Using Life Cycle Assessment to Evaluate Sustainable Ingredients September 17, 2013
PRé Puts the Metrics behind Sustainability
For over 20 years we have used our inherent industry knowledge to provide our clients with relevant sustainability metrics, mapping out a clear path to success.
• In more than 21 countries • Serving more than 2500 clients • Client industries ranging from
chemicals to retail to food & agriculture
• Primary offices – Washington, DC – Amersfoort, Netherlands

What is LCA?
3
Life cycle assessment is an environmental accounting methodology used to quantify
and analyze the environmental performance of a product system.
LCA can be part of the sustainability profile for systems and products.
The Basics
• Life Cycle Inventory
• Impact Assessment
• Life Cycle Stages

Global Warming Potential
Ozone Depletion
Eutrophication
Etc.
How are LCAs used?
• Evaluate and identify hot spots
• Compare products using a standardized methodology

Evaluating Ingredients and Formulations Using Life Cycle Thinking
8
Value
• Practically and systematically evaluate the environmental implications of ingredients
• Compare ingredients and formulations using a standardized methodology
• Build scenarios to answer what if questions • Use results to make decisions internally and communicate
externally
9
Getting Started
10
Consider your place in your supply chain and determine what type of analysis to use to evaluate ingredients and formulations.
Defining the Analysis
Precursor Processes Ingredients Formulations
