New Data Shows Beijing’s Air Pollution Progress Reverses in March

After several months of progress cutting PM2.5, Beijing saw a sharp reversal this March, according to the latest data.


In years past, Beijing’s particulate pollution normally peaks in January and decreases each month closer to summer.



However, this year has seen the exact opposite trend, with PM2.5 increasing 265% from January to March.



Maybe March’s rise was due to the sandstorm that hit Beijing? The data shows that this trend was in place even before the sandstorm. Beijing averaged 96 micrograms in the first half of March—before the sandstorm. Data from another northern city, Xi’an, also saw a worse March than February.



Is this trend due to unfavorable weather patterns? Could it be that authorities are relaxing enforcement of pollution regulations after a strict winter of enforcementFor now, air-breathers in Beijing can only hope this upward trend is short-lived.
