Improving air quality in order to protect the environment and public health from air pollutants while complying with statutory standards for permissible emissions.
Norilsk Nickel is committed to the UN Sustainable Development Goals 3 “Good Health and Well-Being” and 11 “Ensuring openness, security, resilience and environmental sustainability of cities and towns”. The Company considers it crucial to reduce negative environmental impact of cities, including by focusing efforts on air quality improvement.
Reduction of SO2 emissions by 2035
Reduction of SO2 emissions by 2035
As a result of Nornickel’s production activities, more than 60 pollutants enter the air, 96% of the total emissions are sulfur dioxide.
To achieve our quantitative targets at Norilsk and Kola sites, we are running the

Ongoing capacity upgrades
At the end of 2024, Nornickel launched an automatic air quality monitoring system in Norilsk. This is the first project launched in the Arctic Circle and one of Russia’s first projects enabling real-time assessment of air pollution levels.
For the project, 16 environmental monitoring stations were installed in the Norilsk Industrial District to measure the air content of sulphur dioxide (SO2), hydrogen sulphide (H2S), carbon monoxide (CO), nitrogen dioxide (NO2) and dust, as well as temperature, pressure, and humidity.
Today, the monitoring data are used to calculate an air quality index, which is posted on the
In July 2025, the automatic air quality monitoring system in Monchegorsk was officially launched. The new system represents an advanced digital platform that provides round-the-clock monitoring of air quality in real time. It combines data from 13 environmental monitoring stations located in the city. The collected data is processed and published in real time on the official website of the Monchegorsk administration in the form of an air quality index, which is calculated based on the maximum permissible concentrations of pollutants.

In 2025, the Group’s total emissions amounted to 1.2 mt, down 8% y-o-y.
The decrease in emissions is due to the continuation of the implementation of the Sulfur Programme at the Nadezhda Metallurgical Plant.
