Emissions of volatile organic compounds (VOCs) are measured at GSK manufacturing operations and research and development facilities, including fugitive sources such as evaporation and leaks.
VOCs react with nitrogen oxides in the presence of sunlight, creating ozone in the lower atmosphere. This results in smog, which is a factor in human respiratory illness. We report photochemical ozone creation potential (POCP) in ethylene equivalents. Conversion to ethylene equivalents is based on the European Chemical Industry Council (CEFIC) "Responsible Care HSE Reporting Guidelines" for VOCs (1998).
