Differences between setting fuel economy and emissions standards Under the Clean Air Act, EPA is obligated to reduce pollution from mobile sources like passenger cars and trucks when those emissions are a risk to public health and/or welfare. Additionally, there are incentives for natural gas vehicles and electric vehicles.

EPA last year, the new draft rule does not determine emission limits based on “generation shifting,” or the closure of fossil fuel-powered plants in favor of cleaner sources of electricity. Still, the fact that this draft rule follows the passage of the Inflation Reduction Act of 2022 (“IRA”) has enabled the EPA to be relatively stringent.

In 1963, a typical car—which ran on leaded gasoline without pollution control devices— emitted 520 pounds of hydrocarbons, 1,700 pounds of carbon monoxide, and 90 pounds of nitrogen oxide every 10,000 miles traveled. Soon thereafter, it began extolling the virtues of battery electric vehicles , which it continues to do today.

States and local air quality regulators have the legal authority to set particulate matter (PM), ozone, and nitrogen oxides (NOx) emissions standards and adopt regulations for these pollutants when they are already in attainment of the national ambient air quality standards ( NAAQS ) set by the U.S.

Critically, and as we’ll discuss in greater depth shortly, hydrogen combustion (as opposed to its use in fuel cells) also leads to greater emissions of nitrogen oxides (NOx), a toxic group of pollutants regulated under the Clean Air Act.

Cleaner cars, cleaner air Our Cleaner Cars, Cleaner Air Report showed that while pre-2004 cars make up fewer than 20% of the cars on the road, they are responsible for the majority of tailpipe pollution because they produce higher amounts of lung-damaging particulate pollution and contribute significantly more smog-forming nitrogen oxide emissions.

The rules are part of the SCAQMD’s strategy to reduce the emission of harmful nitrogen oxides (NOx) and fine particles, which contribute to smog.  This vote was closely watched because South Coast AQMD oversees air quality for areas of LA, Orange, Riverside and San Bernardino counties that are home to more than 17 million people.
