US EPA proposes to retain existing NAAQS for ozone

Green Car Congress

JULY 14, 2020

The US Environmental Protection Agency (EPA) is proposing to retain, without changes, the existing, more stringent 2015 National Ambient Air Quality Standards (NAAQS) for ozone. From 2017 to 2019, ozone concentrations fell 4%. During that same time, national average ozone concentrations have dropped 25%. Background.

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

The largest systematic study ever conducted of human volunteers exposed to ozone air pollution has found no evidence of effects on the heart in its healthy, older participants, but did find effects on the volunteers’ ability to breathe, even at low ambient levels. Possible pathways by which ozone may cause adverse health effects.

Emissions of potent GHG HFC-23 have grown, contradicting reports of huge reductions

Green Car Congress

JANUARY 23, 2020

Despite reports that global emissions of the potent greenhouse gas, HFC-23, were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values. As a result, they reported that they had almost completely eliminated HFC-23 emissions by 2017.

The data showed a 50% jump in efficiency each time the panels were cleaned after being left alone for several weeks. The manmade particles are also small and sticky, making them much more difficult to clean off. If cleanings take place every two months, those numbers jump to 25 or 35%. —Michael Bergin. 7b00197.

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. Transportation.
