The document summarizes the Volkswagen emissions scandal that unfolded from 2006 to 2015. It began when VW planned to increase its low U.S. market share and decided to install cheat devices to pass emissions tests. In 2013, investigations began after tests found VW diesel vehicles emitted nitrogen oxide at levels over EPA limits. In September 2015, the EPA exposed the scandal, and VW admitted installing software in 11 million vehicles worldwide to cheat emissions tests. The CEO resigned as the company faced lawsuits of $25 billion and a 34% drop in share price wiping out $16 billion in market value.
