At the helm is a group of human rights lawyers who say popular feeling is behind them when it comes to pollution that is literally off the charts, phys.org wrote.
"Chinese people aren't too concerned about societal problems and things that aren't happening to them personally, but this issue is different: Everyone is a victim and is personally influenced by breathing polluted air," lawyer Yu Wensheng told AFP.
He is among a group of six lawyers who began filing their suits in December after a choking cloud of haze descended on China's northeast, affecting some 460 million people.
The campaign comes amid growing public anger over China's bad air, which has fuelled protests and spurred emigration among the wealthy.
Yu said the importance and impact of the pollution suit 'far exceeds' his previous human rights cases.
Even acquaintances opposed to Yu's politics and police at a client's detention center had expressed support, he said, noting it was 'very unusual'.
In December, a week of thick haze forced cities across the northeast to go on 'red alert' for nearly a week, closing schools, factories and construction sites and taking around half of vehicles off the roads.
As visibility dropped and airports cancelled hundreds of flights, people took to social media to vent their rage against a government that had long promised to solve the problem.
But comments about the heavy smog quickly began disappearing from the web.
On Wednesday, the Meteorological Administration also ordered local weather bureaus to stop issuing smog alerts, which authorities said was intended to improve coordination.
A document submitted by Yu's associate to the Beijing Second Intermediate People's Court accused the government of 'severe dereliction of duty' in pollution management and sacrificing human health in pursuit of 'toxic GDP growth' by turning a blind eye to the excessive emissions of local companies.
The lawyers have little hope of winning or even successfully filing their cases and are viewing the suits as 'mostly symbolic', Yu said.
Toxic smog in China has caused schools, factories, construction sites, roads and airports to close.
The document asked for authorities to publish an apology online and in the local state-run newspaper for a week, and hand over compensation of 65 yuan ($9.50) for the price of his smog mask and 9,999 yuan for emotional damages.
He hopes the suits will help keep the issue in the public eye, adding he wants to inspire others to file complaints.
"Our main goal is to raise people's awareness of pollution and wake them up to how the government should bear responsibility for its inaction and ineffectual response," he said.
Notably, China can clear the skies for important occasions such as the 2014 APEC summit or the 2008 Olympics, but does so selectively due to the high economic cost.
"They can do it, but they do not," Yu said.
Another lawyer Ma Wei, who is suing the city of Tianjin, said he has received no official response even weeks after the court was legally required to issue one.
Instead, the public security bureau and other authorities have tried to pressure him to retract his suit.
"I refused and told them, 'I'm doing this so that you can breathe clean air, too'," he said.
