ARTEM BELIAIKIN ON UNSPLASH

IN its, Swedish retailer (H&M) identified one trend as a 鈥渉igh鈥 risk to its business for the first time, higher-risk even than increased energy costs or availability of raw materials. Should consumers increasingly prefer 鈥減roducts and services with low climate impacts from trusted companies that are seen as leaders in sustainability,鈥 H&M wrote, the company might see a negative impact. If H&M were not seen as a climate leader, it could face 鈥渞eputational risks related to brand perception.鈥

H&M brought the subject up again a few pages later, this time in sunnier terms: 鈥淭here is an opportunity,鈥 the report noted, 鈥渇or H&M Group to attract more customers by providing a more sustainable and transparent offering.鈥

As recently as 2018, H&M didn鈥檛 list sustainably minded shopping as a risk at all. But the past few years have seen tough feedback for fashion companies that push the limits on how quickly they can churn out clothing and accessories, alongside demands for more transparency. Retailers like Shein, H&M, Zara, and Boohoo have been repeatedly dinged by consumers, activists, the press, and public officials for their mounting climate, water, and plastic , for , and for . Meanwhile, report after report shows when it comes to purchasing decisions. In one 2021 survey, for example, two thirds of US consumers .

But people don鈥檛 always shop their values. For all the talk about shifting shopping patterns, there is no clear quantitative evidence of any demographic ditching fast fashion en masse 鈥 not even . That leaves retailers whose business model relies on fast fashion to size up the threat against it in their annual reports, sustainability reports, and climate disclosures, where little consensus exists. It鈥檚 clear that shopping habits could change, but no one is sure how, when or if a more climate-conscious consumer will be good or bad for business.

WHAT BACKLASH?
Born in the 1990s, 鈥渇ast fashion鈥 broadly refers to the business model of rapidly converting designs and trends into cheap and readily available clothing. While it鈥檚 been celebrated for making high fashion accessible to the masses, the model is also blamed for : One estimate suggests between 2000 and 2015, a period during which the Ellen MacArthur Foundation estimates a 36% decline in the number of times an item was worn before being thrown out. Every year, mountains of , where much of it ends up in landfills or on beaches.

The fast fashion industry does feel pressure to resolve some of these issues, says Berkley Rothmeier, a director at the consulting company BSR. 鈥淚s it hitting literally the bottom lines in terms of quarterly profits? I think we can look at financial information and know it isn鈥檛 in a significant way,鈥 Ms. Rothmeier says. 鈥淗owever, there鈥檚 more to it.鈥 It鈥檚 now the norm, she points out, for big-name fashion companies, including H&M and Zara, to track their climate footprints, set science-based targets for cutting emissions, ramp up reliance on clean energy, cut use of plastic packaging and water, find ways to more responsibly source raw materials, use more recycled textiles and .

罢丑别谤别鈥檚 , though: the business model itself, which anticipates consumers checking for and purchasing new clothing far more often than necessity would dictate. While there is mounting evidence that companies and shoppers are paying attention to how clothing is made and how to dispose of it, the boom in resale is the only indication of anyone interrogating the quantity of clothing currently produced.

Independent analyst Veronica Bates Kassatly says any progress on this front is hard to stand up against fast fashion鈥檚 simultaneous growth. 鈥湴粘蟊鸢疴檚 a lot of talk about these younger people wanting to shop more sustainably but when you look at the shopping patterns, there鈥檚 absolutely no evidence of this,鈥 she says, pointing to one culprit in particular: 鈥渢he rise and rise of Shein.鈥

A Chinese e-commerce giant that took fast fashion to a new level, Shein鈥檚 ascent is one of the biggest arguments against the idea that the model is suffering. The company is part of a new cohort of ultra-fast fashion retailers that largely exist online and grow their customer base by relying on social media influencers and 鈥 social videos that include itemized breakdowns of big orders. Shein says its approach to manufacturing allows for smaller inventories, which means less excess production. But there is no denying the company is putting massive amounts of cheap synthetic clothing out into the world. Many Shein shoppers are , the same group most likely to express concern about climate change.

Ms. Kassatly says Shein鈥檚 popularity with Gen Z may have to do with their believing the company is in fact acting sustainably 鈥 鈥渓ike, Shein has a sustainability report,鈥 she says. In that , released for the first time last year, the company hadn鈥檛 yet finished calculating its climate footprint. A few months later, Shein disclosed emissions totaling tons of carbon dioxide equivalent (CO2e) for 2021, inclusive of emissions stemming from use of its products; that鈥檚 less than H&M鈥檚 disclosed emissions of 7.8 million tons of CO2 in 2021.

Sheng Lu, an associate professor of fashion and apparel studies at the University of Delaware, says Shein is an example of 鈥渢he popularity of cheap products.鈥 But he also sees signs that sustainable shopping is gaining traction, including the boom in resale (which Shein . 鈥淲e need patience,鈥 Mr. Lu says. 鈥淲e need to create an environment that can really encourage companies, not just punish them, to do more to make their products sustainable.鈥

THE RISK OF INACTION
Perhaps the best way to understand how fast fashion companies think about a potential backlash is to look at how they talk about it 鈥 or don鈥檛 鈥 with investors and the public.

After endorsing the Financial Stability Board鈥檚 Task Force on Climate-Related Financial Disclosures (TCFD) in August 2018, H&M conducted a the following year, where it first identified shifting consumer preferences as both a business risk and an opportunity. In detailed climate disclosures shared last year with the nonprofit CDP, H&M went a step further: estimating how those preferences could impact its sales over the next three to 10 years using a range of hypothetical scenarios.

鈥淚f we assume a hypothetical 10% drop in our European markets and a 5% drop in our remaining markets, based on the higher awareness of climate change in Europe, that would mean lost sales of approximately SEK 16.6 billion,鈥 the company detailed in a high-end estimate. That translates to roughly $1.5 billion in lost sales. On the low end, H&M anticipated lost sales of SEK 6.6 billion ($630 million).

H&M also estimated the possible financial upside of catering to evolving climate-driven tastes: increased sales of SEK 2.6 to 8 billion, or $248 million to $764 million. The company posted revenue of $22.4 billion last year.

H&M spokesman I帽igo S谩enz Maestre emphasizes that those numbers are hypotheticals 鈥渢o explain different scenarios鈥 and 鈥渘ot [an] actual prognosis we are working with.鈥 He added that 鈥渃ustomers are more aware of the impact of the fashion industry and pay more attention to companies鈥 efforts to tackle their impact.鈥

In its own , Zara parent company Inditex calls the potential for consumers to strongly prefer more sustainable products an 鈥渁cute鈥 risk that could reduce earnings in the short and medium term. That鈥檚 assuming the world is actively rallying to mitigate climate pollution in line with the Paris Agreement; the company frames the risk as less urgent if the world is slower to respond. Inditex also identifies a 鈥渕inor鈥 reputational risk stemming from customers engaging in climate activism and souring on companies with carbon-intensive businesses. While Inditex doesn鈥檛 detail what such a hit could mean for sales, in its latest filing with CDP the company did find that shifting preferences could help sales 鈥 identifying it as a 鈧2.7 billion ($2.9 billion) opportunity. Inditex declined to comment.

H&M appears to be the only major fast fashion retailer to have assigned numbers to the risk of more climate-conscious consumers. 鈥淚t鈥檚 certainly not super common right now, at least externally, to see those,鈥 Ms. Rothmeier says. But that could change as more companies endorse the TCFD, and with more regulatory pressure, particularly in Europe. (Michael R. Bloomberg, the founder and majority shareholder of Bloomberg LP, parent company of Bloomberg News, is chair of the TCFD.)

Last year, the UK for large companies, based in part on the TCFD recommendations. The new requirements prompted Asos and Boohoo to conduct their first detailed climate analyses. Both companies are by the UK鈥檚 Competition and Markets Authority for possible greenwashing. In its , Asos identified 鈥渃hanging consumer preferences鈥 as a moderate risk and opportunity to the company in both the short term (2025) and medium term (2030). Meanwhile, Boohoo wrote in that 鈥渃onsumers may reduce consumption of fast fashion due to environmental concerns鈥 and noted it could take a reputational hit by not doing enough on environmental issues. Neither company responded to requests for comment.

In its 2022 CDP disclosures, Associated British Foods 鈥 parent company of Irish fast fashion retailer Primark 鈥 said that its reputation could take a hit from investors and customers if the company doesn鈥檛 do enough or is perceived to not be doing enough on climate. In response to questions from Bloomberg Green, ABF said the company believes its 鈥渃ommunication on climate change to be a 鈥榣ow risk鈥 because of our approach鈥 of regularly engaging with investors and others about its climate response.

Other private fast fashion retailers, including Fashion Nova and Forever 21, have yet to make any CDP disclosures, mention sustainability in their annual reports, or talk publicly about what more climate-conscious consumers could mean for business. Neither responded to questions from Bloomberg Green.

Shein, which is privately held but has been , also declined comment. In its sustainability report, the company noted that it is always looking 鈥渇or opportunities to support the causes [our customers] care about, from product design and material choice to product end-of-life, circularity and charitable giving.鈥 On its website, a spring sale features a belted romper for $5.98 and a kids鈥 denim jacket for $12. 鈥 Bloomberg
