In 1982, California became the 20th state in the nation to adopt a vehicle inspection and maintenance (Smog Check) program. BAR became the administrator of the California Smog Check Program in 1984. Consumer Programs
The primary emissions studied include hydrocarbons, volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and sulfur oxides. Starting in the 1950s and 1960s, various regulatory agencies were formed with a primary focus on studying the vehicle emissions and their effects on human health and the ...
In 2019, it contributes to about 31% of global emissions and 24% of emissions in the EU. In addition, up to the COVID-19 pandemic, emissions have only increased in the transport economic sector. [ 64 ] [ 65 ] In 2019, about 95% of the fuel came from fossil sources.
