2. We are in the “urban millennium”
Population Growth
In 2007 ~ 50% of the world's population
was living in cities, an increase from 3.5
B to 4.7 B until 2030
Cities as Powerhouses
50% of world GDP is produced in
cities with a population over 750,000
Major energy and climate factor
75% of energy consumed in cities;
80% of CO2 emissions are produced
in cities

11. Electromobility: clean, quite and
efficient – mobility of the future!
Challenges like scarcity of raw
materials, global warming, and
urbanization cannot be met by fighting
the symptoms. They require
sustainable, comprehensive solutions
that will enable us to achieve our
development goals while also
preserving our natural resources.
From a climatic perspective, the quiet
and emission-free electric vehicles are
ideal for urban environments.
Furthermore they are the only means
of travel that can provide both clean
and highly individualized mobility.
