Substantial increases in sulphur dioxide (SO2) and nitrogen oxides (NOx) emissions are likely to occur in the key emerging economies in the coming decades. Compared to the year 2000, emission levels of SO2 are projected to be 90% higher and NOx 50% higher in 2050.
What is the most accurate air quality website?
Airnow.gov is the gold standard when it comes to knowing the precise measurement of pm 2.5.
Can air quality be predicted?

for the pollutant. AQI values at and below 100 are generally considered to be satisfactory. When AQI values are above 100, air quality is considered to be unhealthy, at first for members of populations at greatest risk of a health effect, then for the entire population as AQI values get higher (greater than 150).
