Good Earth Cotton Highlights Evidence-Based Fibre Claims

Good Earth Cotton® (GEC) is highlighting the growing importance of evidence-based environmental claims as new European Union rules raise the standard for substantiating sustainability statements.

From 27 September 2026, measures implementing the EU’s Empowering Consumers for the Green Transition Directive, known as EmpCo, will apply across EU Member States. The measures raise the evidentiary threshold for environmental claims and restrict certain generic claims that lack recognised environmental performance evidence.

For GEC, the regulatory development reflects an approach it has built over eight years. The model combines primary farm-level data, independently verified outcomes and physical fibre verification at source.

EU Rules Raise the Evidence Bar

European Commission analysis found that 53% of environmental claims examined in the EU market contained vague, misleading or unfounded information. The analysis also found that 40% lacked supporting evidence, while half of the green labels examined had weak or no verification.

The findings underline a broader shift in sustainability communication. Environmental claims increasingly need specific and credible evidence.

This shift also matters for fibre production. Cotton accounted for around 19% of global fibre production in 2024, equivalent to approximately 24.5 million tonnes. Recycled cotton represented around 1% of global cotton production, at approximately 300,000 tonnes.

Therefore, environmental evidence linked to cotton already in production remains important alongside the development of recycled and next-generation fibres.

GEC Focuses on Measured Outcomes

Good Earth Cotton® defines its approach to Next Generation Farming through an outcomes-first model. The system measures environmental performance against established baselines using primary farm-level data.

Independent verification then assesses the reported outcomes. The process also connects the data to fibre that undergoes physical verification at its source.

The model currently represents approximately 60,000 metric tonnes of physically verified GEC fibre. According to the company, this volume is enough to produce around 300 million T-shirts for the global market.

The model distinguishes between farming practices and measurable outcomes. Practices describe the actions taken on a farm. Outcomes show the resulting change.

This distinction matters because farms operate within different soil, climate, water and production conditions. As a result, the same intervention may not deliver identical results across different locations.

“For years, we used the language of regenerative agriculture because it helped describe the direction farming needed to take. But a practice is an intervention; an outcome is the evidence,” said Danielle Statham, Founder and Owner of Good Earth Cotton® and FibreTrace®.

“The next generation of fibre will not be defined by the practice it claims. It will be defined by what can be measured, independently verified and connected to the physical fibre itself.”

Three-Part Evidence Architecture

GEC’s evidence model connects three core elements: measured outcomes, verified data and verified fibre.

Farm-specific primary data forms the foundation. GEC assesses this data against established baselines and monitors it over time.

For greenhouse gas emissions and removals, GEC uses the internationally recognised ISO 14064 framework. The framework supports the quantification, monitoring and reporting of greenhouse gas information.

Downforce Technologies measures and quantifies farm-level data. Meanwhile, SGS independently verifies the greenhouse gas assessment under ISO 14064-3.

This process provides independent assurance over the reported greenhouse gas outcomes.

FibreTrace® adds another layer of physical verification. It establishes a physical GEC identity at source. Defined verification events throughout manufacturing can then confirm the detected presence of marked GEC fibre.

“Primary data provides the evidence. Independent verification provides the confidence. Physical fibre verification preserves the connection.” Statham added.

Moving From Claims to Substantiation

GEC says it does not present EmpCo as an endorsement of its model. Instead, the company views the directive as part of a wider shift in sustainability communication.

The focus is moving from broad environmental claims towards information that companies can measure, substantiate and independently verify.

For the fibre sector, this shift places greater emphasis on traceability and evidence. It also highlights the importance of connecting environmental data with the physical material moving through the supply chain.

As environmental regulations develop, brands and fibre producers may face greater pressure to demonstrate the basis of their sustainability claims. Evidence-based systems can therefore play an increasingly important role in communicating environmental performance.
