Policy & Regulation:
-) Emilia-Romagna in northern Italy
The emissions from light diesel-powered vehicles are a major cause of production of fine dust. The aim of the “ecobonus” is to replace light commercial vehicles powered by diesel that transport and deliver goods of up to 3.5 tonnes
Ecobonus
-) The incentives will cover the replacement of polluting Euro 3 diesel commercial vehicles, with more environmentally friendly Euro 6 bi-fuel vehicles, including petrol-LPG, petrol-CNG, petrol-electric and electric. Companies will receive a bonus of up to 2,500 Euros to renew their fleet, with a single contribution being granted for each applicant.
“It is one of more than 90 actions that the Plan for quality air expects to put in place to halve the concentration of PM10 and cut from 64% to 1% the population exposed to more than 35 peaks per year.”
-) Brussels, Belgium
Depending on the concentration of fine dust from November to March, emergency plans are in operation. The speed of traffic in urban areas is 50km per hour (usually limited to 70 to 90 km/h)
Free public transportation in the city, free bicycle rental fees, no firewood fuel heating, and limited heating temperature below 20 degrees Celsius.
-) China's Jingjinji (Beijing, Tianjin, Hebei).
Implementation of countermeasures for comprehensive air pollution management in the fall and winter from October to March.
Elimination and relocation of spawning o (small businesses that cause unauthorized environmental pollution), strict punishment for discharging trucks exceeding the standard, etc.
-) Stuttgart, Germany
From October 15th to April 15th, roughly 20-35% discount on transportation in high-concentration cities and 50% discount on parking for electric vehicles.

-) Wind Effect
PM10 concentration decreases with the wind velocity increased, and the concentration reaches to the minimum value when the wind velocity reaches to 1.0-2.0 m/s.
-) Stuttgart, Germany
The health of citizens was often threatened by air pollution emitted from factories. For this reason, Stuttgart naturally reflected the wind road in the city and construction plan while rebuilding the destroyed city after the war. In particular, it has created a wind path that naturally induces the flow of cold air generated in mountainous areas outside the city and blows into the city center in the opposite direction of the city. This is because the cold air blowing from the clean area not only cools the city center, a high-density development area, but also makes the air deteriorated by the atmospheric environment clean. At the result, they had a 30% reduction effect to reduce particulate Matter.
[Planting trees]
Overseas, the fine dust season system was introduced targeting high concentrations of fine dust.
Overseas city that introduced the fine dust season system
Planting trees can help in reducing PM in the atmosphere.
A study conducted in the city of Baoji, China proved that the difference of PM level in the atmosphere when their was a difference in the vegetation.Changing the horizontal and vertical structure of vegetation and vegetation type can contribute to the reduction of PM2.5 and PM10 concentrations to a certain extent.
