The scores for hemp and flax are driven by water and eutrophication impacts. The eutrophication impact is coming from direct emissions to water (nitrate, phosphorus, etc.) during hemp cultivation. It’s also important to consider that this data is based on data in the Quantis WALDB database, but it is also one dataset that represents a “generic” fiber based on the best data available to us. Farms that have much more sustainable or unsustainable practices would need to submit data to us to be reflected. We are expecting to have more flax and hemp processes included in future updates of the Higg MSI.
