This conversation brings together representatives from different levels of the denim supply chain: brand (Boysih Jeans), mill (Candiani), and farm (the Sourcery). We talk about which part(s) of making a pair of jeans has the biggest impact on carbon emissions? Do we know? We talk about the possibilities: what role can companies operating in different parts of the denim supply chain can take towards reducing carbon emissions. And we also talk about the limits: what challenges do companies face when it comes to reducing carbon emissions? The conversation is an edited version of a webinar Kim moderated for Transformers Foundation.
