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.

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.

Naturally, we will continue to offer very powerful vehicles in the future. Nevertheless, no other manufacturer has reduced the CO2 emissions of its fleet as substantially as the BMW Group.

I have told our senior executives that I will slaughter holy cows if it benefits the company's long-term success. When we asked ourselves whether Formula 1 still matched the concept of a sustainable company, the clear answer was no.

The manufacturers of mechanical typewriters believed that they had developed sufficiently when they introduced electric typewriters. Then came the PC, and the deeply traditional makers of typewriters disappeared from the market.

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.

In the European Union, a fleet average of 95 grams of CO2 per kilometer will be permitted in 2020. This corresponds to fuel consumption of about four liters (per 100 kilometers; about 59 mpg). We have to continue reducing the fuel consumption of our vehicles and offer hybrid and electric vehicles, or else we will be unable to achieve these values.
