The round financial system – the theory of “reduce, reuse and recycle” – has lengthy been promoted as one strategy to the environmental disaster. As an alternative of the previous “take, make, use, throw away” type, it targets to stay fabrics in play for so long as conceivable.
In model, this implies going way past conventional restore conduct and buying groceries secondhand. It includes inventions reminiscent of clothes apartment platforms, fibre-to-fibre recycling, and AI gear that reduce waste in provide chains and kind textiles for recycling.
This feels like a win-win: much less waste, fewer uncooked fabrics used, and a lighter footprint on the earth. However actually, those inventions may just finally end up making issues worse.
In our fresh learn about, we discovered that inventions within the round financial system – particularly within the textiles and clothes trade – can cause what’s known as a “backfire rebound effect”. That is the place the manufacturing and intake of clothes rises, doubtlessly wiping out any environmental beneficial properties. It occurs when potency enhancements decrease prices and make merchandise appear extra sustainable, tempting shoppers to shop for extra.
The rebound impact is an index measuring how innovation impacts manufacturing – starting from beneath 0 (“super conservation”: the most efficient result for the surroundings) to above one (“backfire”: the worst), with a variety of results in between.
It’s no longer a brand new thought. In 1865, British economist William Stanley Jevons noticed that enhancements in coal potency in reality resulted in extra coal being burned. Lately, the similar dynamics can happen in model.
Recycled clothes, advertised as eco-friendly, would possibly tempt other people to shop for extra. And if model manufacturers then scale up – at house or in another country – the unfavorable environmental affect is amplified, wiping out lots of the beneficial properties from recycling.
Till now, no research had quantified the rebound impact for the worldwide textile trade. Clothes and textiles are extensively held to be the sector’s second-most polluting sector after power, eating round 20% of the sector’s water once a year, emitting 1.7 billion tonnes of CO₂ every year (about 10% of world emissions), and producing 92 million tonnes of waste every yr. Lower than 1% of this waste is recycled into new clothes.

With annual world manufacturing of recent textiles projected to climb to 160 million tonnes by way of 2030 (from 124 million tonnes in 2023), the velocity of this progress approach there’s a transparent want for extra recycling and reuse. But our analysis means that environmental inventions may just in reality result in larger ranges of world textile intake.
In particular, we discovered a world moderate backfire impact of one.6 – a strikingly prime determine. Which means that for each 1% acquire in environmental textile innovation, there shall be an building up in new textile manufacturing of 0.6%.
We will be able to call to mind it with regards to automobiles that transform extra fuel-efficient: as an alternative of saving petrol, other people would possibly power extra. In the similar manner, reasonably than easing power on the earth, innovation in textiles is fuelling extra manufacturing and hurt. What we truly want is a rebound impact beneath 1 (a “partial rebound”) – or higher nonetheless, beneath 0 (tremendous conservation).
What reasons this particular rebound in textiles?
When an effective recycling innovation is presented, manufacturing prices drop, very similar to the instance of the fuel-efficient automobiles. Shoppers, drawn by way of decrease costs and the ethical attraction of “sustainable” merchandise, building up their purchases. Companies see alternatives to extend into new markets. Quickly, the beneficial properties from the innovation are beaten by way of emerging call for, leaving the planet worse off.
This doesn’t imply round financial system methods for model must be deserted – however they want guardrails. In our simulations, a Pigouvian tax (a tax on destructive behaviour) was once efficient in lowering the rebound impact.
The better the potency beneficial properties from round inventions, the upper the tax required to forestall unsustainable intake. For textiles, we discovered {that a} 10% potency acquire from round innovation – reminiscent of fibre-to-fibre recycling or AI sorting – calls for a minimal uniform tax of one.25% on manufacturing to forestall backfire (complete rebound). A 2.5% tax may just scale back the rebound to manageable ranges (partial rebound).
Use of taxes to scale back rebound impact of environmental textile inventions
More potent round inventions want upper taxes to forestall rebound harms.
Creator supplied, no reuse.
Different conventional coverage gear may just succeed in an identical effects, together with manufacturing caps on new garments, incentives for longer lifespans for merchandise, and measures to inspire essentially sustainable intake.
And as the rebound impact isn’t uniform the world over, such insurance policies require each world coordination and measures which can be particular to particular person areas.
For instance, in Bangladesh, the place textiles account for greater than 80% of exports and make use of tens of millions of other people, blunt curbs on speedy model may just devastate livelihoods. But it’s call for from rich international locations for inexpensive clothes that fuels this dependence. Insurance policies should subsequently stability world environmental targets with native financial realities.
However the problem is going deeper – proper to the stress between a growth-driven financial gadget and the planet’s limits. Degrowth concept (the debatable however an increasing number of mentioned concept that populations may just voluntarily curb manufacturing and intake) asks whether or not true sustainability is conceivable if economies stay depending on expanding intake.
Behavioural exchange is a very powerful – this implies embracing minimalism, reusing extra, and purchasing simplest what in reality provides price. Within the model international, this is able to imply campaigns that advertise repairing garments and chopping again on intake, sponsored by way of insurance policies that information shoppers in opposition to those extra sustainable conduct.
Actual-life examples exist already. France has a restore fund that deductions a part of the price of mending garments. The Waste and Assets Motion Programme works in the United Kingdom, Europe and Australia as a public–non-public partnership to chop waste around the model sector. And schemes just like the Higher Cotton Initiative, Cascale and Model Pact purpose to shift manufacturing in opposition to extra sustainable practices.
Our learn about is the primary to quantify the rebound impact of round financial system innovation in textiles at each world and regional scales. Its findings recommend a nuanced fact: circularity can assist, but with out further adjustments it dangers accelerating the issues it was once supposed to unravel.
We imagine that measuring this rebound impact is essential if insurance policies are to ship in observe. The craze trade must again its sustainability guarantees with proof, no longer simply excellent intentions.
