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 – 2

What is LCA? 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. 3

The Basics • Life Cycle Inventory • Life Cycle Stages CO 2 21 g Raw Material N 2 0 10 g Extraction VOC 20 g P 2 g Disposal Processing Nitrate 20 g CH 4 8 g • Impact Assessment Use Distribution Global Warming Potential Retailing Ozone Depletion LCI Eutrophication Etc. 4

How are LCAs used? • Evaluate and identify hot • Compare products using a spots standardized methodology Disposal 100% 100% 90% 80% Use 80% 70% 60% 60% Retail 50% Product A 40% 40% Product B Distribution 30% 20% 20% 10% Processing 0% 0% Global Energy Ozone Global Warming Raw Material Warming Demand Depletion Potential Extraction 5

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 Consider your place in your supply chain and determine what type of analysis to use to evaluate ingredients and formulations. 10

Defining the Analysis • Palm Oil Esterification Emollients Soap • • • Corn Starch Coloring Agents Shampoo Hydrolysis • • • • Decyl Alcohol Hydrogenation Fragrances Lipstick • • • • Processes Ingredients Formulations Precursor Life Cycle Inventory Impact Assessment Results 11

Life Cycle Inventory Create LCI Impact Assessment Results Ingredients • Identify precursors • Identify processes Precursors Processes • Determine data availability ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 12

Advanced Screening Tool • In addition to screening, use of full life cycle models of product systems • More advanced analysis • SimaPro LCA software 18

Life Cycle Example Output- Advanced Inventory Screening Tool Impact Assessment Results 19

Utilizing Results Results Baseline Evaluate Identify Compare Compare Impacts for Individual Reduction Ingredients Formulations Product Groups Ingredients Opportunities 20

Life Cycle Inventory Utilizing Results Impact Assessment • Rank ingredients and formulations based on Results environmental impact • Additional ingredients can be added over time Product A High Impact Ingredient 2 Ingredient 3 Ingredient 1 Global Low Impact Energy Water Waste Warming 21

Conclusions: Improved Decision-Making Through LCA • Internal uses – Scenario building – Process evaluation – Performance quantification • External uses – B2B or B2C communication – Respond to customer inquiries – Identify new business opportunities 22
