The conversation around sustainability has evolved, moving beyond broad pledges to a clear industry-wide focus on proven, measurable impacts. This shift is accelerated by changing global regulations that require brands and retailers to provide data and transparency for their entire supply chain, including complex Scope 3 emissions.
Answering this call, the U.S. Cotton Trust Protocol has released its 2024/25 Annual Report, a landmark five-year analysis. The Trust Protocol is the first sustainable cotton fiber program to offer such a comprehensive data set, providing powerful, third-party verified evidence of the program’s effectiveness. The results confirm the program’s more than 1,500 grower members have made meaningful environmental gains, cementing their position as leaders in sustainable cotton production and providing brands, retailers and the fashion industry as a whole with the credible data and verifiable proof they need to confidently report sustainability goals.

Five Years of Measurable Impact: Exceeding Ambitious Sustainability Goals
Trust Protocol growers have met or exceeded five of the six ambitious 2025 National Goals for Continuous Improvement, a full year ahead of schedule for some metrics. Compared to a 2015 baseline, the aggregated field-level data from five years of operations delivers measurable improvements in efficiency, resilience and environmental outcomes at scale.
The data shows a 15 percent improvement in land use efficiency, reaching the 2025 goal a year early. This demonstrates a reduction in the land needed to grow one pound of cotton, a testament to the efficiency gains from the program’s practices. Water use efficiency saw an 87 percent improvement, despite widespread drought conditions, with growers producing the same amount of cotton using 47 percent less irrigation water. The program also recorded a 28 percent reduction in energy use and an impressive 89 percent reduction in soil loss, bringing erosion levels well below USDA thresholds and preserving vital topsoil for future generations.
Additionally, there has been a meaningful achievement in soil health, with growers now actively building healthier soils that sequester carbon. Despite an ambitious 2025 target, growers have already achieved a 25 percent reduction in greenhouse gas (GHG) emissions by optimizing nitrogen use and adopting smarter irrigation technologies. These environmental gains were achieved without sacrificing productivity; in fact, Protocol growers produce 20 percent more cotton per acre than the U.S. average, proving that sustainability and efficiency can go hand in hand.
The Data-Driven Answer to a New Era of Regulation
These metrics are more than a report card; they are a critical tool for brands and retailers navigating an increasingly complex global regulatory landscape. With the implementation of new rules like the EU’s Corporate Sustainability Reporting Directive (CSRD), the need for verifiable data to substantiate environmental claims has become urgent. The CSRD and other emerging regulations demand that companies provide transparent, auditable data on their entire value chain, including Scope 3 emissions.
The Trust Protocol delivers the assurance needed to meet these new regulatory demands. The program’s field-level data provides a robust foundation for brands to track progress toward their Scope 3 reduction targets, validate Science-Based Targets (SBT) and make credible, confident sustainability claims.
The fashion industry is clearly recognizing this value. The Trust Protocol’s proprietary traceability solution saw a 413 percent year-over-year increase in Protocol Consumption Unit (PCCU) uptake. In the 2024/25 season alone, 20 brands successfully tracked approximately 126,000 tons of Trust Protocol fiber, translating to 690 million finished products. This shows that the supply chain is embracing this increased level of transparency and using tools to track cotton with greater accuracy.
Building Trust: Data Integrity and Regenerative Practices in Action
To combat skepticism and ensure the highest level of data credibility, the Trust Protocol has entered strategic partnerships with leading sustainability organizations like ISEAL, Cascale, Textile Exchange and Field to Market. A Climate-Focused Data Integrity Framework developed by this collective is designed to ensure the program’s data is robust and reliable enough for the most demanding applications, including corporate Scope 3 inventories and national-level reporting. These partnerships ensure that the Trust Protocol’s data is not only verified but also aligned with global best practices.
The on-farm impact is a direct result of growers’ commitment to continuous improvement, using a wide range of sustainable and regenerative practices. This year’s annual report highlights that 63 percent of growers are now planting cover crops, leading to a 300 percent higher Soil Conditioning Index and nearly half the erosion compared to bare-soil fields. Fifty-seven percent of acres are under no-till or conservation tillage, reducing erosion and fuel use. This dedication on the ground has seen more grower involvement each year.
To capitalize on this momentum and meet the growing demand for regenerative U.S. Cotton, the Trust Protocol launched a pilot program to trace regenerative practices and measurable outcomes among U.S. cotton growers, expanding sourcing options for brands and retailers. Using a dual framework—practice implementation and measured outcomes—the pilot tests market demand, end-to-end bale traceability and the credibility of its assurance system. Aligned with Field to Market’s guidance, it sets minimum grower requirements across soil health, water use and quality, synthetic inputs and biodiversity. A broader rollout is targeted for 2026.
By delivering five years of verifiable, field-level data, the Trust Protocol has created a system that not only helps growers demonstrate their stewardship but also provides brands and retailers with the credible, science-backed evidence needed to help navigate the future of sustainable and regulated commerce.
