Natural fibers like wool, cotton, alpaca, and flax linen can be grown and raised in ways that maximize the drawdown of carbon from the atmosphere to help restore ecosystem health and stabilize our climate.

Fibershed’s Climate Beneficial™ Verification program and label supports farmers and ranchers in landscape level stewardship that centers the work to build healthy soil. We focus on engaging producers and developing financial and technical support to enhance the drawdown of carbon from the atmosphere. By connecting fiber producers with designers and markets that value ecosystem services, we can grow materials and supply chains rooted in verified practices that:

  • Increase Soil Organic Carbon levels
  • Enhance biodiversity by providing habitat for pollinators, birds, and many species
  • Improve the water-holding capacity of the soil
  • Restore healthy ecosystems, from the soil microbiome to nutrient cycles
  • Provide measurable climate benefits, quantified by open-source data tools

Choosing Climate Beneficial verified fiber connects your garment or durable good directly to practices that regenerate soil carbon, and so much more.

How Our Practice-Based Verification Works:
Climate Beneficial fiber production regenerates working landscapes through the implementation of carbon farming. Fibershed designed the Climate Beneficial Verification to support and increase adoption of carbon farming practices on fiber and dye producing landscapes.

  • We work directly with producers in Northern California to provide education and support for adopting practices
  • We verify carbon farming practices every year on participating producer landscapes
  • We partner with agriculture experts to develop Carbon Farm Plans for participating producers
  • We develop markets for Climate Beneficial Verified fiber by sharing educational information with the public, with fashion and textile designers and brands, and by connecting producers to buyers
  • We expand support for producers to activate carbon farming practices by working with policymakers, connecting producers to public funding, and raising and issuing funds directly through the Carbon Farm Seed Fund
  • We focus our verification process within the Northern California Fibershed, and we collaborate with peer communities through our Fibershed Affiliate Network to develop place-based verification systems

California produces nearly 3 Million pounds of wool per year, thanks to sheep grazing upon the vegetation of rangeland, pasture, perennial and annual cropland systems. From large ranches to backyard homesteads, Climate Beneficial™ Wool has engaged over 55 producers in the Northern California Fibershed network. Wool production pairs well with time-honored landscape management practices that have been scientifically modelled to measure carbon drawdown: click here to learn more and connect with producers or products.


Flowering cotton fields are part of an annual agricultural cycle of food and fiber production in California. With more than 250 Million pounds of white cotton produced annually in the Golden State, as well as naturally colored Colorganic® cotton, there is a major opportunity to regenerate soil and water health. Fibershed is currently partnering with farmers and researchers to understand how carbon farming practices can be incorporated into cotton landscapes: click here to learn more.


Soft and luxurious Alpaca fiber is most frequently raised on small to mid-scale farms in California. Northern California Fibershed Producers who are participating in our Climate Beneficial program can be found by visiting our producer directory page and exploring the filters on the member map.

Fibershed Affiliate Network member NY Textile Lab has developed a local Climate Beneficial verification for the Hudson Valley of New York State, with several participating Alpaca producers.

Flax & Hemp

Bast fibers including flax and hemp produce strong, breathable fabrics from sturdy plants. The Chico Flax Project is piloting Climate Beneficial Transitional verified flax by incorporating carbon farming practices into their demonstration farm in the Northern California Fibershed region.

Fibershed currently works with partner organizations in the Southwest and Southeastern United States to trial and document hemp production and processing possibilities: click here to learn more about hemp research.
