conventional tool. The adoption of innovative joining techniques in body manufacturing, such as
spot welding, laser welding and bonding techniques, also cuts consumption of operating mate-
rials and energy. Technical solutions such as a modern combined heat, power and refrigeration
plant at Ingolstadt as well as heat recovery systems and the use of district heating have further-
more proved very successful for the Audi Group. The district heating contract for the Ingolstadt
plant concluded in 2009 means that the amount of waste heat from neighboring industrial
enterprises being used will continue to rise in the future.

The slight rise in overall energy consumption and CO₂ emissions is mainly attributable to the
increased production volume. The pattern of recent years demonstrates that total energy
consumption has nevertheless been kept virtually stable.
The other key environmental figures that the Audi Group observes over and above energy
consumption also reflect the increased production volume.

2) VOC emissions (volatile organic compounds): This figure comprises emissions from the paint shops, test rigs and other
facilities. From 2010 new calculation basis for the Ingolstadt plant to comply with new statutory requirements.
3) Direct CO₂ emissions: This figure is made up of CO₂ emissions generated by the use of fuel at the plant, and CO₂ emissions
produced by the operation of test rigs.
