Materials account for over 60% of the environmental impact of a Nike shoe. The apparel industry produces enough textile to cover the state of California every year- that's 400 billion square meters. These are just two of the statistics Nike Inc has included in its sustainability reports over the years, and released recently to support the launch of their Making App.
For eight years, the designers at Nike have been using information from their Materials Sustainability Index which measures impact of common materials from four perspectives:
- Energy/Greenhouse Gas Intensity
- Water/Land Intensity
- Physical Waste
The intent is to but this knowledge in designers hands to help increase awareness and implication of choices they make on a daily basis. Understanding that sustainability, particularly in fashion, is not the only factor in choosing materials - but Nike is hoping the app is a first step in a much bigger materials conversation.
