The Comprehensive Air Quality Index indicator for Magnitogorsk has almost halved over the past two years, official data shows, indicating a twofold improvement in air quality. The reading is the lowest in the history of Magnitogorsk. MMK has spent more than RUB 21 bln on environmental measures since 2017. The CAQI for the city of Magnitogorsk for the first nine months of 2019 stood at 7.62, compared to 13.4 for the same period in 2017. The data is obtained from air quality observation stations belonging to the Russian Federal Service for Hydrometeorology and Environmental Monitoring (Roshydromet) and MMK. Readings are conducted using Roshydromet methodology).

A number of MMK’s environmental projects have contributed to the sharp increase in air quality:

1. Launch of the new sinter plant No. 5 in July of 2019 (RUB 30 billion). The plant is equipped with the latest environmental technologies, helping cut dust emissions in half (by 2.1 thousand tonnes per year), sulphur dioxide emissions by four times (by 3.5 thousand tonnes per year) and benzo(a)pyrene emissions by 16 times.

2. Construction of aspirations systems at blast furnaces No.9, No. 10 and No.1 took place in 2017-2018, reducing dust emissions by a total of 1.14 ths tonnes per year.

In 2017, reconstruction of the sinter plant's sulphur recovery facilities improved the efficiency of air purification by up to 95%. Total investment in the project amounted to RUB 3.5 billion.

3. Implementation of the programme to reduce dust and gas emissions during coke production reduced the concentration of benzo(a)pyrene by 22% during the first nine months of the year.
