How Luxury Fashion Brands Are Rewriting Responsibility

When Stella McCartney launched her eponymous, Gucci-backed fashion label in Paris in 2001, she did something no serious luxury brand had tried before: banning leather, fur and skins altogether. At the time it was a revolutionary moment in high-end fashion that put ethics, transparency and responsibility ahead of pure profit.

Unsurprisingly, the move brought as much scepticism as it did interest, with many in the industry viewing McCartney’s approach as naive or commercially suicidal. She even recalls being “kind of ridiculed” and told she would never build an accessories business without leather.

Two decades later, the pace at which the rest of the luxury fashion industry is playing catch up makes that pioneering moment look less like idealism and more like a sustainable blueprint. And there is good reason for urgency.

Luxury’s heavyweight impact

Unlike top-tier fashion’s catwalks, the numbers linked to the industry are far from glamorous. The fashion and textiles sector is estimated to account for between 2-8% of global greenhouse gas emissions, alongside around 9% of the microplastic pollution reaching oceans each year.

McKinsey puts the industry’s 2018 emissions at 2.1bn tonnes of CO2 equivalent, roughly 4% of the global total, with most of that impact sitting upstream in fibre, fabric and finishing. 

Luxury is a small slice of that volume but a heavyweight in terms of high-impact materials.

Recent research led by New York and Cornell Universities calculates that animal-derived materials such as leather, wool and cashmere – staples for most luxury fashion houses – make up only 3.8% of apparel by volume yet generate around 75% of fashion’s methane emissions, equivalent to 8.3m tonnes a year, and nearly four times the annual methane footprint of France. 

The good news is it’s a corner of the market well positioned to respond. Luxury operates with high margins, low volumes and a consumer base that believes in ‘buying less, but buying better’.

That gives room for investment in alternative materials, regenerative agriculture and supply-chain traceability that budget fashion cannot always easily match. It’s also why industry bodies speak of an “unprecedented opportunity” for luxury to set the pace on end-to-end sustainability. 

Sustainability as long-term value

The cultural shift has been gradual but purposeful, with other brands taking McCartney’s mantle and running with it.

In the early 2010s Kering piloted an Environmental Profit & Loss account with Puma, often cited as one of the first serious attempts by a luxury group to price natural capital, while the likes of Chanel, Gucci, Giorgio Armani and more moved to fur-free products. 

In 2019, Kering Chief Executive François-Henri Pinault launched the Fashion Pact at the G7 in Biarritz, bringing together dozens of brands under shared commitments on climate, biodiversity and oceans.

Most recently the group, consisting of brands including Chanel, Moncler Group, Prada Group and Hermès, launched the European Accelerator initiative designed to improve supplier data and drive more sustainable supply chains. 

For fashion’s biggest businesses, pressure is intensifying from every side. In Brussels, the EU Strategy for Sustainable and Circular Textiles, launched in early 2022, is now being translated into binding rules on eco-design, recycled content and more, pushing the compliance agenda. 

Investors increasingly treat environmental and social performance as a measure of operational discipline and long-term value, while consumer habits are reshaping the conversation.

A 2023 survey of European luxury shoppers found that 77% consider sustainability an important factor in their purchases and 51% are prepared to pay up to 10% more for products with lower environmental impact in production or delivery.

Buying habits are shifting too. The global second hand fashion and luxury market is rapidly becoming big business, forecast to reach as much as US$360bn by 2030 and growing three times the rate of the primary market. The test for luxury items increasingly lies in their durability, repairability and resale value. 

Against that backdrop, the world’s leading fashion houses have little choice but to place sustainability at the heart of their growth strategy, reshaping what modern luxury looks like.
