Pollution prevention

Focused on the active prevention of any identified pollution risk from the Company's activities, in accordance with the key pillars of its Environmental Policy, MYTILINEOS embraces and fully integrates the internationally accepted Principles of Responsible Business of the UN Global Compact, within which the protection of the environment is highlighted as a special area of commitment. In particular, through:

• Principle 7, the Company supports a precautionary approach to environmental challenges.
• Principle 8, undertakes initiatives to promote greater environmental responsibility.
• Principle 9, encourages the development and diffusion of environmentally friendly technologies.

Through its business practices and overall approach to environmental issues, MYTILINEOS is committed to promoting a work and social environment that demonstrates respect for Human Rights, and its ongoing concern to preventing environmental incidents that could call into question the protection of Human Rights directly related to the natural environment, in line with the key pillars of MYTILINEOS Corporate Social Responsibility Policy and the Human Rights Policy which sets out the basic principles relating to the respect for human rights and sets the framework for managing employment.

Impacts

Failure to prevent and manage the relevant risks could have a significant impact on the Company’s economic, industrial and natural capital, leading to reduced value generated either through increased costs for addressing these incidents, or through possible administrative sanctions that may be imposed or the Company’s possible inability to continue to conduct its activities.

The proactive management of pollution risks is directly linked to the safe and socially and environmentally responsible operation of all the Company's facilities, as well as to actual positive impacts such as: the prevention of any land and marine pollution and the proper management (recycling, reuse) of waste and spills of hazardous materials into the soil, in accordance with the internationally agreed frameworks, reducing risks to human health and the environment.
