A
/ EMISSIONS REDUCTION AND
RESOURCE EFFICIENCY
Reducing energy consumption and the related emissions is a
special priority within our Company’s environmental activities.
We pursue an integrated approach and consider not just CO2
emissions generated by a vehicle’s operation, but also raw
materials extraction, the production of component parts and
their assembly, the energy flow in the production facilities,
and recycling. In this connection, we intend to reduce our
specific location-based and company-related CO2 emissions by
25 percent by 2018 compared with the specific figure for 2010.
By 2020 we also aim to cut carbon dioxide emissions from the
energy supply at the Ingolstadt and Neckarsulm locations by
40 percent compared with the specific figure for 2010. Our
long-term vision is of an entirely carbon-neutral automotive
manufacturing process. Starting with the Ingolstadt site, we
aim to roll out this concept gradually across other sites. In
addition to continuously optimizing our processes, we focus
above all on energy-saving measures when planning plant and
buildings and defining logistics processes. Eco-electricity has
been in use at the Ingolstadt site since 2012. This measure
helps to avoid up to 290,000 metric tons of CO₂ a year. The
Brussels location has also been using renewable hydroelectric
power since 2012. Over the period of 2010 through 2018, the
Group is likewise striving for a 25 percent improvement in the
key environmental metrics for energy, fresh water, waste dis-
posal and organic solvents (volatile organic compounds).
In addition to logistics, the production and supply facilities in
particular are significant in terms of permanent efficiency
improvements. For example, the use of ultra-lightweight tools
made mainly from carbon-fiber-reinforced polymer (CFRP) in
body manufacturing helps to save as much as 40 percent in
electricity compared with conventional equipment. Innovative
joining techniques in body manufacturing – such as spot weld-
ing, laser welding and bonding techniques – likewise help to
cut consumption of operating materials and energy.
The modern paint shop at our Győr production location is also
helping us cut back on the amount of energy used. Compared
with the conventional wet separation technology, energy con-
sumption there can be reduced by up to 50 percent with the
help of a dry separation system with air recirculation. Solvent
emissions can even be cut by more than 70 percent. Combined
heat and power, heat and energy recovery systems and the use
of district heating have proven very successful for the Audi Group.
This is exemplified by the new Münchsmünster site, where
particular attention is paid in all areas to the efficient use of
energy. Alongside an ultra-efficient combined heat and power
plant, the waste heat from generating compressed air is fed
back into the heating system, for instance; in addition, process
heat is used for surface heating, and hall ventilation systems
are equipped with heat recovery. The Lamborghini brand, too,
has long been systematically identifying ways of reducing
energy consumption. In July 2012, it completed the new Design
Center for the development of prototypes and pre-production
models. It is equipped with state-of-the-art technology and was
the first building of its kind in Italy to be awarded an “A” energy
rating. This approach was also systematically refined for the
new Logistics Center. Opened in September 2013, this building
has also earned an “A” energy rating.
