Thrifty fireworks lessen China's smog pain

China sees less smog during the lunar new year celebrations, as people have shown "quiet" support for the government call for fewer fireworks.

Most of the megacities reported less air pollution, good visibility and less noise on the eve of China's Spring Festival. The Spring Festival falls on Friday this year.

Beijing's air quality on the eve of the Spring Festivalwas "much better" than last year with the average PM 2.5 reading between 140-160 micrograms per cubic meter from 6 p.m. on Thursday to midnight.

The municipal environmental monitoring center said that last year, Beijing recorded its highest ever reading (over 1,000) after a firework frenzy on the lunar new year's eve.

The capital also had fewer fires and injuries on Thursday night.

The municipal government was so thrilled that it expressed gratitude in a public letter on Friday to local citizens who answered its call of replacing fireworks with flowers and electronic substitutes for celebrations.

The letter also calls for continuing such "environment-friendly " practices in coming days.

Harbin, the capital of northeast Heilongjiang Province, also experienced a rare clean lunar new year's eve as the average PM 2.5 reading stood at 103 micrograms per cubic meter after the pyrotechnic peak at midnight.

Chinese people light firecrackers and fireworks to celebrate the Spring Festival, the beginning of the lunar new year. Traditionally, the noise was believed to scare away evil spirits and bad luck. However, with regular smog suffocating China in recent years, the contribution of fireworks to air pollution has drawn the attention of authorities.

Posts and cheesy one-liners calling for people not to set off firecrackers are circulating on Chinese social media platforms.

"The efforts has paid off, but we definitely need to do more," Tang Lili, an official with the environmental monitoring center of east China's Jiangsu Province told Xinhua, referring to an air quality report.

The report showed the peak PM 2.5 reading on Thursday night and Friday morning was 568 micrograms per cubic meter, a remarkable drop compared with last year's 800, but still far above "clean".

"Factories have been closed for the holiday and there are far fewer cars on road, so the fireworks are the main pollutant," said Tang.

"We still have a long way to go to raise public awareness and the government should take tough measures when necessary," she said.

In this regard, Beijing takes the lead. The capital cut the number of licensed firecrackers and fireworks retailers by 12 percent this year to 1,178 stalls. For the first time, municipal authorities required retailers to record the identities and phone numbers of buyers of more than five boxes of fireworks. If the customer refuses to give the information, retailers are obliged to refuse sale or sell a smaller amount.

Statistics on fireworks and firecrackers from the Beijing municipal office showed as of Thursday, more than 126,000 boxes of fireworks had been sold, down 52 percent from last year.

In December, the office announced an emergency ban on fireworks if orange or red air pollution alerts were issued.

An orange alert means forecast pollution of over 300 micrograms per cubic meter for the following 24 hours, or of over 200 micrograms per cubic meter for 72 hours.

Residents receive cell phone text messages notifying them of alerts, and the police will prevent the public from flouting the ban, said Yu Lianwei, an official with Beijing's public security bureau.
