Magnitogorsk Iron and Steel Works has risen from tenth to fourth place in World Wildlife Fund Russia's 2021 transparency ranking of environmental information for mining and metallurgical companies in Russia.

In 2021, 38 companies from the metals and mining sector were included in the WWF Russia rankings. WWF Russia has been issuing annual rankings of environmental responsibility of Russian companies since 2017; their purpose is to help improve the environmental situation in Russia, as well as to raise public and business awareness of the importance of timely and full disclosure of information about the environmental impact of production.

Companies participating in the rating are evaluated according to three criteria: the quality of environmental management, the level of environmental impact and the completeness of information disclosure. MMK ranked particularly high on the third criterion, taking joint third place.

In 2021, MMK significantly strengthened its position in international ratings that assess the quality of environmental reporting disclosure. For example, in September 2021, AK&M rating agency rated MMK's environmental disclosure as one of the best in Russia. And in November 2021, MMK was ranked first in the ESG transparency rating of Russian companies and banks compiled by Expert RA rating agency. MMK received the highest score, including in the environmental information disclosure criterion.
