Early in the 1950s scientists discovered that vehicle emissions were a significant factor that had been causing the air quality to deteriorate. [7] This led to the introduction of vehicle emissions standards in California in 1966, furthermore due to the seriousness of the problem, in 1970 the Clean Air Act was introduced in order to regulate these standards all over the United States.
