CSIRO study finds ozone uptake in oceans much lower than previously thought

Green Car Congress

CSIRO scientists have developed a new way to account for ozone in computer simulations of the climate. This latest modeling shows that the oceans take much less ozone out of the atmosphere than previously thought. Ozone (O 3 ) is formed by reactions of chemicals such as nitrogen oxides and volatile organic compounds—i.e.,

TOAR shows present-day global ozone distribution and trends relevant to health; public database

Green Car Congress

Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb. Trends in daily maximum ozone levels (known as 4MDA8) at urban and non-urban sites.

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

Actions to promote ZEVs in these applications are important to foster further technology development so they become suitable for broader use in the future. 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%.

German-Chilean consortium investigating new ways of reducing arsenic in copper concentrates: ReAK

Green Car Congress

As a result, the amount of arsenic to be deposited will increase in the future, particularly given that there are currently no industrial uses for arsenic. Fraunhofer IWKS launched a first project in 2018, which brought together a consortium of numerous German and Chilean partners from both research and industry.

UC Berkeley study confirms that yes, EVs do what they promise to do

Perhaps even more importantly, the study offers some quantifiable, granular data about how much electric vehicles are impacting emission rates in the here and now, not in the foreseeable future. Not that these numbers will blow you away, mind you, but still, it’s good news.

Calif. ARB releases GHG scoping plan update; more ZEVs, “LEV IV”, MD and HD regulations; ZEV for trucks; more LCFS

Green Car Congress

Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. However, to achieve the needed transportation GHG reductions and the corresponding 2032 ozone standards, the market uptake of advanced technologies will need to be accelerated. Vehicle technology.
