California's toxic air pollution

California’s toxic air pollution has reduced by 78% in 24 years, all thanks to the air pollution control standards adopted in the state. The control standards have reduced the amount of diesel particulate in the air. These standards have also reduced cardiopulmonary deaths caused by poor air quality.

UC Berkeley’s Scientists are commending the diesel engine standards and other measures for helping to reduce air pollution. If you have ever seen Los Angeles before the adoption of the Clean Air Act, you would know how these measures have helped a lot.

Our analysis of mobile-source DPM (diesel particulate matter) emissions suggests that many California sector-based policies have been highly effective relative to the rest of the US.

They realized that within the year 1990 and 2014, the level of DPM in the skies of California reduced by a whopping 78% while cancer and cardiopulmonary deaths caused by diesel pollution reduced by 82%.

The greatest decline in California’s toxic air pollution came from tractor-trailers. This is quite unsurprising due to the fact that these trailers are powered by diesel and they cover many miles. There was also a reduction in passenger and construction vehicles and this had a great impact on air pollution in California.

The overall use of diesel in California increased over this period, this indicates that strategies to move to refined fuels and fitting existing vehicles with pollution filters are effective
