1. LCA Applied: Unlocking the Value in Your Impact Assessment Chris Miller Seventh Generation

2. Seventh Generation’s Use of LCA Data Chris Miller Corporate Consciousness Seventh Generation

3. Seventh Generation Founded in 1988 The leading brand of household and personal care products for a living a home Grew up with the natural channel, but now growth comes from conventional channels Based in Burlington, VT 120 employees Laundry, spray cleaners, paper, baby, fem care

4. Why LCAs Matter… The process of developing LCAs is informative Our impacts span the lifecycle of our products LCAs provide a window into the hotspots and allow us to focus on the areas of biggest impact And we have a responsibility for impacts beyond those that occur beyond the boundaries of what we own We can’t manage what we don’t measure And equally important, we believe transparency around our products impacts, keep us focused on the right things

5. The Problem with LCAs Often, data specific to our supply chain is not available LCAs don’t speak don’t shed light on issues related to persistent and chronic toxicity associated with chemical use The are expensive and time consuming For a small company, we play in a large number of categories

6. What questions will LCA’s answer? What are the carbon, energy and water footprints of the product? Where are the hotspots? What are the key drivers? What can be done to reduce energy use and the carbon footprint of the product? What questions won’t LCA’s answer? Which materials and chemicals are most toxic? What is risk of exposure to workers and consumers? How do we account for sustainable palm oil / GreenPalm Certificates? Seventh Generation Detergent LCA 6

15. Tier 1 Suppliers: Diaper & Paper have the greatest impact

16. Four product categories dominate (dish, laundry, diapers & paper)Seventh Generation Detergent LCA 10

19. Non-Renewable Energy (MJ / 100 Loads) Seventh Generation Detergent LCA 13

20. Key Drivers – Non-Renewable Energy UseConventional Washer & Dryer The Use phase accounts for 91% of total energy use Drying = 50% Water Heater = 30% Washing Machine = 11% Energy use at End-of-Life is primarily for wastewater treatment, which is also related to water consumption during Use phase.

21. Non-Renewable Energy (MJ / 100 Loads)Life Cycle Excluding Use Phase - Detail Seventh Generation Detergent LCA 15

22. Key Drivers – Non-Renewable Energy UseExcluding Use Phase Wastewater treatment accounts for more energy use than material production WWT = 34% Material Production = 31% Ingredient Transport = 14% Distribution = 11% Packaging = 9% Manufacturing = 0.2% Notes: Pumping of treated water represents 80-85% of electricity use for WWT. WWT accounts for 4% of US electricity use. Source: Water and Sustainability: U.S. Electricity Consumption for Water Supply & Treatment— The Next Half Century, EPRI, Palo Alto, CA: 2000. 1006787.

24. Sodium Citrate = 27%

25. SLS = 16%Note: Better LCI data is needed for sodium citrate. LCI data was not available so sodium tripolyphosphate was used as a surrogate. Seventh Generation Detergent LCA 17

26. Water Depletion (M3 / 100 Loads) Seventh Generation Detergent LCA 18

27. The Hotspots What are the carbon, energy and water footprints of the product? Liquid Laundry Carbon Footprint = 142 kg CO2 equiv. (102 for Energy Star) Energy Footprint = 2,282 MJ (1,652 for Energy Star) Water Footprint = 14,000 L (6,800 L for Energy Star) Where are the hotspots? Use and WWT, Material Production What are the key drivers? Consumer behavior, appliance efficiency, sourcing What can be done to reduce energy use and the carbon footprint of the product? Laundry: Energy Star appliances, cold water wash, line dry, material sourcing Seventh Generation Detergent LCA 19
