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.

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.,

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

Green Car Congress

NO x emissions have not been decreasing as expected in recent years (2011–2015) when comparing top-down estimates from satellites and surface NO 2 measurements to the trends predicted from the US Environmental Protection Agency’s emission inventory data, according to a new study by an international team of researchers.

California ARB moves forward with climate and air quality actions

Green Car Congress

CARB approved the State Strategy for the State Implementation Plan ( State SIP Strategy ), which describes CARB’s commitment for further reducing vehicle emissions needed to meet federal air quality standards over the next 15 years. emissions by more than 20%. emissions by more than 20%.

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

Baua Electric

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. For vehicle emission rates, those numbers dropped 2.6% 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

The California Air Resources Board released the draft proposed first update to the AB 32 Scoping Plan, which guides development and implementation of California’s greenhouse gas emission reduction programs. California’s zero emission vehicle (ZEV) regulation is also driving a transformation of the fleet. Transportation.

The New Supersonic Boom

Cars That Think

Meanwhile, environmentalists were voicing concern—about how noisy such aircraft are taking off, about the possibility that their high-altitude emissions would erode the ozone layer, and about how disruptive the sonic booms would be. The last of these issues was perhaps the most vexing, prompting the U.S. Boom Supersonic.
