This case study analyses the total water footprint for the brand Guess Inc., a US clothing company.
It attempts to analyse this using a spacially explicit life cycle assesment model meaning, mapping of water consumption in the processes with the location of the production process. This could assist brand owners having suppliers in multiple locations to adapt to sustainable water management action plan.
The study used a hybrid approach comprising life cycle assessment (LCA) and water footprint assessment (WFA) to analyse the total water consumption across the jeans manufacturing process. While LCA was used to assess the blue water or surface and ground water, WFA was used to assess the green water or rainfall which acts as an indicator to assess if the product system is growing crops in arid areas. Results showed that sustainable measures need to be taken in the cotton cultivation sub-sector.
