The Nuvinty Index, Q3 2026: 10 Sustainability Moves Worth Knowing
Reviewed by the Nuvinty editorial team · Published
Ten moves by luxury brands, retailers and resale platforms that make products last longer or make their impact easier to check: repair at scale, brand-run buy-back, certified pre-owned, traceable materials and unusually candid reporting. Each one is described from the company's own announcement, with the caveats that matter.
Announced between April and early October 2026 (this first edition reaches back to April). An editorial selection, not a rating: inclusion means a move is notable, not that the company is sustainable overall. How we choose.
1. Best repair programme
Louis Vuitton: Care & Repair at the centre of the Monogram's 130th year
Repair · 1 Sep 2026
Louis Vuitton made repair a headline of its Monogram anniversary, with repair pop-ups through the year including one in London in April. Parent group LVMH says the house runs 12 repair centres handling around 500,000 products a year and plans to extend repair to every product category by 2030. Group-wide, LVMH says repair and refill brought in nearly €500m in 2025.
Worth knowing: An existing service given a bigger push rather than a new launch; the 2030 goal is a target, and repair volumes differ slightly between sources.

2. Best brand-run buy-back
Mulberry: Mulberry Exchange pre-loved sales up 46%
Resale · 22 Jul 2026
Mulberry's full-year results reported pre-loved sales through Mulberry Exchange up 46%. Customers trade in old Mulberry bags for credit, and Mulberry authenticates and restores them for resale, alongside a long-running lifetime repair service.
Worth knowing: Self-reported, and the results give a growth rate rather than a sales value.
3. Best transparency move
Pandora: A carbon footprint label on every lab-grown diamond
Transparency · 6 May 2026
Pandora now shows a carbon footprint for each lab-grown diamond on its site, from raw materials to polished stone, calculated to the ISO 14067 standard with limited assurance from EY. It published the methodology alongside it. The stones are set in recycled silver and gold.
Worth knowing: The figure stops at the polished stone, and Pandora's comparison with mined diamonds relies on an industry-funded 2019 study.
4. Most candid report
Selfridges: Reselfridges Report 2025
Transparency · 26 May 2026
Selfridges reported circular revenue (pre-loved, repair, rental and refill) of £17.6m for 2025, up 27%, with pre-loved making up about 70% of it. Unusually, it also said plainly that it will miss its 2030 target for circular transactions, paused rental and reset its strategy.
Worth knowing: Self-reported, with no independent assurance found. A goal reset rather than a goal met.
5. Biggest certified pre-owned programme
Rolex: Certified Pre-Owned sales double
Resale · 29 Jul 2026
Rolex's Certified Pre-Owned programme, in which authorised retailers sell checked pre-owned Rolex with a new two-year guarantee, roughly doubled its sales in the first half of 2026 according to market tracker EveryWatch, overtaking the trade in unworn watches for the first time.
Worth knowing: The sales figures are a third-party estimate; Rolex does not publish them. Certified watches sell at a premium to the same uncertified watch.
6. Diamond traceability
Tiffany & Co.: 2025 Sustainability Report
Materials · May 2026
Tiffany reports that 99.99% of its newly sourced, individually registered diamonds are traced to a known mine or a supplier's set of approved mines, and that all its diamond suppliers are certified by the Responsible Jewellery Council.
Worth knowing: "A set of approved mines" is not always a single mine, and the figure covers individually registered stones only.
7. Decade-long progress report
Kering: 2016–2025 Impact Report
Transparency · 4 Jun 2026
Gucci and Saint Laurent's parent Kering published a ten-year impact report: 97% traceability of key raw materials, a reported 34% absolute cut in greenhouse gas emissions, and new targets for regenerative and alternative materials by 2035.
Worth knowing: Measured against Kering's own definitions, and some original targets were changed over the decade.
8. Pre-owned goes mainstream
Watches of Switzerland Group: Pre-owned becomes its second-largest category
Resale · 14 Jul 2026
The owner of Goldsmiths, Mappin & Webb and Watches of Switzerland reported pre-owned sales up 22%, now more than 8% of its luxury watch revenue (under 2% in 2019), with Rolex Certified Pre-Owned in 30 UK showrooms and plans to offer it in all of them.
Worth knowing: A commercial result reported by the company, not a measured environmental impact.
9. Interesting materials launch
Mejuri: Salmon Gold with traceable Montana sapphires
Materials · 14 Sep 2026
Mejuri's third Salmon Gold collection uses gold recovered from old mine workings in Alaska and the Yukon as part of river-habitat restoration, paired for the first time with sapphires sourced only in Montana.
Worth knowing: A small limited run; the gold volume isn't stated and verification comes from the programme partner rather than an independent body.
10. Best vintage restoration
Jaeger-LeCoultre: The Collectibles VI, shown in London
Resale · 15 Jun 2026
Jaeger-LeCoultre sourced, restored and certified twelve vintage watches, mostly Reversos made between 1931 and 2003, in its own restoration workshop, and showed them at its Bond Street boutique before sale.
Worth knowing: Very small volume, and close to heritage marketing; included as an example of a maker standing behind its old watches.
