Why a Product-Lifecycle Approach?

• In 2006, we had several programs in place to address environmental impacts

associated with the production of our products and the operation of our facilities

– Environmental compliance programs

– Supplier Code of Conduct program

– Global Effluent Guideline program

– Levi’s® eco products (e.g., using organic cotton)

• We needed a credible, science-based method for measuring the full

environmental impact of our products so that we would be able to identify a vision and set of priorities for our environmental work going forward

• We commissioned a lifecycle assessment (LCA) of two of our core products,

which yielded some surprising results

• By taking a product-lifecycle approach to our work, we were able to develop

a set of strategies to address the greatest impacts of our business on the environment

• Our product-lifecycle approach addresses both environmental sustainability

(3)

What Is a Product-Lifecycle Assessment?

Quantitative method to evaluate the environmental impact of

products using:

– Lifecycle perspective (system analysis) – e.g., from the cultivation

of cotton to the end of the product’s useful life (“cradle to grave”)

– Mass and energy balance (input/output inventory)

• Direct Data – inputs and outputs associated directly

with product

• Indirect Data – inputs and outputs used to make the direct inputs (often

using extensive industry-average data sets)

– Impact assessment categories

• To translate the input and output data to the

environmental impacts of the system

Typically, does not include:

– Social impacts

“…the compilation and evaluation of the inputs, outputs and the potential

environmental impacts of a product system throughout its lifecycle”

A Credible Methodology

Forty-year history

1969: Glass bottle recycling vs. one-use PET bottles

1970s: Energy crisis prompted energy-efficiency studies

1997–2001, 2006: International Standards Organization (ISO)

14040 series

Consensus on LCA practice

University graduate programs

LCA professional certification (LCACP)

LCA to be integrated into LEED program for certification of green

buildings

United Nations Environmental Program (UNEP) Lifecycle Initiative

European Union Integrated Product Policy (IPP)

National Institute of Standards and Technology (NIST) – using LCA

Our Project Scope

Selected high-volume product:

– Levi’s® 501® jean, medium stonewash

– Produced for the U.S. market during the 2006 production year

Studied the full lifecycle - cradle to grave

Data compiled from

– LS&CO. suppliers

– GaBi 4 software datasets (used by LCA professionals, academics,

government and other objective parties)

Followed ISO 14040 series standards for results intended for

internal use only

Additional review (Phase 2) enables LS&CO. to share select data

publicly and refer to LCA findings in conversations around our

sustainability story and programs

What We Learned from Our Product Lifecycle Assessment

When we look at the full product lifecycle, the majority of environmental

impacts occur in lifecycle phases outside of our direct control

In order for us to decrease our overall environmental impact, we need

to continue our efforts within our own sphere of influence in addition to

focusing on:

– Cotton production: the cultivation of our most important raw material

– Consumer engagement: we are a consumer-facing company, in constant

conversation with the consumer about style and quality. We will engage and educate our consumers on the environmental impact of their fashion choices and the responsible care of their washable garments

(20)

Examples of Our Product Lifecycle Approach in Action

Engaging consumers:

– Levi Strauss & Co. partnered with the Alliance to

Save Energy and Proctor & Gamble, makers of

Tide® Coldwater, to co-promote our Signature by

Levi Strauss & Co.™ jeans in Wal-mart stores,

encouraging consumers to save energy and money by washing their jeans in cold water

– Product care labels: The Levi’s® brand is in the process

of changing all care labels on the brand’s products,

instructing consumers to wash in cold water and tumble dry medium. The new instructions will allow consumers to reduce their own environmental/climate change impact and save money on their utility bills

Reducing product packaging

Incorporating resource-efficiency factors in product design and

manufacturing, including finishing technologies that allow us to reduce

our water and energy consumption

Addressing cotton sustainability through participation in projects

(21)

Benefits of Our Product Lifecycle Assessment

Helps us focus on the most significant environmental

impacts as we develop and evaluate sustainability programs

and policies

Aids discussions with product designers, product managers,

merchandisers and other employees on the concept of

designing for sustainability

Supports engagement with external stakeholders as we
