By shopping and selling on Poshmark, we are inherently creating a more sustainable future. By extending the life of items, our community is actively keeping millions of items in circulation every day to help reduce fashion’s environmental impact.

Our community has kept 350M+ items in circulation and out of landfills, reducing the climate impact in the fashion industry.
Product Features
At Poshmark, we continue to make changes and introduce new features into our product to help shop and sell sustainably—so you don't have to sacrifice style or your wallet.
Reposh
This unique feature allows you to list your past Poshmark purchases with a single click. Over 8M+ items have been reposhed, further extending their life, and keeping them out of landfills.
Posh Parties
We curate and promote sustainable brands and products through Posh Parties—virtual parties where sellers and shoppers attend in real time. In partnership with a sustainability expert, we developed criteria for brands being featured in these parties, we look at:
- The % of all materials used in a brand's products and sustainable sources
- Their suppliers and energy consumption
- Their commitment to address climate change and packaging materials
Packaging Tips
We recommend our sellers take the initiative to incorporate sustainable packaging practices with each sale they make. Even for the casual seller, these easy tips can have a long-lasting impact:
Creating a Movement

In 2022, Poshmark introduced the first-ever holiday dedicated to supporting secondhand sellers, circular fashion, and the planet. An annual event that happens the Sunday after Thanksgiving during the biggest shopping weekend of the year.
Earth Month
This Earth Month, we're turning up the fun with feel-good fashion, live giveaways, and a University of Arizona campus takeover with Reclectic. Discover eco-conscious sellers, win goodies from brands like Baggu and Cuyana, and celebrate the power of secondhand. Head to our socials to join the fun and learn more!

Partnerships

Veritree
Since 2021, Poshmark has partnered with Veritree to plant over 60,000 trees, supporting global reforestation. This initiative helps restore vital landscapes, capture CO2, and provide economic benefits to local communities, reflecting our commitment to sustainability and climate action.

USPS
Since 2014, Poshmark and USPS have partnered to promote sustainability in fashion resale through PoshPost, using eco-friendly shipping to support a circular economy. This collaboration reduces waste, extends item lifecycles, and lowers demand for new production. In May 2022, Poshmark received the WestPac Innovation and Growth Award from USPS for driving growth and adopting best practices.

Partnership Opportunities
We are always looking to expand our network of like-minded partners who share our vision for sustainability and innovation. If you are interested in collaborating with Poshmark to drive positive environmental and economic impact, we encourage you to reach out to brands@poshmark.com
