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. When action is taken on these classical pollutants—particulate matter (PM), ozone (O?), and carbon monoxide (CO)—it also has an impact on other damaging pollutants.

The human health benefits associated with improvements in air quality related to the reduction in greenhouse gas emissions improvements can offset 26–1,050% of the cost of US carbon policies, depending upon the type of policy, according to a new study by a team from MIT. Carbon-reduction policies significantly improve air quality.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Eventually, they’ll add equipment to spray tiny aerosol particles of calcium carbonate, the compound found in limestone, blackboard chalk, and Tums antacids.

While they do not deplete the ozone layer, many are highly potent greenhouse gases whose use is growing rapidly as replacements for ozone-depleting substances being phased out under the Montreal Protocol. Left unabated, HFC emissions could grow to nearly 20% of carbon dioxide emissions by 2050, a serious climate mitigation concern.

HFC-23 is a very potent greenhouse gas, with one tonne of its emissions being equivalent to the release of more than 12,000 tonnes of carbon dioxide. The researchers hope to work with other international groups to better quantify India and China’s individual emissions using regional, rather than global, data and models, said Dr Rigby.
