trousers. The firm encourages others with

greenery, too. After discovering a type of material for wetsuits that, unlike

neoprene, requires no oil to make, Patagonia shared the find with surfing

brands such as Quiksilver. Such innovation is badly needed. Style may be for

ever. Today s model of clothing production is not.
