摘要：Climate change and energy security concerns are in our view the primary drivers in the current discussions on CO2 reduction in the automotive industry.Even though it has not been finally proven by scientists,it is widely assumed that global warming is caused by anthropogenic greenhouse gases(GHGs),with CO2 playing the most prominent role. Recent studies concluded that the economic impact of climate change in Germany would amount to costs in the region of 800 billion euros by 2050.The need for a global response seems to be the order of the day for both politicians and regulators,thus putting further pressure on the industry.With particular reference to the automotive industry,two major challenges arise:fuel saving and emission reduction.two different problems, leading to the same challenge.how to make vehicles more efficient,while keeping additional costs at an acceptable level so as to make.green.vehicles attractive to consumers.
