1. 1 CARBON AND ENVIRONMENTAL FOOTPRINTING 11

2. CORPORATE AND PRODUCT EMISSIONS Two viewpoints – Corporate: considers activities that create or release emissions – Product: evaluates materials and processes required to deliver or produce a product Corporate inventories best capture the aggregate emissions required to operate a company – More suitable for accounting-style activities; information based on company records – Limited granularity since emissions are aggregated Product inventories best highlight inefficiencies in bringing a good or service to market – Good granularity to determine specific emission trouble spots – Subjectivity & judgment limit accounting practicality

3. 333 CORPORATE EMISSIONS STANDARDS Only scope 1 and 2 globally defined today

4. 4 NO CLEARLY ACCEPTED GLOBAL STANDARD TODAY Carbon Trust – Established by the British Government in 2001 as an independent company to accelerate the move to a low-carbon economy – Works with organizations to reduce carbon emissions and develop commercial, low- carbon technologies – Along with Defra, co-sponsors the publication of PAS 2050, a product carbon foot printing standard WRI (World Resource Institute ) – Following the success of the Corporate Standard and Project Protocol, the WRI/WBCSD GHG Protocol is developing a new standard for product and supply chain GHG accounting and reporting – Ecolab participated in the first Product Life Cycle Analysis “Road Test” in spring 2010 ISO (International Organization for Standardization) – The world's largest developer and publisher of International Standards – Likely to enter the carbon emissions standards space 4 Note: All names and logos mentioned are registered trademarks

5. 555 CURRENT INDUSTRY POSITION ON FOOTPRINTING Carbon footprinting position paper excerpt Carbon footprint calculation methodology and supporting data are not yet sufficiently developed to allow meaningful mainstream carbon labeling of individual products Relevance of on-pack carbon labels for consumers has not been proven, and labeling should be seen as one of a number of ways to communicate with consumers on climate change The industry is looking for solutions to carbon footprint measurement and on-pack carbon labeling, which: – Are based on sound science – Are both meaningful and helpful in achieving carbon reductions – Form a meaningful part of an overall sustainability implementation strategy – Are actionable from a practical standpoint with a clear benefit/cost ratio – Give preference to a harmonized international standard Source: Excerpt from AISE (International Association for Soaps, Detergents and Maintenance Products) Position Paper
