Volatile Organic Compounds Emitted to Air

Emissions of VOCs were measured from point and fugitive sources at GSK manufacturing operations and R&D facilities. VOCs are organic compounds, generally solvents, that are used in large quantities in GSK primary manufacturing operations and in lesser quantities in secondary manufacturing and R&D facilities.

The 2001 baseline for VOC was reported as 6.6 million kilograms in 2002. A focused review of VOC reporting for 2002 by ERM revealed some inconsistencies in reporting. The values reported for 2001 were reviewed and adjusted where appropriate. The new 2001 baseline for VOC is 6.83 million kilograms. In 2002, 6.57 million kilograms was released to air, representing a 4% decrease in total VOCs released to atmosphere. The decrease is due in part to closure of one manufacturing site.

GSK set a target to decrease total VOC emissions to air by 30% by 2005 on a per unit sales basis.

Photochemical Ozone Creation Potential

VOCs are capable of producing ozone in the lower atmosphere by reaction with nitrogen oxides in the presence of sunlight. This photochemical reaction results in the formation of smog which is often worse in the hotter months. Releases of VOCs to air can be compared on the basis of their potential to create ozone relative to ethylene. Conversion to ethylene equivalents is based on the European Chemical Industry Council (CEFIC) "Responsible Care HSE Reporting Guidelines" for VOCs (1998).

For 2001, POCP was reported as 1.9 thousand metric tonnes (1.9 million kilograms). Due to changes made to the 2001 VOC baseline data, the 2001 POCP reported value has changed to 2.11 million kilograms. GSK's POCP has increased by 1.4% since 2001 from 2.11 million kilograms of ethylene equivalents to 2.14 million kilograms of ethylene equivalents.
