The latest data on air quality in Vienna show that the air quality in Vienna in 2016 was the best in the last 50 years, ie, since the beginning of the 70s of the last century. The values of suspended dust particles last year so were 13 percent lower than in 2015, the year of the beginning of measurements in 2002 was considered the year with the lowest concentration of dust.
A positive development is the result of a number of measures the city government to improve air quality, and the City of Vienna is currently implementing the third package of measures covering all groups of pollutants. These measures also include encouraging public transport, thermal rehabilitation of buildings, encouraging the use of central heating and effective winter service that uses modern technology of wet salt.
In Vienna, the upper measured values of dust halved compared to 2003 and significantly lower than the limit value of 40 mg / m3. The EU directive, which means that the daily concentration of 50 micrograms of dust exceed a maximum of 35 days a year in Vienna was realized in the past five years. Higher values in 2015 were both measured only for 14 days.
The main polluters in this include transport, construction and heating private households, but according to the Technical University of Vienna as much as 60 percent of the dust in Vienna comes from elsewhere.
Neither sulfur dioxide which in the 1980s considered the main cause of acid rain in Vienna today is no longer a problem, and the values of the measurements are reduced by 96 percent. Measures of the city administration which contributed to this prohibition are using fuel with sulfur and ban the installation of new furnaces on coal and fuel oil.
