measures” directive). By relaxing the legal length
restrictions, it may be possible to design vehicles in
an aerodynamic way without losing any loading
space. As air resistance is lower in a rounded and
streamlined design, this leads to lower fuel con-
sumption. Considering the vehicle as a whole could
save up to 25 percent in fuel through the aerody-
namic design of cabs and trailers, as well as addi-
tional technical innovations.
In the Power Engineering segment, the Inter-
national Maritime Organization (IMO) has laid
down the International Convention for the Preven-
tion of Pollution from Ships (MARPOL), which
phases in limits on exhaust emissions from marine
engines. Emission limits also apply, for example,
under EU directive 97/68/EC and the US EPA
(Environmental Protection Agency) marine regula-
tions. As regards stationary equipment, national
rules are in place worldwide and have to be ap-
plied locally. On 18 December 2008, the World
Bank Group set limits for gas and diesel engines
in its “Environmental, Health, and Safety Guide-
lines for Thermal Power Plants”, which are binding
if individual countries have adopted no or less
strict national requirements. In addition, back in
1979, the United Nations adopted the Convention
on Long-range Transboundary Air Pollution, set-
ting limits on total emissions as well as nitrogen
oxide limits for the signatory states (including all
EU states, other countries in Eastern Europe, the
USA and Canada). Enhancements to the product
portfolio in the Power Engineering segment are
focusing on improving the efficiency of the
equipment and systems.
In order to be optimally prepared for the third
emissions trading period starting in 2013, the
Volkswagen group calculated and reported the CO2
emissions to be reported for its German plants in
accordance with the German Data Collection Regu-
lation (DEV 2020). The appropriate applications for
the allocation of certificates to the German Emis-
sions Trading Authority (DEHSt) have been submit-
ted for all plants. The other plants in the European
Union were also checked in accordance with the
national laws in force at those locations and action
was taken to ensure that applications were sub-
mitted to the relevant national authorities in good
time.
The changes to the Emissions Trading Directive
and their transposition into German law have been
completed. From a current perspective, the number
of plants included in the European emissions trad-
ing system from 2013 onwards and the related
amount of CO2 emissions requiring to be traded will
not increase significantly.
The allocation of the necessary emissions certif-
icates will change fundamentally as of 2013. They
will no longer be allocated mostly free of charge
through national allocation plans. Instead, a steadily
falling number of certificates, for heat generation
using natural gas for example, will be allocated free
of charge. Companies will have to purchase any
additional certificates they require at auction. Unlike
before, CO2 emissions certificates for power gen-
eration will have to be purchased in full. Estimates
