� Another very successful measure involved a reduction of suction flow volumes in processing machines with
the help of computer-based simulation calculations. The optimizations achieved here lowered such flow
volumes by 20–30 percent, saving 30,000 megawatt-hours of energy.
� Ventilation at one production hall was adjusted to conform to actual needs by using a more efficient
ventilation system and new electronically controlled motors. This resulted in annual savings of 1,200
megawatt-hours of electricity and 3,800 megawatthours of heat.
� A key administrative measure was a synchronization of ventilation and lighting with actual production times,
using an operating-time system. This led to annual savings of 21,000 megawatt-hours of electricity and
27,000 megawatt-hours of heat.
� Increased employee awareness of the need to conserve energy also yielded savings, with Intranet campaigns
and posters and flyers sensitizing employees and encouraging them to get involved.
� A newly introduced sticker identifies “disengageable machines,” making staff more aware of equipment that
can be completely shut down when not being used for production.
Specific CO 2 emissions from production
Altogether, in 2007 the energy efficiency project in Untertürkheim reduced electricity consumption by 51,700
megawatt-hours and heat consumption by 130,200 megawatt-hours compared to the reference year of 2005.
The project also cut water consumption by 500,000 cubic meters. In recognition of these accomplishments, the
project team was presented with Daimler’s Environmental Leadership Award (ELA) in November 2007.
CO 2 emissions. Total energy-related CO 2 emissions at all plants decreased by 2.7 percent to 3.78 million tons in
2007 (see chart above). The lower decline in emissions compared to energy consumption was due to the fact
that particularly high savings were achieved in the areas of fuels and district heating requirements, while
consumption of electrical energy, which accounts for a high proportion of indirect CO 2 emissions, rose slightly.
The graph above left, which shows CO 2 emissions from production plants in relation to the number of vehicles
produced, makes it clear that energy-saving projects at the Mercedes-Benz Cars were already beginning to have
an impact in the second year of implementation. Thanks to new and efficient production equipment and a sharp
increase in production, the Group’s “Vans, Buses, Other” segment once again recorded lower specific CO 2
emissions than in the prior year. At the same time, the specific CO 2 figures for Daimler Trucks rose due to the
decline in production at that division.
Emissions of other greenhouse gases, such as coolants, are negligible. The greenhouse effect resulting from such
gases is less than one one-thousandth of the total figure for greenhouse gas emissions generated by Daimler.
