European carmakers pledged to reduce CO2 emissions by 25 percent from 1995 to 2008. We kept our word and reduced the value even more. This is not the result of short-term gimmickry. We decided years ago to develop the relevant models and engines, otherwise we wouldn't be able to offer them today.

If you, as CEO, have recognized an approach as being the right one, you have to pursue it consistently, even if some people disagree. But it is now clear to everyone that we, as an automaker, have no alternative but to take [environmental protection] course.

As far as I'm concerned, however, it is clear that the concept of premium will be increasingly defined through sustainability in the future.

We will continue to offer the most dynamic vehicles in the future. However, we have also made it our mission to be sustainable as a company.

Statistics compiled by the German Federal Motor Transport Authority highlight how successfully we have reduced fuel consumption. A few years ago, the CO2 emissions for the BMW brand were at well over 200 grams per kilometer. In 2009, that number was at 159 grams. This puts us below our direct competitors.

Prestige and premium will also play an important role in the future. But some people define these values differently today.

It isn't a given that the companies that provide mobility today will also be the ones to do so tomorrow. Every company has to work hard to make this happen.
