California has a longstanding leadership role on transportation pollution, and the Clean Air Act grants the state the right to set strong vehicle emissions standards. We know the truck industry has a number of technological solutions to reduce its emissions, but we need regulators to take action to make it happen.

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.

But with the recent influx of government incentives for hydrogen production, new and improving production and storage technologies, and greater political will than ever before, H 2 ’s reputation is gaining favor. But for many of these use-cases, hydrogen doesn’t do the job particularly well, at least as compared to existing technology.

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. and Sierra Club v.

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.

By: Lesley Foxhall Pietras On August 8, 2011, the Environmental Protection Agency (EPA) published a far-reaching Clean Air Act rule intended to address the interstate transport of sulfur dioxide (SO2) and nitrogen oxides (NOx) from upwind to downwind states. See 76 Fed. 48208 (Aug.

This decision wrongfully precludes the agency’s authority to set robust power plant carbon pollution standards in line with today’s technologies and practices adopted on a sector-wide basis. Congress, too, must act quickly to pass the months-long stalled budget reconciliation bill—with critical climate and energy components.
