RHI Magnesita strives to be the sustainability leader in its sector. The company’s sustainability strategy is based on the 10 Principles of the UN Global Compact covering human rights, labour, environment, and anti-corruption.

Focus areas include:

RHI Magnesita has a dedicated Corporate Sustainability Committee that monitors performance related to climate change, environment, health and safety, stakeholder relations, and other ESG risks. Executive and functional leaders are accountable for delivering sustainability priorities, and the Global Sustainability Team is responsible for external reporting, assessing sustainability-related risks, and liaising with the Board and key internal and external stakeholders. They also provide regular updates to the Corporate Sustainability Committee. A collaborative approach ensures co-ordination with key functional areas such as Health & Safety, environment, sustainable technology and decarbonisation, recycling, finance, risk management and compliance, and procurement. This governance framework
facilitates a comprehensive and integrated
approach to sustainability.


RHI Magnesita conducts a materiality assessment as part of our sustainability reporting process. This helps us to identify issues that are important to the company’s long-term value creation and the demands of our stakeholders.

Our material topics are: Health and Safety, Recycling, Climate Change and Decarbonisation, Other Emissions, Energy Efficiency, and Diversity are material topics. See our actions regarding these topics within our 2025 Targets below.

2023 Materiality Matrix RHI Magnesita

This analysis included the double materiality concept, which used three different impact levels (low, medium, high) to assess topics related to the value of the company. These are based on the Group’s risk management approach and comprise four dimensions (compliance, strategy, financial, and operation), as well as the likelihood of the risk becoming true.

Targets and Performance

RHI Magnesita’s 2025 sustainability targets were defined in 2019 based on engagement with internal and external stakeholders. The following areas of materiality were identified: CO2 emissions, Energy use, Recycling, Diversity, Health & Safety, NOx and SOx emissions. The results of this analysis will be the base for the existing targets, and for setting up new targets.

RHI Magnesita actively supports the UN Sustainable Development Goals (SDGs).
