Summary
Functional unit: 
Levi's 501 Jeans and other core LS&Co. products
Goal and scope of the summary: 
To focus on the environmental impacts as we develop and evaluate sustainability programs and practices. Inform product decisions to reduce environmental impact from design, materials, and manufacturing. Support engagement with external stakeholders to reduce the impact of materials and consumer care.
  • Consumer care and cotton cultivation remain the most significant impact areas. 

General Findings: 

  • Water consumption: Fiber production, predominantly cotton, contributes by a wide margin to water consumption.   
  • Climate change: Consumer care and fabric production are the most significant phases for climate change impact and energy.   
  • Expanded Scope: By expanding our scope to include the leading cotton-producing countries, we've seen the water consumption from cotton cultivation increase to 68% of the total impact.   

Consumer Use Findings: 

  • Washing every 10 times a product is worn instead of every 2 reduces energy use, climate change impact and water intake by up to 80%.

Significant differences between regions:

  • Consumers in China are leading the pack: when it comes to laundering their jeans, they mostly wash in cold water and air dry. 
  • American consumers had the highest water intake and use of non-renewable energy. The goof news is that Americans more prevalently use cold water.  
  • Consumers in the UK and France mostly air dry their jeans but they use more hot water than Americans or Chinese consumers.  
  • Consumers in the USA, UK and France wash their jeans more frequently than in China.  

Other stages still have an impact, but to lesser degrees:

  • Fabric assembly, which includes yarn spinning, dyeing, weaving, and fabric finishing had notable contributions related to climate change impact and non-renewable energy consumption.  
  • Life cycle stages that had minimal contribution to impact include: fabric transport, product transport, packaging, production wastes, distribution, retail, and end of life waste.

Every region has a different

Every region has a different way of treating there fabrics as you have mentioned how people from China, US and UK uses both cold and hot water when washing their jeans but Chinese people washes there jeans less often then of the US and UK citizens. We all can take part in making our environment better and spread awareness regarding it. I use my help with assignment website's blog to spread it and share various different blogs and articles to do my part of it. Levis strauss is one of the most environmental friendly productions out there among the rest of the others.
