It’s tender. It is vegan. It looks just like leather.
It’s also made from fossil fuels.
An explosion in the use of low-cost, petroleum-based mostly components has transformed the fashion sector, aided by the profitable rebranding of artificial supplies these kinds of as plastic leather-based (at the time significantly less flatteringly referred to as “pleather”) into hip solutions these kinds of as “vegan leather,” a internet marketing masterstroke meant to recommend environmental value.
Underlying that effort and hard work has been an influential rating program examining the environmental impact of all types of materials and products. Named the Higg Index, the ranking method was released in 2011 by some of the world’s biggest style manufacturers and suppliers, led by Walmart and Patagonia, to measure and eventually support shrink the brands’ environmental footprints by slicing down on the drinking water utilized to produce the clothing and footwear they offer, for instance, or by reining in their use of unsafe chemical compounds.
But the Higg Index also strongly favours artificial components designed from fossil fuels above all-natural types these types of as cotton, wool and leather. Now, these scores are coming underneath fire from unbiased authorities as properly as associates from pure-fiber industries who say the Higg Index is currently being utilised to portray the increasing use of synthetics use as environmentally attractive irrespective of concerns around synthetics’ environmental toll.

“The index is justifying the decisions vogue firms are creating by portraying these synthetics as the most sustainable alternative,” explained Veronica Bates Kassatly, a trend field analyst and critic of the industry’s sustainability promises. “They’re stating: You can still shop till you drop, for the reason that every little thing is now so sustainably sourced.”
The Sustainable Clothing Coalition, which operates the index and counts between its associates pretty much 150 brands, which includes H&M and Nike, as effectively as retail giants this sort of as Amazon and Concentrate on, explained the index utilizes information that is scientifically and externally reviewed.
“This is many years of get the job done to compile and set jointly the finest accessible most up-to-day info,” stated Jeremy Lardeau, vice president of the Higg Index at the clothing coalition. “We’re not actively pushing for the synthetic figures to be very low. We’re just amassing the data in a person put.”
Critics counter that some of the details underpinning the index will come from research that was funded by the synthetics market that has not been completely opened up to unbiased evaluation. Other scientific tests incorporated into the Higg Index are in some cases comparatively narrow in scope, increasing thoughts about their wide, industrywide applicability.
The index fees polyester as one of the world’s most sustainable materials, for instance, utilizing info on European polyester manufacturing offered by a plastics-field group, while most of the world’s polyester is designed in Asia, generally using a dirtier electricity grid and less than significantly less stringent environmental procedures. The Higg ranking for elastane, also recognised as Lycra or spandex, attracts on a examine by what was at the time the world’s largest elastane producer, Invista, a subsidiary of conglomerate Koch Industries. (Invista marketed its Lycra organization in 2019.)
The Higg Index itself was born a 10 years or so back amid a climbing emphasis among shoppers on sustainability, environmental and animal-welfare considerations. It coincided with developments in synthetic-based fabrics that were being not only affordable but had new functions that buyers craved, these as enhanced elasticity or improvements in the potential to wick away perspiration.
Lots of of the garment manufacturers that sit on the board of the team that oversees the index financial gain from two style megatrends that specifically benefited from advances in synthetics these as these: rapidly style and athleisure. Speedy manner big H&M, for occasion, displays what it phone calls Higg-based mostly sustainability profiles alongside some of its merchandise.
“Higg’s customers, a large amount of them are fast vogue brands, and they all use predominantly polyester. So it favors them to get polyester a greater ranking,” claimed Brett Mathews, main editor of Attire Insider, an sector-targeted publication dependent in London. But the data used was “very lousy,” he explained, and “the internet consequence is that the genuine Higg rating, which states this fiber is extra sustainable than that just one, is deceptive to customers.”

The Sustainable Apparel Coalition mentioned firm data was precise and in depth, and experienced been gathered in line with business criteria. Any gap in between European and Chinese polyester production would be modest in comparison with other differences in manufacturing the textiles, this sort of as the knitting or weaving course of action, it claimed.
H&M, which sits on the coalition board, claimed the index was primarily based on “standardised and confirmed third-occasion details,” and that the software was currently being “continuously created and enhanced.” Walmart explained the Higg Index was not the only device it made use of to boost the sustainability of its clothing, and that it ongoing to assess the index’s capabilities. Invista did not react to a request for comment.
The Higg Index is on its way to getting a de facto worldwide standard. In Europe, policymakers this calendar year are set to lay out regulations on how models should back again up their environmental claims, and in New York, a bill seeks to maintain fashion manufacturers accountable for their role in local climate change. Trend-sector officials have reported the Higg Index could be employed as a benchmark in the two.
The trend market has extended been under pressure to deal with the environmental consequences of its goods and methods. The marketplace is responsible for as much as 8% of the world’s emissions of planet-warming carbon dioxide, the United Nations estimates, a lot more than all international flights and maritime shipping put together.
Organic materials, these as cotton, have their personal environmental prices, of program. Cotton and silk cultivation is h2o-intensive and can contain hefty pesticide use. Leather can arrive from well-managed ranches, or it can be tied to functions that are really damaging to the natural environment. Past calendar year, a New York Periods investigation showed how leather-based from cattle connected to deforestation in the Amazon was creating its way to the United States to be made use of in vehicle seats.
The generation of polyester and other supplies has tripled given that 2000, to nearly 60 million tons a calendar year, according to the Textile Exchange, an sector group. Silk and wool have declined more than the exact same time period, and cotton has risen extra moderately.
Producers of organic fibers say the Higg Index has portrayed that change as positive for the setting based on questionable details. Silk’s unfavorable score in the index, for illustration, attracts on a 2014 study by Oxford-dependent researchers of 100 silk farmers who count on irrigation in a solitary condition in India.
That study’s lead researcher, Miguel Astudillo, mentioned he hadn’t known until finally just lately that his operate experienced been applied by the Higg Index. He explained his study of Indian silk, which is mainly made use of domestically, was not consultant of international output. “If they go through the short article and the final results, they’d know it is a stretch to use it for evaluating silk in normal,” Astudillo mentioned.
The Worldwide Sericulture Fee, which signifies 21 silk-generating countries, final calendar year filed a grievance with the Federal Trade Commission accusing the Higg rankings of “creating significant damage to the pure fiber industry” and calling on the index to carry out a broader examine of international manufacturing procedures.
“They’re stating silk is 30 situations worse than artificial goods. Can any person definitely believe that?” reported Dileep Kumar of the International Sericulture Commission.
In 2020, leather-based-field teams from all over the planet also named on the Sustainable Clothing Coalition to suspend its weak rating for leather, which the field reported was dependent on “out-of-date, unrepresentative, inaccurate and incomplete data.”
The rise of vegan leather — which is typically produced from polyurethane, a form of plastic that has a more favorable Higg score — has introduced unintended penalties, industry officials say. Even as leather is replaced by synthetics, Us residents are even now ingesting heaps of beef — which usually means the hides from individuals slaughtered cattle have nowhere to go. In 2020, a record 5 million hides, or about 15% of all offered, went to landfills, in accordance to the U.S. Hide, Pores and skin and Leather Affiliation, a Washington-primarily based trade group.
“They’re throwing the hides in the offal barrels out again,” mentioned Ron Meek, a former meat processor who has been serving to lesser vegetation temperature the downturn in leather demand from customers.
This 12 months, the sole agent of an environment team on the Sustainable Clothing Coalition board of administrators resigned, citing the organisation’s deficiency of development on environmental and local weather policies, and hasn’t been changed.
“Their tactic has been shrouded in a large amount of secrecy. It is not a transparent technique,” claimed the previous board member, Linda Greer, who now advises China’s Institute for Public and Environmental Affairs. “This business, perhaps more so than any other sector, is really significant on converse, pretty huge on the future remarkable factor — virtually as if it’s a style clearly show, the season’s hottest.
In response to the problems, the attire coalition has de-emphasised direct comparisons across materials and mentioned it is serving to companies to make extra sustainable decisions within fabrics, and to occur up with unique product-based mostly scores that just take into account factory practices and other variables. It also claimed it would welcome the submission of more information from pure fiber industries.
However, some professionals question no matter whether the Higg accurately demonstrates other elements, together with emissions of world-warming methane from the fossil fuels from which plastics are derived, the quantity of nonbiodegradable plastic that finishes up in landfills or incinerators, and the microplastics lose by materials that have now been detected by researchers in the world’s oceans.
The clothing coalition said this was an concern it was searching for to integrate once better knowledge was accessible.
In all, experts say, relying on scientific tests with various parameters and assumptions is challenging. A 2019 report by the Exploration Institutes of Sweden concluded that variances among producers could be considerably much larger than dissimilarities in between fiber sorts.
“The devil’s in the information,” reported Sangwon Suh, an skilled in life-cycle assessments at the Bren Faculty of Environmental Science and Management at the College of California. “It’s tough to make generalisations. Is the cotton rain-fed, or does it use irrigation or groundwater? Are the petroleum-primarily based artificial components getting produced in countries with rigorous polices?”
For people, all these variables make it difficult to generalise about irrespective of whether all-natural or artificial elements are the far more environmentally helpful preference, or to assess claims built by clothes manufacturers. Gurus say one particular of the couple positive strategies to minimise environmental impression is basically to get fewer, lengthier-lasting pieces.
The Sustainable Attire Coalition helps make the Higg Index scores offered to the community, but full access to the fundamental facts is restricted to businesses that pay back a charge.
Providers can also pay back a charge to submit new data to the coalition and obtain corporation-unique scores.
Final yr, for case in point, the Higg Index claimed it had up-to-date the ranking for leather-based from JBS, the world’s most significant meatpacker and a single of the companies that the Instances investigation final year uncovered was sourcing cows connected to Amazon deforestation. The new JBS-specific assessment prices leather-based produced by JBS as among the world’s most sustainable.
JBS claimed it had submitted a new examine to accurate the apparel coalition’s “misleading analyses” on leather-based. “JBS also intends to contribute to elevate the quality of technical facts out there on leather, benefiting the overall sector,” the enterprise mentioned.
Gregory Norris, who teaches life-cycle assessment at the Harvard Faculty of General public Health and who carried out a overview of the Higg Index methodology in 2016, claimed numerous of the critics’ problems have been legitimate. But the index however represented “a incredibly useful human body of get the job done,” he claimed. “They could have waited, but to their credit history, they dug in and they constructed some thing with today’s knowledge,” he claimed.
Still, there ended up enhancements that could be manufactured, he said. For illustration, market info could be periodically verified with impartial place checks. “There’s facts-shortage issue that actually wants to be solved,” he explained.
