WHO issues new, lower Global Air Quality Guidelines for classical pollutants

Green Car Congress

SEPTEMBER 25, 2021

New WHO has issued new Global Air Quality Guidelines (AQGs) that reduce levels of key air pollutants, some of which also contribute to climate change. Since WHO’s last 2005 global update, there has been a marked increase of evidence that shows how air pollution affects different aspects of health. Source: WHO.

Probability distribution for the committed warming by GHGs between 1750 and 2005. Cutting HFCs, black carbon, tropospheric ozone, and methane can buy us about 40 years before we approach the dangerous threshold of 2°C warming. HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals.

AUGUST 15, 2019

Long-term exposure to ambient air pollutants, especially O 3 (ozone), is significantly associated with increasing emphysema, according to a new study led by the University of Washington, Columbia University and the University at Buffalo. The annual averages of ozone levels in study areas were between about 10 and 25 ppb.

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

Green Car Congress

JANUARY 23, 2020

That the reduction has not materialized—and that global emissions have instead risen—is a puzzle, and may have implications for the Montreal Protocol, the international treaty that was designed to protect the stratospheric ozone layer. This is not the first time that HFC-23 reduction measures attracted controversy.

Following this BAU scenario, the researchers projected that air quality for the global average citizen in 2050 would be almost comparable to that for the average citizen in East Asia in the year 2005—an outcome which underscores the need to pursue emission reductions, according to the authors.

Study identifies Bakken Formation alone as responsible for ~2% of global ethane emissions

Ethane reacts with sunlight and other molecules in the atmosphere to form ozone, which at the surface can cause respiratory problems, eye irritation and other ailments and damage crops. Between 2005 and 2014, the Bakken’s oil production jumped by a factor of 3,500, and its gas production by 180.
