5. To engage product design teams and the global supply
chain of the apparel and footwear products in
environmental sustainability.
To help product teams select materials with lower
environmental impacts, as reflected by better scores on
MSI.

6. • The MSI was originally developed by NIKE with
consultants Brown and Willman and is a result
of more than eight years of materials research
and analysis
• In July 2012, it was adapted by the Sustainable
Apparel Coalition (SAC) and incorporated into
the Higg Index

7. MSI has two parts
One part of the MSI is web-based –measures the Base
Material Scores – on a 50-point scale
The Base Material Score examines publicly disclosed LCA
studies, industry reports and supplier-derived
information to assess the four impact areas and calculate
a score for each raw material using a representative
supply chain.

10. The MSI uses a mathematical
function to transform
Chemistry, Energy and GHG
Intensity, Water and Land
Use Intensity, and Physical
Waste data into a percentile
score for each indicator
Base Material Scores

11. Life Cycle Scope
Each Base Material Score is derived using life cycle
inventory (LCI) information that tracks material
impacts for each indicator from cradle to gate
Cradle to gate life cycle is divided into two phases-
Phase-1: Farm, forest or wellhead to an intermediate stage
Phase 2: The intermediate stage to the finished textile or
component part
(2a)
15. Calculation and Data Assumption
Chemistry combines human
health hazard evaluations for
Carcinogenicity
Acute Toxicity
Chronic Toxicity
Combined Reproductive Toxicity
Endocrine Disruption
(considering exposure)
Evaluation in two phases:
Phase-1 spans the origin of raw
materials to a cone of yarn.
Phase-2 spans greige fabric through
finished textile.

16. The exposure assumption is based on the
geographic location of the activities in the
phase and whether the activities are an open
or closed system

17. Chemical substances that are identified as the worst-
case human health hazard in each of the two phases
are paired with appropriate exposure assumptions
using the matrix in the following tables to determine
a score for each phase.

18. Energy consumption
Sum of the Finishing Energy Total and the Energy Process Total
multiplied by 1.02 if the material is a fabric.
Here is the trend-line and polynomial function used for Energy-
(3a)
19. GHG calculation
GHG Total is calculated as the sum of the
Process Total and the Finishing Total.
The trendlines and polynomial function for GHGs-
(3b)
20. Water Total is calculated as the sum of the Water Process Total multiplied by
1.02 if the material is a fabric and the Water Finishing Total

21. Land use scoring
That value is the total number of hectares needed to produce
one kg of harvested raw material for a bio-based material.
the trendline and polynomial function for Land Use.
(3d)
22. Physical waste
Physical Waste is divided into the
following categories:
Hazardous
Municipal Solid Waste
Industrial
Recyclable/Compostable and
Mineral.
Physical Waste is the waste generated
from cradle-to-gate, based on
aggregating the European Union waste
categories used in Eco-Profiles
(3e)
23. Physical waste scoring
Hazardous Wastes,
Municipal Solid Wastes,
Industrial Wastes,
Recyclable/Compostable Wastes, and
Mineral Wastes .
Nike uses all these trend-lines and
polynomial functions for Physical Waste.
(3e)
24. Environmental trade-offs
Materials may vary in their impact areas.
Example- material ‘X’ has a low water energy consumption then
material ‘Y’ but has high water intensity then ‘Y’
MSI web-tool considers this cross environmental
trade-offs and present the data through graphical
representation

33. Not a substitute for full life cycle assessment (LCA), nor
provides footprint endpoint data
Limitation
MSI does not conform to standard LCA methods
the MSI looks only at the impacts of materials from cradle to gate
does not include consumer use or end-of-life reuse phases.

36. 'Organization for Economic Cooperation and Development -
OECD' A group of 30 member countries that discuss and
develop economic and social policy. OECD countries are
democratic countries that support free market economies.
The cradle-to-gate life cycle spans the origin of raw materials
to a finished textile or component part, ready to be shipped to
a product manufacturing facility.
An eco-profile is a useful tool for fully determining Ingeo's
environmental impact. The profile adds up all of the inputs &
outputs from our manufacturing process (like water to grow
feedstocks, CO2 sequestered by plants, energy to produce
fertilizers, and greenhouse gases emitted by our facilities) from
the field to the polymer factory exit gate...or from the plants
being grown to boxes of Ingeo leaving our plant in Blair, NE.
This calculation helps us determine Ingeo's impact on several
indicators including greenhouse gas emissions and non-
renewable energy use.
