The US online secondhand clothing resale platform ThredUp recently released its fifth annual impact report, detailing its ESG (environmental, social, and governance) strategy and progress from January 1 to December 31, 2025. The report shows that the company has cumulatively processed more than 261 million secondhand items since its founding, with about 90% of the inventory received in 2025 recirculated into wearing use through its own platform, thrift partners, or "rescue boxes," while the typical domestic resale rate for traditional charities is only about 20%.

In its "Resale-as-a-Service" business, ThredUp recirculated a total of 1.7 million secondhand items in 2025, further expanding the influence of its circular model through partnerships with leading brands. By the end of 2025, the platform had more than 1.7 million active buyers and over 60,000 brands for sale. The company claims that its secondhand trading activities have cumulatively helped reduce carbon dioxide emissions equivalent to 1.3 billion pounds, save 13.4 billion gallons of water and 2.5 billion kilowatt-hours of energy, while saving buyers about $9.4 billion in retail price differences.

ThredUp also emphasized the role it played in promoting the closure of the US "de minimis" loophole. The company has advocated for years for fixing this policy gap to curb the large influx of ultra-fast fashion goods into the US market duty-free. ThredUp CEO James Reinhart said that circularity is not just a side project outside the business, and that the company's growth and environmental impact are inseparable.

The company reiterated that it will continue to publish an impact report every year to ensure operational transparency and continuously measure its own environmental and social performance. This report also reflects the increasingly important position of the secondhand clothing industry in the global transition to sustainable fashion through policy advocacy and quantifiable environmental results.
