Answer 2

Answer:

Automobile pollution control technology became universally adopted following the clean air act extension of 1970 as follows:

• National Ambient Air Quality Standards (NAAQS or knacks)
• National Emission Standards for Hazardous Air Pollutants (NESHAPs)
• New Source Performance Standards
• State Implementation Plans

Explanation:

Universal adoption exists not a clear aspect here. Many countries assumed features of the ACT and four regulatory programs the Act initiated:

• National Ambient Air Quality Standards (NAAQS or knacks)
• National Emission Standards for Hazardous Air Pollutants (NESHAPs)
• New Source Performance Standards
• State Implementation Plans

Another thing to note is the Act covered the whole USA but left the performance to the States due to the special challenges faced by each state. In the USA, it contains provided that vehicles start concentrating on efficiency as much as they accomplished on making big power.
