Smog is a hot topic at the Two Sessions with Premier Li Keqiang vowing to enforce environmental regulations in the Government Work Report.

The efforts made by governments at all levels to curb pollution have had an positive effect in the past year, which to many marks the first year that the air pollution has been reined in. More importantly, a mechanism for cross-regional cooperation involving both short-term emergency measures and long-term institutional endeavors, is taking shape.

According to statistics released by the Ministry of Environmental Protection, all 74 major Chinese cities subject to air quality monitoring of PM2.5, carbon monoxide and ozone, reportedly met the national standards for clear air on 241 days on average last year. For the Beijing-Tianjin-Hebei area, which has been plagued by frequent and severe smog in recent years, the figure was 156 days. The concentration of PM2.5 in the Beijing-Tianjin-Hebei area was reduced from 106 micrograms in 2013 to 93 micrograms over the same period. Such monitoring data indicate that the country's tough pollution fight throughout 2014 began to be effective. However, despite the decrease in PM 2.5 concentration, the figure of 93 micrograms was still nearly three times higher than the standard level.
