Automakers have invested hugely in reaching air quality improvements and in developing diverse automobiles that run on alternative fuels including those from sustainable sources or that use hybrid technology using both gasoline or diesel engines and electric power. Because consumers, as well as different regions of the world, favour different technologies, automakers are developing a range of automobiles that run on different fuels.

The automobile industry is also a major innovator, investing almost €85 billion in research, development and production. The auto industry plays a key role in the technology level of other industries and of society and is one of the largest investors in research and development, with several manufacturers leading the Top 10. Vehicle manufacturing and use are also major contributors to government revenues around the world, contributing over €430 billion in twenty-six countries alone.
