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

Green Car Congress

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. nitrogen dioxide (NO?)

New iron catalyst helps preferentially reduce NO to hydroxylamine; pollution control and clean energy

Green Car Congress

Researchers from Korea and France have shown that iron–nitrogen-doped carbon is an efficient and durable electrocatalyst for selective nitric oxide reduction into hydroxylamine. Among the major pollutants, nitrogen oxide (NO x ) accumulation can cause severe respiratory diseases and imbalance in the Earth’s nitrogen cycle.

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

The study, set in Singapore, suggests that better air quality will bring about climate co-benefits in reducing electricity generation via lower household demand, and thus mitigating carbon emissions. The same household’s energy consumption was examined over time and compared with concurrent PM 2.5 —Prof Salvo.
