Environmentalists and automakers sometimes are at odds about cleaning up the environment.
The differences can involve vehicle-related issues such as emissions, fuel economyand the ability to recycle as well as the manufacturing process.
No one denies it's a good idea to protect the environment, though sometimes the cost-benefit ratio gets in the way.
But now BMW has cut operating costs as a direct result of investments made to improve environmental quality.
For several years, BMW has been aggressive in reducing the energy it uses and the pollution it produces.
Last year, the German automaker spent about $40 million on programs to reduce the water it uses in the manufacturing process and to adopt new paint technology, according to Automobilwoche, the German-language sister publication of Automotive News.
So far this year, BMW already has saved more in cleaning and waste disposal costs than it has spent.
That proves it is possible to do well by doing good.
