“five years ago I would not have come as a speaker at such an event!” Volker Quaschning, Professor at the University of applied Sciences HTW in Berlin (D), and co-founder of the science Initiative, “Scientists for the Future,” selects to the beginning of his lecture in the Volkswagen automobile Forum unter den Linden, clear words.

in addition to high-level representatives from the VW group, which give on this day, the journalists insight into the change of VWs to electric brand, is Quaschning, a neutral expert. He also points out: “If I could not present what I would like to, I wouldn’t have come.” To add to in the next sentence: “in the past, VW was not necessarily for his commitment to sustainability is known.”

Without a change in response

Quaschning here is to emphasize that the world was on the verge of climate disaster. Without a rethink, the mobility, is dedicated to the human civilization within decades of the demise. “In just the last few years, the global average temperature has risen by one degree Celsius. If we continue like this without changing what is added to 2100 for at least 3 to 4 degrees of warming!”

What that would mean, shows Quaschning in a graph: the increase in large were no longer parts of South America, Africa, and Asia habitable – almost any day would be a deadly Hitzetag. In order to prevent the worst, had to be limited rise in temperature, as in the Paris agreement of 2015 agreed, to well below two degrees. The Problem: Even with a marked decline in CO2 emissions needed to work in the world as of 2040 climate-neutral.

make It fast

go to The topic of mobility plays a huge role in this: “10’000 km the car gives an average of 1.5 tonnes of CO2,” explains Quaschning, “this is three times as much as a resident of Bangladesh in the year!” Without a shift to electric cars, the climate target is unattainable and it had to go fast.

“by 2025, we have to say goodbye to the petrol and Diesel,” says Volker Quaschning. Although buy an E-car resources – in the production at the moment, even more than a nitro. “However, the climate balance is improving more and more, and in the operation of E-cars in Germany, only half as much CO2 as Diesel-powered.”

Half the number of cars

lower The target should be according to Quaschning, renewable energies, the CO2 emissions of E-cars to zero. Even then, says Quaschning, must change our mobility behaviour: “In the whole of Europe the number of cars must be reduced in the next 20 years on the half – otherwise, disaster is imminent.” Whether this is realistic is another matter.
