Explore 27 sustainable fashion brands who are lowering carbon emissions, sourcing eco-friendly fibers, and considering their impact on people and planet.

What is the definition of Sustainable Fashion?

Sustainable fashion refers to efforts by companies to produce clothing and apparel in ways that address environmental, labor, social and/or community priorities.

There is no widely accepted definition for “sustainable fashion.”

Various textile and clothing companies and nonprofits utilize the banner of sustainable fashion to reflect a spectrum of efforts to advance social, labor, and environmental best practices and innovations.

Clothing and textiles sold under the banner of sustainable fashion may incorporate efforts to:

  • reduce carbon emissions, achieve net-zero emissions or be “Climate Positive,”
  • address packaging waste,
  • source sustainably-produced, organic, recycled or deadstock fibers and materials,
  • provide for end-of-life recycling or disposal of their products, or
  • adhere to fair trade or other worker-centric business practices.

If you really want to understand what a particular company means when it says it produces sustainable fashion or clothing, you have to get under the hood of its practices. (You can also look to various nonprofit standard-setting, audit and certification bodies like B Corporations, Fair Trade Certification and Climate Neutral Certification.)

Sustainable Fashion Brands

What are good examples of sustainable fashion brands? Sustainable fashion brands on this list like Everlane, Cotopaxi, Outerknown, Allbirds, Pact and Nisolo are engaged in various efforts to reduce the environmental impact of clothing and support sustainable supply chains and fair labor practices.

Everlane

Clothing startup Everlane pledges to build a more ethical, sustainable and “radically” transparent supply chain for its lineup of smart casual and everyday wardrobe basics for women and men.

Among other initiatives, this sustainable fashion brand has committed to eliminate the use of virgin plastics by 2021, to use only certified organic cotton by 2023, and to use recycled synthetic materials. The company also lists out its factories and pricing structure to improve visibility into its partners and practices.

Everlane has become one of my family’s go-to destinations for basics like t-shirts, chinos, athleisure leggings and cashmere sweaters and is excellent example of the kind of stylish clothing company helping men and women dress sharp in the digital age.

Try Everlane’s jumpsuits and tee shirt dresses for women, a range of cashmere and merino sweaters for men or extensive selection of denim.

Allbirds

Allbirds, which makes attractive minimalist sneakers for women and men, pledges to “measure, reduce and offset” its carbon emissions and provide transparency along its sustainability journey.

A certified B-Corporation, this sustainable fashion brand has committed to reduce its emissions, source low-carbon materials, rely on ocean shipping rather than air, purchase in renewable energy and committing to energy efficiency in its operations.

Allbirds is one of several sustainable fashion options for minimalist knit sneakers for men and women.

Standards and certifications for sustainable retail

One way to gauge a company’s sustainability practices is to see if they adhere to various certifications, standards and metrics.

There are a number of private sector and nonprofit efforts to evaluate companies against sustainability, climate and labor metrics.

Here are several to watch for:

Certified B Corporations

Companies can opt to apply for a private certification from B Labs, which evaluates and scores companies based on a set of social and environmental criteria.

According to B Labs:

Certified B Corporations are a new kind of business that balances purpose and profit. They are legally required to consider the impact of their decisions on their workers, customers, suppliers, community, and the environment. This is a community of leaders, driving a global movement of people using business as a force for good.

Certified B Corporation

Companies receive a numerical score from B Labs. A minimum verified score of 80 is required across all sustainability areas identified by B Labs to be certified. Supposedly, a higher the overall score is meant to convey adherence to B Labs’ performance and certification requirements.
