The production-related data were determined at 226 Henkel sites in 57 countries, including the National Starch sites acquired in 2008. These sites represent more than 95 percent of our worldwide production in 2008. The data are validated centrally for year-end reporting and also verified locally within the framework of our international audit program. Any differences in data discovered or reported at a later date are corrected retroactively in our reporting system.

Henkel measures the direct and indirect carbon dioxide emissions of its major production sites which account for more than 95 percent of the global production volume. Almost all carbon dioxide is released as a result of energy generation. Our reporting includes our own carbon dioxide emissions released as a result of Henkel activities, as well as  carbon dioxide emissions formed during the generation of bought-in energy  at non-Henkel sites. Process related emissions are not relevant. Transmission losses and carbon dioxide emissions generated upstream (e.g. exploration, transport) are not included. The emission factors are country specific and derived from established lifecycle assessment databases.

Henkel is growing, as is the number of sites contributing data to the environmental indicators – from 141 in 2004 to 226 in 2008. As growth does not occur at a uniform rate, there are jumps in the figures. The indicators of the National Starch sites have been integrated into the reporting system since these businesses were acquired in April 2008. The National Starch figures for 2008 are shown separately in the following charts, in order to highlight the influence of this acquisition on our environmental indicators.
