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.

Texas study finds PHEV use could increase ozone at night, decrease ozone during the day

Green Car Congress

A study by researchers at the University of Texas found that in general, use of plug-in hybrid electric vehicles (PHEVs) can lead to an increase in ozone during nighttime hours (due to decreased scavenging from both vehicles and EGU stacks) and a decrease in ozone during daytime hours.

Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

California’s latest greenhouse gas data shows that while the state continues to stay below its 2020 target for emissions, there is much more work to do to achieve carbon neutrality by 2045. Total statewide 2018 GHG emissions were 425.3 million metric tons between 2017 and 2018, the first such decline since 2013.

Study finds global emissions of ethane and propane underestimated by more than 50%

Green Car Congress

When ethane and propane—the most abundant non-methane hydrocarbons (NMHC) in the atmosphere—mix with nitrogen oxides from vehicles and power plants they form tropospheric ozone—a key component of smog and directly linked to increases in mortality. —Professor Ally Lewis, a co-author of the study. Read, Lucy J.
