CottonConscience is exploring how satellite observations, DNA tagging and water-system information can help fashion businesses understand where their cotton comes from and how it is grown.

The project tackles traceability by connecting conditions in cotton fields with material moving through the supply chain. Its approach combines environmental observations with physical tagging and supply-chain records to give buyers stronger evidence for sourcing decisions and sustainability claims.

According to the CottonConscience project team, the work uses Sentinel-1 and Sentinel-2 data from the Copernicus Data Space Ecosystem, alongside openEO tools. Open data, software and standards underpin the approach with scope to incorporate commercial imagery and other datasets where needed.

Water is central to the project. Satellite observations can help assess growing conditions and water demand whilst local information supplies context that imagery alone cannot provide. The team brings together expertise in Earth observation, water systems, DNA tagging and fashion buying.

A project update published by ESA on 22 September reports that the feasibility study completed this month. Farm Trace and Water Trace capabilities were incorporated into a clickable ASK MIRANDA demonstrator, connecting environmental and traceability information with buying, sourcing and sustainability workflows. ESA says the work is suitable to progress to a demonstration or pilot phase for validation in live supply chains.

For commercial EO businesses the opportunity lies in making observations useful within a customer’s everyday decisions. CottonConscience illustrates how satellite analysis can contribute to a broader evidence service, supported by field information and specialist knowledge.

The next test is to find whether the approach can deliver reliable, affordable evidence across complex supply chains. Satellite imagery can reveal conditions at a farm but connecting those observations to cotton in a finished product requires the other traceability components to work as well.
