NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

The study examined utility meter readings of 130,000 households—a 1-in-10 random sample of all households in Singapore—from 2012 to 2015. The reasons were two-fold: (i) increased air pollution led to households staying indoors more to mitigate the pollution impact; and (ii) PM 2.5 —Prof Salvo.

Study: traffic density, wind and air stratification influence concentrations of NO2

Green Car Congress

In connection with the effects of the COVID-19 pandemic, satellite measurements made headlines showing how much the air pollutant nitrogen dioxide (NO 2 ) had decreased in China and northern Italy. In 2018/2019, for example, various measures were taken in Germany, ranging from a reduction in the number of lanes (e.g. in Stuttgart).

OECD: governments should make better use of energy taxation to address climate change; “meaningful” increases limited to road sector

Green Car Congress

Greater reliance on energy taxation is needed to strengthen efforts to tackle the principal source of both greenhouse gas emissions and air pollution, according to a new OECD report. In 2015, outside of road transport, 81% of emissions were untaxed, according to the report. In road transport, 97% of emissions are taxed.
