Study finds significant slowdown in decrease of NOx emissions in US; implications for air quality management

Green Car Congress

They found that levels of pollutants that can contribute to the formation of ground-level ozone, or smog, have failed to continue a fairly steady decline as estimated by the US Environmental Protection Agency. These results show that meeting future air quality standards for ozone pollution will be more challenging than previously thought.

California ARB moves forward with climate and air quality actions

Green Car Congress

For heavy-duty vehicles, the State SIP Strategy calls for combustion engine technology that is effectively 90% cleaner than today’s standards. Approximately 70% of the reductions needed to meet the ozone standard in the South Coast in 2031 would come from existing or proposed regulatory actions. emissions by more than 20%.

Tohoku team finds swirling ammonia in combustion chambers can help reduce NO emissions

Green Car Congress

So far, ammonia has been considered as a fuel when blended with gasoline, diesel, hydrogen and methane fuels to reduce the proportion of carbon-based fuels and their emissions that contribute to climate change. While it contains a great deal of hydrogen, it is less expensive and less flammable than pure hydrogen, making it safer to transport.

California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

These reductions have come from strong efforts to reduce on-road vehicle emissions, especially diesel particulate matter. Also, Senate Bill 605 (Lara, 2014) requires ARB to develop a plan to reduce emissions of SLCPs, while SB 1383 requires the Board to complete and approve the plan by 1 January 2018.
