As William Reed’s annual Sustainable September campaign comes to a close, here are the must-read data analysis, interviews, news and insight into how retailers and consumers are responding to the climate crisis.

Secondhand is first choice…for some

Vinted has become a dominant presence in the UK fashion scene, with Retail Week revealing earlier this year that the brand had become the country’s third-largest fashion retailer by number of customers.

Exclusive data from brand tracking platform Tracksuit revealed that high-income households are the most likely to shop secondhand, with over half of households earning over £80,000 have used Vinted, compared with 34% of those earning under £20,000.

In her column, Oxfam retail and trading director Lorna Fallon writes: “The secondhand revolution is not simply changing how people shop, it is creating new opportunities for retailers, partners and charities alike.”

Holland & Barrett gets more transparent

The health and beauty high street retailer published its first-ever sustainability report this year for its staff, suppliers and customers to understand the steps it’s making on becoming more green.

Its sustainability and impact director Jessica Long spoke to Retail Week about where the retailer is at in terms of Scope 3 emissions, net-zero ambitions, responsible sourcing, what is going well, and what can be improved. “We believe you can’t be well on a sick planet,” she says.

Fashion goes Dutch

We went behind-the-scenes at Amsterdam-based clothing brand Martan, which is creating luxury fashion from discarded textile waste from the hotel industry (think used tablecloths and bed sheets). 

The Dutch capital has ambitions to halve its use of new raw materials by 2030, and to be fully circular by 2050, which would make it the first city in the world to build a circular economy.

One of the most applauded circularity initiatives to come out of Amsterdam is the United Repair Centre, a social enterprise which partners with brands to repair clothing sent in by customers.

The food security challenge

Food, drink and ingredient manufacturing businesses are investing in standard operational technologies wrongly believing they will help them deliver more climate-resilient businesses.

According to a new report by Lumina Intelligence, 51% of food, drink and ingredient manufacturing leaders said that investment in robotics and automation now will deliver the best results in improving their business’ climate resilience.

Nearly half of the 250 respondents surveyed for the Climate-Smart Resilience report by Lumina said investment in digital supply chain platforms would have the greatest impact, while 43% said they believe artificial intelligence would deliver the best outcomes.

Retailers need to talk the talk

This could be the first year since 2017 that energy costs have been mentioned more times in UK retailers’ earnings calls than sustainability, according to AlphaSense data

About 41% of retailers’ earnings calls in 2026 mention energy costs, against 22% referring to environmental sustainability, according to data analysed by Retail Week.
