Footnotes

1. Energy and climate change impact for travel and transport by air, land and sea are calculated using the Greenhouse Gas Protocol starting from distance travelled, not directly from fuel use. In years before 2006 we did not collect all categories of freight transport or employee business travel. Some of the transport data are estimated and we may not capture all routes and employee air travel.

2. Climate change impact is calculated as CO2 equivalent using the Greenhouse Gas Protocol developed by the World Resources Institute and the World Business Council for Sustainable Development. Each year we review the CO2 factors and update the data for all years as appropriate. The greatest changes are generally in the updated factors for electricity.

3. In 2008 we reviewed the refrigeration equipment inventories for 2006, 2007 and 2008. Where inventories were incomplete they were estimated based on inventories in other years. We also updated the factors for ozone depletion potential and climate change emissions using WMO (World Meteorological Organisation), Scientific Assessment of Ozone Depletion: 2006, Global Ozone Research and Monitoring Project—Report No. 50, 572 pp., Geneva, Switzerland, 2007. (chapter 8). We calculate the probable releases using a factor from the British Refrigeration Association.

4. We did not have enough information to calculate climate change impact from inhaler use before 2006.

5. Water from other sources includes recycled sources

6. We focus collection of wastewater and chemical oxygen demand data primarily on the major contributors; primary manufacturing operations, pilot plants, coating activities and sterile operations. Some sanitary wastewater streams are included if they cannot be separated from production wastewater streams or if they are significant.

7. Chemical oxygen demand (COD), a measure of water pollution, is measured when wastewater leaves our sites following any onsite treatment.

8. We consider a waste to be hazardous if it has any of the properties defined by the 1989 Basel Convention or if it is radioactive, bioengineered or biohazardous. Basel Convention properties include flammability, explosivity, water or air reactivity, corrosivity, oxidising potential, acute or chronic toxicity, ecotoxicity or infection. Biological waste rendered non-hazardous after treatment is considered non-hazardous waste. We focus collection of hazardous waste on the major contributors; primary manufacturing operations, pilot plants, coating activities and sterile operations.

9. Incineration with energy recovery means burning the material and using the resulting energy.

10. Non-routine waste includes construction and demolition rubble and is not included in hazardous or non-hazardous waste calculations.

11. We focus collection of volatile organic compound emissions on the major contributors; primary manufacturing operations, pilot plants, coating activities and sterile operations.

12. We used WMO (World Meteorological Organisation), Scientific Assessment of Ozone Depletion: 2006, Global Ozone Research and Monitoring Project—Report No. 50, 572 pp., Geneva, Switzerland, 2007. (chapter 8) for ozone depletion potential and climate change emissions factors.

13. Before 2006 we did not have information about inhalers produced in Asia so it was not included in ODP or GWP calculations until 2006.

14. Before 2006 we did not have information about the amounts of refrigerants contained in equipment
